The other co-winner at Teplitz Schoenau 1922 was Rudolf Spielmann. Like Reti, he was a top 20 player for a long time (Sonas has him there from September 1908 to September 1935), but like Reti he didn't quite get to the very top, peaking at #6. Also, like Reti, he was the author of a classic book ( The Art of Sacrifice in Chess). However, the comparisons usually end there. In contrast to the hypermodern Reti, Spielmann was a classic attacking player. Further, Spielmann is not a name generally associated with the endgame. We previously saw his misadventures in a simple rook ending against Alekhine at New York 1927. However, Nimzovich pointed out "...during the New York tournament of 1927, he came to the realization the he was not playing rook endings accurately enough; a year later, at Bad Kissingen 1928, he had already become a first-class specialist in such ending!" Fine uses several of Spielmann's games in the BCE section on R+2P vs. R+P with disconnected passed pawns both before and after 1927, so we can partially judge Nimzovich's assessment.

San Sebastian 1912 was one of the strongest tournaments that year. Spielmann
and Nimzovich tied for second a half point behind Rubinstein. Spielman could
have tied for first if he had squeezed out the win in rook ending in the final
round against Paul Leonhardt. After **35...Kxd6**

Black has an extra pawn, but there are still technical difficulties to overcome.
**36.g5 fxg5 37.hxg5 Kc6 38.Kc2 a5 **
In the tournament book,
Meises gives this move an exclam,
noting that Black has nothing after
38...Ra2+ 39.Kb3 Rg2 40.Re1 Rxg5 41.Re6+ Kb7 42.Kb4
With the text, Black takes away the b4 square so ...Ra2+ is now a threat.
and after
**39.Kb2 b4**
Black has opened a route for his king into White's position.
However, it appears that White can still hold the draw.
**40.cxb4! axb4 41.Rc1+ Rc3 42.Ra1 **
42.Rxc3+? bxc3+ 43.Kxc3 Kb5! 44.Kb3 g6! and Black has the opposition.
**42...Rg3**

**43.Ra6+? **
It looks natural to go after Black's g-pawn while defending the pawn on g5.
However, White should instead go after the Black d-pawn,
leaving Black with more widely split pawns.
In the game with b and d-pawns the Black king can guard both of them
while moving forward. It looks like White just makes it to a draw after.
43.Rc1+! Kb5
* (43...Kd6 44.Rd1! Rxg5 45.Kb3! *
doesn't promise Black anything.*) *
44.Rc5+! Ka4 45.Rxd5! Rg2+ 46.Kc1! Kb3 47.Rc5! Rg1+ 48.Kd2 Kb2 49.Rc7 Rxg5
50.Rd7 b3 51.d5! Kb1 52.Rb7 b2 53.d6! Rd5+ 54.Kc3! Kc1 55.Rxb2!
**43...Kb5! 44.Rg6 Kc4 45.Rxg7 Rg2+! 46.Kc1**

**46...Kxd4? **
This is the starting position for BCE-360.
Mieses points out the missed win here with 46...Kc3
but his variation has some errors in it
47.Rc7+ Kxd4 48.Rg7 is back to BCE-360, but with Black to move.
Fine also looked at this position and showed the correct method from here
48...Kc3 49.Rc7+ Kd3
* (49...Kb3 50.Rg7 d4 51.g6 d3 52.Rg8 d2+ 53.Kd1 Kb2 54.g7 b3 55.Rd8 Rxg7 56.Rxd2+ Kb1 *.
It is strange that he didn't use this same method in the analysis of
47. Rg8 in the White to move position, instead repeating Mieses error
with ...d4.*) *
50.Rg7 d4?
* (*Black should return with *50...Kc3) *
51.g6! Rc2+ 52.Kb1! Rc6 and now 53.Kb2! holds the draw rather than Mieses variations
* (53.Rb7? Rxg6! or 53.Rg8? Kc3 54.g7 Rc7!!) *
**47.g6! Kd3 48.Rd7! d4 49.g7 Rg6 50.Kb2 Rg1 51.Kb3 1/2-1/2**

Of course, Reti's contributions to chess were not limited to endgame studies. Reti was also the author of two classic books (Modern Ideas in Chess and Masters of the Chessboard) As a player, Sonas has him entering the top 20 in 1914 and remaining there until his untimely death in 1929. He was one of the leading practioners of the hypermodern school. The Reti Opening is righly named after him after he used it to end Capablanca's 8-year undefeated streak in 1924 (he also defeated Alekhine in the same tournament).

