6/29/05 - Airapetian-Bereolos, 2005 Chicago Open

In the final round, I had the Black pieces against Chouchanik Airapetian 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 d6 8. c3 O-O 9. h3 Bb7 10. d4 Re8 11. Ng5 Rf8 12. Nf3 h6 Given how things had gone the last couple of rounds, perhaps 12... Re8 and a quick handshake was called for. Instead, I decided to try to fight for an even score in the tournament. 13. Nbd2 Re8 14. Nf1 Bf8 15. Ng3 Qd7 The main line is the immediate 15... Na5 16. Bc2 Nc4 16. Nh4 Na5

17. Bc2 It appears that White can take advantage of Black's move order with 17. dxe5 dxe5 18. Nh5 as in the game Westerinen-Johansen, Gausdal 2002. One pretty variation is 18...Qc6 19. Qf3 Be7 (Johansen played 19...Nxb3) 20. Nf5 Nxh5 21. Bxf7+ Kxf7 22. Nxh6+ Ke6 23. Qf5+ Kd6 24. Nf7+ Kc5 25. Be3+ Kc4 26. Nxe5# 17... g6?! I end up suffering a long time for this move It was much better to play 17... Nc4 when the knight will be much more active from b6 than it ends up in the game. 18. b3 Nc6 19. d5 Ne7 The knight ends up passive here for a long time. Afterwards, my opponent suggested 19... Nd8 with the idea Bc8 and Nb7-c5, but that doesn't look that appealing to me either. On e7 the knight helps defend the kingside and may assist with an ...f5 break in the distant future. 20. c4 c6 20... c5 here or on the next move with a closed Benoni structure is another option, but I think it is best to open the file in order to trade major pieces and ease Black's cramped position. 21. Be3 Qc7 22. Qd2 cxd5 23. cxd5 Kh7 24. Rac1 Qd8 25. Nf3 Nd7 26. Bb1 Rc8 27. h4 Nf6 28. Nh2 Qd7 29. Bd3 Rxc1 30. Rxc1 Rc8 31. Be2 Nfg8 Better is 31... h5. However, I was still dreaming about playing ...f5 some day which is pretty much out of the question in conjunction with ...h5. 32. h5 Rxc1+ 33. Qxc1 Qc8 34. Qd1 Qc3 35. Ng4 White really has done much to increase her advantage over the past twenty moves, but I can't say that Black has equalized either. Now, I finally lost patience and lashed out with the clocks running down. 35... gxh5?! 36. Nxh5 f5 At long last, but at this point it only exposes the Black king 37. exf5 Nxd5 38. f6 Qc7 better is 38... Nxe3 39. fxe3 but White still has a clear advantage. 39. Qb1+ I had missed the check along the diagonal. 39... Kh8 40. Qg6 Nxe3 41. Nxe3 d5 42. Qe8 d4 43. Qxf8 dxe3 44. f7 exf2+ 45. Kh2 e4+ 46. g3 f1=N+ 47. Bxf1 Qc2+ 48. Bg2 [1:0]

6/26/05 - Bereolos-Pasalic, 2005 Chicago Open

On Monday morning, I had the White pieces vs. Mehmed Pasalic, who had beaten me in the final round last year in a one-sided game. I was hoping to improve on that, but it turned out not to be the case. 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. f4 c5 6. d5 O-O 7. Nf3 e6 8. Be2 exd5 9. cxd5 Nbd7 10. O-O I think this solid move gives white a plus. The main alternative is the wild line 10. e5 dxe5 11. fxe5 Ng4 12. e6 Nde5 10... Re8 11. Nd2 a6 12. a4 Qc7 13. Kh1 Rb8 White has a huge plus score in the database with a variety of moves including my choice 14. a5 b5