BCE-413c is based on Reti's game as Black against Karl Treybal in the Teplitz Schoenau tournament in 1922. This was a relatively strong tournament, but many of the very top players of the day (Capablanca, Alekhine, Vidmar, Lasker, and Bogoljubow) were absent. The tournament was a success for Reti who tied for first with Spielmann despite losing to two of the tail enders (Mieses and Johner). Reti absolutely dominated against the top finishers scoring 5.5/6 against the top half of the crosstable.

Against Treybal the players reached a rook ending after **29...Kxf8**

**30.h4 **
The tournament book suggests
30.Kg1 Rxc2 31.Rxb7 with the following variations
**a) ** 31...Rxa2 32.Rd7 Ra4 33.h4 Ke8 34.Rd5 d3 35.Rxd3 Rxh4 36.Ra3
**b) **31...Ke8 32.Kf1 Rxa2 33.Rb4 d3 34.Rd4 d2 35.g3 a5 36.Ke2 d1Q+
* (36...a4 37.Rxd2 Rxd2+ 38.Kxd2 h4) *
37.Kxd1 Rxh2 38.Ra4 Rh3 39.Rxa5
**c) **31...d3 32.Rd7 d2 33.Kf1 Rxa2 34.g3 a5 35.Ke2
**30...Rxc2 **Here, Treybal grabbed the wrong pawn.
**31.Rxb7? **
31.Rxd4 Rxa2 32.Rd5 b5 33.Rxh5
is the starting position for BCE-413c
Besides 33...b4 as in BCE the tournament book also gives the alternative
drawing line
33...Kg7 34.Rc5 b4 35.Rc7+ Kf6 36.Rb7 a5 37.Kh2 Kf5
* (37...Ra3 38.g4 Ke5 39.g5 Kf5 40.Rb5+ Kg4 41.g6 Rh3+ 42.Kg2 Rg3+ 43.Kf2 Kxh4! 44.Rxa5) *
38.Kh3 Ra3+ 39.g3! b3 40.Rb5+ Ke4 41.h5 a4 42.h6 Ra1! 43.Kg2 Ra2+ 44.Kh3
**31...d3 32.Rd7 d2 **
The threat of ...Rc1+ means White also loses the a-pawn.
Reti conducts the techincal phase impeccably.
**33.Kh2 Rxa2 34.Kg3 Ke8 35.Rd4 a5 36.Kf3 a4 37.Ke2 a3 38.Ra4 Kd7 39.Ra6 Kc7 40.g3 Kb7 41.Ra4 Kc6 42.Ra8 Kb5 43.Ra7 Kb4 44.Rb7+ Kc3 45.Rc7+ Kb3 46.Rb7+ Kc2 47.Rc7+ Kb1 0-1**

Jerorme Bosch is probably best known for his
Secrets of Opening Surprises books.
His survey in Yearbook 128 shows that he can delve beyond earlier
deviations as well.
He examines a dynamic variation in the London System where
White swaps his b2 pawn for Black's c5 pawn.
This line appeared in the 4th round of the Olympiad in the match
between Slovenia and Switzerland with Jure Skoberne taking on
Nico Georgiadis.
**1.d4 Nf6 2.Nf3 d5 3.Bf4 c5 4.e3 Nc6 5.Nbd2 Qb6 6.dxc5 Qxb2 **

The starting position for the survey.
**7.Rb1 Qc3 8.Bb5 e6 9.0-0 Be7 10.Ne5 Bd7 11.Nd3 0-0 12.Bc7 b6 **
Bosch says this looks scary, but objectively gives White no advantage
**13.cxb6 axb6 14.a4 Qa5 **

The position is equal according to Bosch.
The engines agree, but with only two sets of pawns exchanged there is still
a board full of pieces, so the position still contains play.
**15.c4 Rfc8 **
15...Rac8 and 15...Qa7 have been tried previously, both unsuccessfully.
However, the move in the game doesn't really work out that well as the rook soon returns to f8.
**16.Bg3 Qa7 17.Bh4 dxc4 18.Bxf6 Bxf6 19.Nxc4 Rab8 20.Nd6 Rf8 **
see the note to Black's 15th move
**21.Qh5 Be7 22.Nc4 Na5 23.Nce5 Bxb5 24.axb5 Bd6 25.Ra1 Qb7 26.Ra4 Bxe5
27.Nxe5 f6 **
Instead of weakening the kingside
27...Qd5 angling for a queen trade might be better.
28.Rh4 h6 and it isn't clear how White continues the attack since
29.Rg4 doesn't really threaten Qxh6 because of the loose knight on e5.
However, Black can't immediately take advantage of this because
29...f5? * (*Black should prepare this move with *29...Rb7) *
30.Rxg7+ Kxg7 31.Rd1 Qxd1+ 32.Qxd1
leaves Black with the same problems he faced in the game
**28.Rh4 h6 **
28...fxe5 29.Qxh7+ Kf7 30.Rg4 Rg8 31.f4 e4 32.f5 e5 33.f6
**29.Ng4 Rf7 30.Rd1 Rc8 **
30...Kf8 31.Nxh6 gxh6 32.Qxh6+ Ke7 33.Qg6
**31.Qg6 Kf8 32.Rxh6**

**32...Qd5 **
32...gxh6 33.Nxh6 Rg7 34.Qxf6+ Ke8 35.Qxe6+ Kf8 36.g3
White has 4 pawns and an ongoing attack for the rook.
The black knight on a5 is also completely out of play.
**33.Qb1 Qxd1+ 34.Qxd1 gxh6 35.h4 **

While Black managed to get 2 rooks for a queen and pawn,
he is objectively lost here as his rooks are terribly uncoordinated,
he has a number of weak pawns, his king is exposed,
and his knight is poorly placed. Skoberne grinds out the win from here.
**35...Kg7 36.e4 Nc4 37.Qc1 Kf8 38.Qxh6+ Ke7 39.Qg6 Ne5 40.Nxe5 fxe5 41.h5 Rh8 42.Qg5+ Kd6 43.Qe3 Rxh5 44.Qxb6+ Ke7 45.Qc7+ Kf6 46.Qd8+ Kg6 47.Qc8 Kf6 48.Qd8+ Kg6 49.Qg8+ Kf6 50.g4 Rg5 51.Qh8+ Kg6 52.Kf1 Rxg4 53.Qg8+ Rg7 54.Qxe6+ Kh7 55.Qxe5 R4g5 56.Qh2+ Kg8 57.Qb8+ Kh7 58.Ke2 Re7 59.Ke3 Rgg7 60.Qh2+ Kg8 61.Qd6 Rd7 62.Qe6+ Kh7 63.b6 Rb7 64.Qc6 Rbe7 65.Qb5 Rb7 66.Qh5+ Kg8 67.Qc5 Kh7 68.Qc6 Rbe7 69.Qd6 Rd7 70.Qh2+ Kg8 71.f4 Rg6 72.Qh3 Rgd6 73.Qg4+ Kh7 74.e5 1-0**

I had a pretty decent result at Kings Island back in November, only losing in the final round to my former Tennessee Tempo teammate Alex Shabalov. I'm not too satisfied with this game. I didn't really set him any difficult problems to solve and although I resisted a long time, I didn't manage to find my way to a draw. These kinds of losses are the ones I need to remove in order to get better.

This week's BCE position bears a lot of similarity to last week's. Again, it is a bishop versus pawns study by Reti (this time from 1923) that was cooked by Bondarevsky in 1955 and later repaired by Benko. However, there are a couple of new twists to the tale this time.

Unlike BCE-162, Benko included his correction in the revised BCE as Position 305.

This is Reti's position with all the pieces shifted one file to the right.
Now it really is a draw after
**1.Kg7! **
For some reason Benko inverted the starting moves with
1.e5? when Black wins with 1...fxe5! 2.Kg7 e4! 3.h6 e3! 4.h7 e2! 5.h8Q e1Q!
and Black will consolidate his extra piece.
**1...Bd3 2.e5! fxe5 **
2...dxe5 3.h6! Ke6
4.Kg8 Bc2 5.Kg7
with a positional draw was Reti's idea since Black can't advance his pawns without blocking the bishop's diagonal.
Benko's version also introduces a new theme into the position with
*3...Bh7 4.Kxh7 Kf7! 5.Kh8 e4 6.h7 e3 7.g5 fxg5 *stalemate
**3.h6! d5 **
The point of shifting the position is now revealed as the cook with Bh8
would now be Bi8, which is not on the board
**4.g5! d4 5.g6! Bxg6 6.Kxg6! d3! 7.h7! d2! 8.h8Q! d1Q! 9.Qxe5+ **
and a draw

Benko didn't stop there, and attempted to further improve the study. While still a draw, this version also has a few flaws.

**
1.g4 **
Benko gave 1.Kg7 a question mark because of 1...f5
but White still has a fantastic draw here with
2.exf5! d5 3.h4! d4 4.h5! Bxh5 5.f6! d3 6.g4! Be8
* (6...d2 7.gxh5! d1Q 8.f7!) *
7.g5! d2 8.g6! d1Q 9.f7! Qd7 10.Kg8 Qe6 11.Kg7!
**1...Kd8 **
1...Kd7 2.Kf8! Bg6 3.Kg7! Bxe4 4.Kxf6!
**2.h4! Ke7 3.h5! Bc6 4.e5! fxe5 5.h6! Be4! 6.g5 d5 7.Kg7 d4 8.g6! d3 9.h7! d2! 10.h8Q! Bc2! **
Benko concluded the study with 10...d1Q? 11.Qh4+! with a draw

because Black is losing his bishop.
However, the resulting Q+P vs Q+P ending is a win for White thanks to his far advanced g-pawn.
Shades of
Kasparov vs. The World!