This was a bit disconcerting. For the second game in a row my opponent plays a move which I thought I had just prevented. 15. axb6 Nxb6! In earlier games Black had played 15... Rxb6 when the White knight comes to c4 with tempo. 16. Ra3 16. Bxa6? Ra8 is the tactical justification for capturing with the knight. 16... c4 Now I think Black is fine. The white center is well restrained and he has clear ideas of doubling rooks on the e-file as well as Nf6-d7-c5, perhaps in conjunction with ...f5. 17. Re1?! I found two games that reached this position by transposition, and in both cases White won after 17. Bf3 which seems a much superior move to the text since it isn't really clear that the rook belongs on e1 where it might become subject to tactics on the e-file. White might then be able to start to make Black think about his c-pawn with Qc2 and Na4, which aren't immediately available: 17. Qc2 Nfxd5; 17. Na4 Nxe4 17... Bb7 18. Bf3 18. Qc2 Re7 looks quite comfortable for Black as well. 18... Nfd7 Another drawback of Re1 is that Nd3 arrives with a tempo. I now try a rather desperate pawn sacrifice, but never manage to generate realistic threats, but it is hard to suggest improvements, basically this a dream Benoni position for Black 19. e5 dxe5 20. d6 Qxd6 21. Bxb7 Rxb7 22. Qf3 Rbb8 23. Nce4 Qe6 24. Ng5 Qd5 25. Qxd5 Nxd5 26. Nxc4 exf4 27. Rd1 N7f6 28. Nd6 Re2 29. h3 Ne3 30. Bxe3 fxe3 31. Rxa6 Rexb2 32. Nc4 Rb1 33. Nxe3 Nd5 [0:1]

6/22/05 - Becerra-Bereolos, 2005 Chicago Open

After that difficult game, I got the Black pieces against another tough opponent in the evening round, GM Julio Becerra. 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 d6 8. c3 O-O 9. d4 Bg4 10. d5 Na5 11. Bc2 Qc8 12. Nbd2 c6 13. b4 Nc4 13... Nb7 is the other main move here when the knight can come back into play via d8 and e6. 14. Nxc4 bxc4 15. dxc6 Qxc6 16. a4 h6 16... a5!? is a double-edged try here. Black gives White a protected passed pawn in exchange for the c5 square for his knight. 17. a5!? This seems to be Becerra's new idea in this position. A few days after this game I received the June 2005 issue of Chess Life which had the game Becerra-Goldin (1-0) from the US Amateur Team Championship. The position seems pretty balanced, but Black has to figure out what squares to develop his pieces to. 17... Rfd8 17... Rfe8? 18. Ba4 is one point of White's move The immediate 17... Qb7 was Goldin's choice. 18. h3 Be6 19. Qe2 Nd7 19... Rac8 20. Bd2 Qb7 21. Rad1 Bf8 transposes to Becerra-Goldin, where Julio played 22. Nh2 but 22. Nh4 similar to the present game, looks stronger. My thought was that b5 might be a good square for my knight via b8-c6-a7, but it isn't clear that is a good plan. On f6 the knight could help support a d5 break as well as keeping an extra defender on the kingside. 20. Bd2 Qb7 21. Rad1 Bf8 22. Bc1 Rac8 23. Nh4 g6 I wanted to keep the knight out of f5.

24. Nf5! d5 The sacrifice cannot be accepted 24... gxf5 25. exf5 Bd5 26. Qg4+ Kh8 27. Qh4 and White's attack is winning 25. Nxh6+ Kh7 25... Bxh6 26. Bxh6 d4 had to be played when White is much better. Instead, the floodgates are opened and the White pieces pour in. 26. exd5 Bxd5 27. Qh5 Nf6 28. Qh4 Bxg2 29. Ng4+ [1:0]