In the 10th round, I lost yet another rook ending, this time to Walter Brown.
Note, this is not the 6-time US champion who spelled his last name with an e on the end.
Walter mostly stopped playing tournaments in the 1990s, but stilled stayed active
in chess as a TD for the CCA. We entered the rook ending after an exchange of
knights on c2 **42.Rxc2 **

**42...Rc8 **
Black could try to activate his rook along the f-file with
42...Rf8 when 43.Rf2 can lead to some interesting pawn endings.
43...Rxf2 44.Kxf2! Kc6 45.Ke3 Kc5 46.a3! d5 47.cxd5! Kxd5!

The engine says it is a draw, which goes against all I thought I knew
about pawn endings. It seems like White should be able to decoy with the
queenside pawns and then win on the kingside.
But because of the more active Black king,
White is unable to trade off all the queenside pawns,
so Black maintains the balance with his b-pawn.
A couple of sample lines 48.g4
* (48.h4 e4 49.g4 Ke5 50.g5 Kd5 51.a4 Kc5 52.Kxe4 Kb4 53.Ke5 Kxb3 54.Kf6 Kxa4 55.Kg7 b5 56.Kxh7 b4 57.h5 gxh5 58.g6 b3 59.g7 b2 60.g8Q b1Q+) *
48...g5 49.Kd3
* (*White actually loses with *49.h3? e4! 50.a4 Ke5! 51.b4 Kd5 52.a5 Kc4! 53.Kxe4 Kxb4) *49...e4+ 50.Ke3! Ke5 51.a4 Kd5 52.a5! Kc5 53.Kxe4! Kb4! 54.Kf5 Kxb3! 55.Kxg5 Kb4 56.Kh6 Kxa5! 57.Kxh7 b5! 58.g5 b4! 59.g6 b3! 60.g7 b2! 61.g8Q b1Q+!
and the queen ending with an h-pawn is drawn.

Instead of trading on f2, Black also has 43...Rf5 44.g4 Rf4 45.Rxf4 exf4

and it seems that there are a couple of ways White can make a drawn, but both just barely.
**a) **46.h4
Letting Black have a protected passed pawn is losing
*(46.Kf2? g5! 47.Kf3 Kc6! 48.Ke4 Kc5! 49.a3 b6 50.Kd3 d5!)*
46...h6 47.g5! hxg5! 48.hxg5! Ke6 49.Kf2 Kf5 50.b4! Kxg5 51.a4 Kf5 52.a5 d5
* (52...Ke6 53.b5! Kd7! *

and now White just waits with *54.Kf3 g5! 55.Kg4 *as the threat of a6 ties the Black king to the queenside*) *
53.b5! dxc4 54.a6! bxa6 55.bxa6! c3! 56.a7! c2! 57.a8Q! c1Q! 58.Qd5+! Kg4 59.Qd7+! * (59.Qg2+? Kh5 60.Qh3+ Kg5 61.Qg2+ Kf6 *and White is out of checks *62.Qh2) *
**b) **46.g5 Ke6 47.Kf2 Kf5 48.h4 Ke4 49.Ke2! f3+ 50.Kf2! b6 51.a4 Kd3 52.Kxf3! Kc3! 53.Ke4 Kxb3! 54.Kd3 and White has horizontal opposition 54...Kb4 55.Kd4! Kxa4 56.Ke4!

After that long digression, lets return to the game
**43.Rd2 Rc5 44.Kf2 **
White could hold up ...b5 with 44.a4 Ke6
but actually has to be a little careful as now the pawn ending after
45.Kf2 d5 46.cxd5+ Rxd5 47.Rxd5? * (47.Rc2) *47...Kxd5 48.Ke3 Kc5 49.Ke4 Kb4 is winning for Black!
**44...b5 45.cxb5 Rxb5 46.Ke3 Ke6 47.Rb2 Rc5 48.Kd3 **
It is simpler to get the passed pawns rolling with 48.b4 Rc3+ 49.Kd2 Ra3 50.b5 Kd7 51.Rc2
**48...d5 49.Rc2 **
Again, the passed pawns should be pushed.
49.b4 Rc1 50.b5 Kd7 51.b6 Kc8 52.a4 Ra1 53.Rb5
**49...e4+ 50.Kd2 Ra5 ** 50...Rb5 51.Rc8
**51.a4 d4 52.Rc6+ Ke5 53.Rc7 h5 54.Re7+ Kf5 55.Rd7 e3+ 56.Ke2 **
56.Kd3 Re5 **56...Ke5? ** 56...Ke4! 57.Re7+ Re5

**57.Re7+? **
57.Kd3! Rd5 58.Rc7!
puts Black in a lot of trouble.
His pawns are immobile While White's can run free.
Putting the rook on the c-file cuts off the Black king from the White pawns while the White rook can still help control Black's pawns from c4 or c2
58...Kd6 59.Rc4! * (59.Rc2 Rc5!) *
**57...Kd6 58.Re4 Rd5 59.Kd3 Kc5 60.Re8 Kb4 61.Rb8+ Ka3**

**62.a5? **
The e-pawn had to be kept under control with 62.Re8 Kxb3 63.a5 Rxa5
* (63...Kb4 64.a6 Rd7 65.a7 Rxa7 66.Kxd4) *
64.Kxd4= Ra2 65.Rxe3+
**62...Re5! 63.Ke2 d3+ 64.Ke1 Rc5 65.Kd1 e2+ **
65...Kb2 is a more immediate mate **66.Kd2 Re5 0-1**

Lessons from this ending: 1. Passed pawns must be pushed. I could have saved myself alot of trouble by getting the queenside pawns rolling. 2. Pawn endings are all about calculation. Relying on intuition can easily lead you astray. 3. Always maximize the utility of your pieces. The dual ideas of cutting off the Black king while simultaneously attacking/controlling the Black pawns with 58. Rc7! perfectly illustrate this theme.

The Hungarian theoreticians Peter Lukacs and Laszlo Hazai are long-time collaborators and contributors to the New In Chess Yearbook series. It is very rare to have an edition of the Yearbook without a survey by them in it and Volume 128 was no exception. While their surveys are always worthwhile, their examination of a variation in the anti-Berlin Ruy Lopez didn't fit in very well for my Olympiad series as there were no games played with the specific line they looked at. So for this post I selected a short game in the variation that featured a somewhat similar pawn structure and piece arrangement. This was Board 3 of the match between Azerbaijan and England with Arkady Naidiitsch as White against David Howell.

**
1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.d3 Bc5 5.Bxc6 **
5.c3 0-0 6.0-0 Re8 7.Nbd2 a6 8.Bxc6 dxc6 9.Nc4 was the survey variation
**5...dxc6 6.0-0 Qe7 7.Nbd2 Bg4 8.Nc4 Nd7 9.h3 Bh5 10.Bd2 f6 11.b4 **

This new move is Komodo's choice.
Deep Fritz and Stockfish prefer to prepare it with
11.a3 and 11.Rb1 respectively. None of the engines give White very much here.
**11...Bxb4 12.Bxb4 Qxb4 13.Rb1 Qe7 14.Rxb7 Nb6
15.Na5 0-0 16.Nxc6 Qc5 17.Nxa7 Qa3 18.Nc6 Qd6 19.Na7**

**19...Qa3 **
19...Na4 with the idea of Qa6 give Black a big edge.
White will have to struggle for a draw with 3 pawns for the piece.
Instead, Howell decides to repeat moves.
Note that 19...Nd7 isn't as good since
20. Nb5 Qa6 21. Rxc7 Qxb5 22. c4 forces the Black queen to abandon defense
of Nd7.
**20.Nc6 Qd6 21.Na7 Qa3?! ½-½**
I wonder if Howell would have played 21...Na4 if it wasn't a team event where
sometimes the strategy is to hold with Black and press with White. It didn't work
out well here as the Azeris swept the remaining boards to with 3.5:0.5.

I've posted my game with Gabriel Schwartzman from the penultimate round of the 1994 US Open to the GM games section. I was having a pretty good tournament with 7.5/10, just behind the leaders and was actually paired down in this game as Schwartzman was only at 7/10. I ended up in a pretty passive middle game position and tried to avoid creating further weaknesses. I was rewarded when he allowed me some exchanges that freed my position somewhat, but I almost immediately handed him back the advantage with an ill-timed pawn exchange. A very interesting queen and bishop ending arose, where I think Black may be drawing. However, in the game he kept the pressure on and I eventually blundered and lost.

Schwartzman was a chess prodigy. At the time, it was very rare to be a teenage grandmaster. However, it looks like he stopped playing chess in 2001.