6/21/05 - Bereolos-Finegold, 2005 Chicago Open

In round 4, I had the White pieces against IM Ben Finegold. In our 1999 game at this tournament, I obtained a very good position and he played a rather dubious queen sacrifice in an attempt to cause chaos. Well, that worked as I lost my head in a time scramble and lost. This game had some eerie similarities to that one. 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. f4 O-O 6. Nf3 Na6 7. Be2 In recent years I have been playing 7. e5 in this position. However, after the miserable position I got in the opening against Chris Mabe at Land of the Sky, I decided to revert to this more solid move. Unfortunately, I spent too much time remembering the subtlties of this variation and it came back to hurt me later. 7... e5 8. fxe5 dxe5 9. d5 Nc5 9... c6 used to be automatic here. Then, Kasparov played the text against Lautier at Amsterdam in 1995 and now it has become the main move. 10. Bg5 I fell into the trap 10. Qc2? Nfxe4 with clear advantage to Black against Doug Hyatt in the 1999 Space City Open. 10... h6 11. Bxf6 Qxf6 12. b4 Na6 13. a3 c5 14. Rb1 In the 1999 Chicago Open, in the round after Ben sacrificed his queen for "nothing" and beat me, I got the inspiration to play the speculative 14. b5 Nc7 15. d6 Rd8 16. dxc7 against Ryan Porter. Alas, I was only strong enough to draw that game. 14... Bd7 The good thing about players following the example of Kasparov is that on very rare occasions he made mistakes, so you can catch someone with an improvement. 15. d6 A big improvement on Lautier's 15. b5 Nc7 16. d6 Ne6 and the knight finds a nice home on d4.] 15... Rfd8 Now Black's queenside gets bottled up, but after 15... Rad8 16. O-O Be8 (16... Bc8 17. Nb5) 17. b5 Nb8 Black's kingside is in tangles. 16. b5 Nb8 17. Qd5 Bc8 18. Qxc5 18. Rd1 Bf8 19. Qxe5 also deserves attention 18... Be6 18... Qxd6 19. Qxd6 Rxd6 20. c5 Rd7 21. Nd5 and White is clearly better 19. Nd5 19. O-O b6 (19... Nd7 20. Qe3) 20. Qc7] 19... Bxd5 20. Qxd5 Nd7 20... Qxd6 21. Qxb7 Nd7 22. Rd1± 21. c5 I didn't want to let his knight get an outpost after 21. Qxb7 Nc5 but 21. O-O looks more accurate here, now Black generates counterplay 21... Rac8 22. Rc1 Qf4 23. Rc3 Played after long thought. I didn't like the looks of letting his queen into e3, but White still might have the advantage after 23. Nd2 Qe3 24. Nb3 Nf6 23... Nf6 24. Qxb7 Qxe4 25. c6 Qb1+ 26. Bd1 Qe4+ 27. Be2 Bf8? Probably due to my time situation he rejected the repetition with 27... Qb1+= 28. Rc4 28. Rd3 denying the check on b1 is probably a bit cleaner, but the text is also strong. 28... Qe3? this should lose, but after 28... Qb1+ 29. Kf2 Ne4+ (29... Qxh1 30. Nxe5 Nd7 31. cxd7 (31. Nxd7)) 30. Rxe4 Qxe4 31. Rd1 White is much better. 29. c7 Re8 30. Qc6 Bxd6 31. Qxd6 Ne4 32. Qc6 Qf2+ 33. Kd1 Ng5