One of the legendary chess composers is Richard Reti. I would expect most chess players to know his famous king and pawn study by the keymove (1.Kg7) alone. Reti was quite prolific with over 100 endgame studies to his name. Of course, composing that many studies in the pre-computer age means some of them would eventually get cooked. That is the case with BCE-162, which was one of several similar studies published in 1922. This one was cooked by Igor Bondarevsky in 1955. Benko did not include this position in the revised edition of BCE. However, Benko later corrected Reti's study by moving the starting postions of the kings.

**1.h4! **
1.Kd2? Bc6! 2.h4 Be8
**1...Kg2 2.Kd2! **
2.Kd3? Kf2 3.b5 Be2+
**2...Kg3 **
2...Kf2 3.b5 Be2 4.a6 bxa6 5.b6
**3.Ke3!**
Now we are back in the main line of Reti's study.
**3...Bg4 4.b5! Kxh4 5.b6! Bc8 6.Kf4 1-0**

Thus, the study is saved, but I didn't really like the unnatural starting position of the Black king on h1. It isn't really clear how the king would have ended up there in a game. I fooled around with the position a little and came up with the following alternatve.

I had some versions with a dark squared bishop for White, but I didn't think
they were fully satisfactory, so I settled on this one with the rook.
**1.Rc5! c1Q 2.Rxc1! Kxc1 3.Ke3! Kd1 **
3...Bb5 4.h4! Be8 5.Kd4!
**4.h4! Ke1 5.Ke4! **
5.Kf4? Kd2;
5.Kd4? Kf2 6.Kc5 Kg3 (6...Ke3 7.Kb6 Bf3! 8.b5
(8.h5 Bxh5! 9.Kxb7 Be2 10.a6 Kd4! 11.b5 * (11.a7 Kc4) *11...Bxb5! 12.a7 Kc5)
8...Kf4) 7.Kb6
**5...Kf2 **
5...Kd2 6.Kd4! Kc2 7.Kc5! Kd3 8.b5! Ke3
* (8...Ke4 9.a6! bxa6 10.b6! *
and the Black king is blocking the long diagonal*) *
9.a6! bxa6 10.b6! Bf3 11.h5! and wins
**6.Kd4 **
6.Kf4 also wins, which is a small flaw. I chose the text as the main line since
it transposes back to Reti's study.
**6...Kg3 7.Ke3! Bg4 8.b5! **
which is back to Reti's main line
**8...Kxh4 9. b6!**

Continuing my Olympiad/Yearbook 128 series, the next survey on the list was
by Robert Ris on the Fianchetto Benoni. While the variation examined by Ris was not
played in the Olympiad, the game between Boris Markoja of Slovenia and Daniel Dardha of
Belgium was an exciting game in another theoretically important line of the Fianchetto
Benoni.
**
1.d4 Nf6 2.c4 c5 3.d5 e6 4.Nc3 exd5 5.cxd5 d6 6.g3 g6 7.Bg2 Bg7 8.Nf3 0-0 9.0-0 Re8 10.Bf4 **

This position is getting a lot of scrutiny these days.
The
Quality Chess Grandmaster Repertoire series
has basically become the main line of theory in recent years.
There has been some back and forth in the Fianchetto Benoni.
Initially, Boris Avrukh recommended 10.Nd2 for White in
Volume 2.
Marian Petrov came up with some resources for Black in
Volume 12 on the Modern Benoni,
so Avrukh changed his recommendation to the bishop move in
Volume 1A.
**10...Ne4 **
Ris' survey explored 10...h6 but no one in the Olympiad went for this,
but the text is a very important line for the theory of this variation.
**11.Nxe4 Rxe4 12.Nd2 Rxf4!? **

Black sacrifices the exchange for a pawn,
gaining the bishop pair and a strong queenside pawn majority in the process.
However, White gets a strong central pawn position.
Petrov prefers 12...Rb4 with the idea that after 13.a3 Rxf4 14.gxf4 Bxb2
White has to put his rook on an awkward square. 15.Ra2.
Avrukh counters 12...Rb4 with 13.Rb1 which isn't examined by Petrov
13...g5!? 14.Be3 Bf5 15.a3 Rxb2 16.Rxb2 Bxb2 17.Qb3 is the main line from there
when the engines favor White, but the two games I found in the database were
both drawn.
The position definately needs further practical tests.
**13.gxf4 Bxb2 14.Rb1 Bg7 15.Nc4 **
Another crossroads where Petrov considers this position as better for White,
whereas Avrukh prefers 15.e4
**15...b6 **
Both Leko and Bologan played the immediate 15...Na6 here.
That may be more flexible as Black might sometimes be able to play ...b5 in one go.
**16.a4 **
16.Qa4 is more popular here, but there haven't been many games.
**16...Na6 17.e4 **The first new move.
Prohaszka-Paschell, Budapest 2009 saw the players duck the fight after
17.Re1 Nb4 18.e4 Ba6 19.Qb3 ½-½
**17...Nb4 18.e5 Ba6!? **
Sharpening the play. An alternative would be to precede this with
18...dxe5
**19.Nxd6 Bxf1 20.Kxf1 Qh4**

**21.Qf3 **
21.Nxf7!? is an interesting sacrifice to get the central pawns rolling
21...Kxf7 22.e6+ Kg8 23.d6 looks scary for Black.
**21...Rd8 22.Rd1 Rxd6 ** 22...Bh6 feels more consistent.
**23.exd6 Qd8 24.Re1 Bf6 25.Qe4 Qxd6 **

Again, time to take stock after an exchange sac.
Black still has a pawn, but now he lacks the bishop pair and his queenside pawns
aren't very mobile. The knight also seems a bit stranded on b4.
On the plus side, the White pawns are very weak and
Black's pawn structure is relatively solid.
Overall, White should have the edge, but is it enough to win?
**26.h3 Kg7 27.f5 a6 28.fxg6 hxg6 29.h4 Qh2 30.Re3 b5 **
grabbing the h-pawn looks too dangerous as it lets the d-pawn run free 30...Qxh4 31.Qxh4 Bxh4 32.d6
**31.axb5 axb5 32.Qe8 Nc2 **
The cold-blooded engine says Black should grab the pawn now
32...Qxh4 33.d6 * (33.Rh3 Qc4+ 34.Kg1 Qc1+) *33...Qd4 with equality
**33.Rg3 Bxh4 34.Rf3 Qc7 35.d6 Qa7 36.Qe5+ f6 37.Qe7+ Qxe7 38.dxe7 Kf7**

**39.Rc3 ** 39.Rh3! provokes 39...g5
which fatally weakens the e8-h5 diagonal
40.Rc3 Nb4 41.Re3 Ke8 42.Bf3 and White wins
**39...Nb4 40.Rxc5 Kxe7 41.Be4 f5 42.Rxb5 Na6 **
Black has an immediate draw with 42...fxe4 43.Rxb4=
**43.Rb7+ Kf6 44.Rb6+ Kg5 45.Bxf5 **
Black should also hold the draw after 45.Bc6 Nc5 46.Be8 Nd3 47.Rxg6+ Kf4
**45...Kxf5 46.Rxa6**

**46...g5? **
Dvoretsky
opens his section on Rook and Pawn vs. Bishop and Pawn with a blue section
(those are the most important ones) that begins
One should not protect the pawn by placing it on a square of the bishop's color.
Almost all of these postions are lost.

The current game is no exception.
Instead, Black should set up a barrier with 46...Bf6
when his fortress cannot be taken
**47.Rh6 Kf4 48.Kg2 Kg4 49.Rh8 Kf4 50.Rf8+ Kg4 51.f3+ Kh5 52.Re8 Kg6 53.Kh3 Bf2 54.Kg4 Bc5 55.Re5 Bd4 56.Rxg5+ Kf6 57.Rb5 Be3 58.f4 Kg6 59.Kf3 1-0**

Happy New Year! Looking at my backlog of BCE corrections, I should be able to keep posting a postion each Wednesday well into 2019, including many triple plays of back-to-back-to-back posts with a common theme. This week I'll complete the troika of positions featuring the first World Champion, Wilhelm Steinitz. Today's example comes from his 1866 match with Adolf Anderssen.

There is some debate if this was a world championship match. Fine calls it such, but the general consenus seems to be that the title did not come into being until 20 years later when Steinitz beat Zukertort. However, these were 2 of the top players of the day. In August 1866 when the match finished, Sonas has Steinitz as #2 and Anderssen as #4. The difficulty in rating players from that era, is that there weren't many international competitions. The rest of Sonas' list consists of players I have never heard of: #1 Berthold Suhle, #3 Cecil de Vere, #5 Hans von Minckwitz, #6 Philipp Hirschfeld and #7 Gustavus Reichhelm. Maybe I'll look into the games of these players at some time in the future. I did find that Shule drubbed Hirschfeld +7 -0 =2 in an 1865 match, which may account for his top rated position.

The Anderssen-Steinitz match was a crazy match by the standards of any era. After a game one loss, Steinitz came back with 4 straight wins. Undaunted, Anderssen hit back with 4 consecutive wins of his own. Then, Steinitz took back over winning 4 of the last 5 to take the match 8-6 with no draws!!

The BCE position comes from the 3rd game. After **40. Nb5** Steinitz launched a
combination that led to a pawn up knight ending.

**40...Re6 41.Qxg6+ Rxg6 42.Nxa7 Rxg2+ 43.Kh1 Rxh2+ 44.Kxh2 Nf3+ 45.Kg2 Nxe1+**

**46.Kf1! Nd3 **
Since Fine's defense relied on playing f3, I thought 46...Nf3!?
was an interesting try to prevent that,
but White is just in time with
47.Kg2 * (47.Nc6 Kg6! 48.Kg2 Nh4+ 49.Kf1 Kf5 50.Ke2 Ke4) *
47...Nh4+ 48.Kf1 f3 49.Ke1 Kg6 50.Kd2 Ng2 51.Kd3 Kg5
* (51...Kf5 52.Nb5) *
52.Nc6 Kh4 53.Nd4 Kxh3 54.Nxf3! and holds
**47.Nc6 Kg6 48.Ke2 Nc5 49.Kf3 **reaching the starting point of BCE-129.

Incredibly, Fine had to defend this very ending a few years after the publication
of BCE in his match with Miguel Najdorf in 1949. I hadn't previously known about this match
between two of the top players in the Americas at the time. Fine won the first two
games of the eight game match, but Najdorf won the next two and the final four were drawn.
The third game was the only one in which Fine opened with 1. e4, but Najdorf did
not try for his namesake variation and answered 1...e5. The knight ending was reached
after **44. Kxe2**

There are numerous conflicting stories about possible side wagers between the
players on the outcome of this
endgame. Don Miguel was a great storyteller, but there is probably truth
somewhere in all the stories.**44...Kf6 45.Nd6 Ke6** My database gave this move as 45...Ke5, which simply
drops the f7 pawn. I checked some other databases online and they also had 45...Ke5.
Finally, I found a printed game score in
the February 1949 issue of the Swedish magazine Tidskrift för Schack
which has the move 45...Ke6. I assume the move was incorrectly keyed into a database originally
and the error has been copied ever since. I don't really know how to correct something like that.
**46.Nc4+ Kd5 47.Nb2 Kd4 48.Nd3 f5 49.Nb4 Nf4+ 50.Kd2! **
50.Kf2? Nd3+ is a winning pawn ending for Black
**50...Ne6 51.Nc6+ Kd5 52.Ne7+! **
White's knight gets on a bad track after
52.Nb4+? Kc4! 53.Nc2 f4!
now the knight can't go too far afield because of ...Nd4
so the White king eventually has to give ground
54.Ne1 (54.Na3+ Kb3 55.Nb5 (55.Nc2 Ng5 56.Ne1 Kc4! 57.Ke2 Ne6! 58.Kd2 g5 59.Kc2 h5 60.Kd2 Nd4 61.h3 * (61.Kd1 Kc3) *61...h4 62.Kd1 Kc3 63.Kc1 Ne2+ 64.Kd1 Ng1) 55...Kb4) 54...g5 55.Kc2
**52...Ke5 53.Ke3 Kf6 54.Nd5+ Kg5 55.Kf2 Kh4 56.Kg2 g6 57.Ne7 Kg5 58.Kg3 f4+ 59.Kf2 Nd4 60.Nd5 Nc6 61.Nc3 Kh4 62.Kg2 Ne7 63.Ne4 Nf5 64.h3? **

Ironically, establishing the pawn formation he recommended for Anderssen turns out
to be the losing move. Numerous annotators have pointed out that 64.Nf2 would allow White to hold the draw
The Tidskrift för Schack version of the wager story is that Fine offered a draw here,
which Najdorf countered with an offer of a $200 bet that was met with silence.
**64...Ne3+! **
Heading for e1, this move gains a crucial tempo versus the other route
64...Nd4? 65.Nf2 Nc2 66.Nd3! and White holds
**65.Kh2 Nc2 66.Kg2 Ne1+ 67.Kf2 Kxh3 68.Kxe1 Kg2! 69.Ke2 **
Edward Lasker's suggested 69.Nd6 sets the trap 69...Kxf3?
* (*Black wins similar to the game by rolling the h-pawn *69...h5)
*70.Nf7 h5 * (70...g5 71.Nxh6 Kg3 72.Nf7 g4 73.Ne5 f3 74.Nxg4) *
71.Ne5+ Kg2 72.Nxg6 f3 73.Nh4+ Kg3 74.Nxf3 Kxf3 75.Kf1 =
**69...h5 70.Ng5 h4! 71.Ne6 g5 0-1**
Black wins the pawn ending after 72.Nxg5 h3 73.Nxh3 Kxh3 74.Kd3 Kg2! *
74...Kg3?? 75.Ke4 +- * 75.Ke2 Kg3-+