34. Qxe8+? Horrifying. For some reason I hallucinated that this was winning an entire rook. The game would soon be over after 34. Nxg5 hxg5 35. Bg4 but not (35. Rf1? Red8+ 36. cxd8=Q+ Rxd8+ 37. Kc1 Qe3+ 38. Kb1 (38. Kb2 Qxe2+ 39. Rc2 Qxf1) 38... Qb3+ =) 34... Rxe8 35. c8=Q Rxc8 now I suddenly realized I had no queen. However, White should still be winning, but now it is much more difficult. 36. Rxc8+ Kg7 37. Nxg5 37. Rf1 is more accurate 37... hxg5 38. Rf1 Qd4+ 39. Kc2 f5 40. Rc7+ Kh6 41. Rc4? A mistake dropping a pawn immediately after the time control had passed. After 41. Bc4 White is still relatively coordinated could still hope to advance his queenside pawn majority with the assistance of his king, rook, and bishop 41... Qe3 42. Kd1 Qxa3 43. Rf3 all of White's winning chances seem to slip away now. Perhaps 43. g3 was still a try. 43... Qa1+ 44. Rc1 Qd4+ 45. Kc2 g4 46. Rg3 e4 47. Kb3?! 47. Rf1 e3 48. Rd1 Qa4+ with a draw was a better way to end the game. Now, Black actually gets some winning chances. 47... f4 48. Rgc3 f3 49. gxf3 gxf3 50. Bxf3 exf3 51. Rf1 f2 52. Kc2 Qd5 53. Rh3+ Kg7 [53... Kg5!?] 54. Rd3 Qg2 54... Qxb5 55. Kd2 Qg5+ 56. Re3 Qg2 57. Ke2 Qxh2 is a superior try since he actually gets the b-pawn, but I think White still holds without much problem. Black's problem is that he has a rook pawn on the queenside so after White sacrifices his rooks for the queen and g-pawn the pawn ending is a draw. 55. Rdd1 Qxh2 56. Rd2 Qf4 57. Rdxf2 Qc4+ 58. Kd2 g5 58... Qxb5 59. Rf7+ Kh6 60. Rh1+ Kg5 61. Rg1+= 59. Rg1 Qd4+ 59... Qxb5 60. Rfg2 and Rxg5 if he does anything besides check. Now he tries various maneuvers with his queen attempting to capture the b-pawn with check, but I defend accurately. 60. Ke2 Qe4+ 61. Kd2 Qd5+ 62. Ke1 Qe5+ 63. Kd2 Qb2+ 64. Ke3 Qb3+ 65. Kd2 Qb4+ 66. Ke3 Qc5+ 67. Kf3 Qc3+ 68. Ke2 Qc2+ 69. Ke3 Qb3+ 70. Kd2 Qa2+ 71. Ke3 Qa3+ 72. Ke2 Qa2+ 73. Ke3 Qe6+ 74. Kd2 Qd6+ 75. Ke2 Qe5+ 76. Kd2 Qd4+ [½:½]

6/20/05 - Smith-Bereolos, 2005 Chicago Open

In the evening round, I had the Black pieces against Erickson Smith. 1. f4 g6 2. e4 Bg7 3. d4 d6 4. Nf3 Nf6 5. Bd3 5. Nc3 would transpose to a Pirc 5... O-O 6. O-O c5 7. c3 7. dxc5 deserves serious consideration 7... Qb6 8. Qe2 Nc6 I think 8... cxd4 is a bit more accurate when Black has no problems at all, although the text doesn't really trouble Black either. 9. dxc5 Qxc5+ 10. Be3 Qa5 10... Qh5 discouraging a kingside attack also deserves attention 11. h3 Bd7 12. Nbd2 Qc7 13. Qf2 b5 14. Rac1 14. Bxb5 Qb7 15. Qe2 a6 and Black will regain either the e- or b-pawn with a better game 14... Qb7 15. Qh4 Na5 This is really inviting white to attack the king. Better is the immediate 15... Rfc8 letting the knight keep an eye on e5 for the time being. Since the b-pawn becomes sensitive later, 15... a6 or 15... b4 could be considered. 16. f5 16. e5 Nd5 17. Be4 is another good way to pursue the attack. 16... Rfc8 17. e5 This was somewhat unexpected, allowing my queen into the game. 17. Bh6 seems like a more natural way to pursue the attack. 17... dxe5 18. Nxe5 Qd5 19. Bd4 19. Nxd7 Qxd3 19... Nc6 20. Nxd7 20. Nxc6 Bxc6 and Black is fine 20... Nxd4 On the basis of the next variation, 20... Nxd7 needs to be played with only a slight advantage to white. 21. fxg6 hxg6 The critical position

22. Qxd4 It appears that White can gain the edge with 22. Nxf6+ Bxf6 23. Qe4 ( the attempt to gain two pieces for a rook with 23. Rxf6 fails because after 23... exf6 the c3-pawn is pinned) and Black has difficulties because of his weak b-pawn and White's looming Ne4 for example 23... Qg5 (23... Qxe4 24. Nxe4 (24. Bxe4? Ne2+) 24... Ne6 25. Nxf6+ exf6 26. Bxb5) 24. Qe1 Qc5 (24... Nc6 25. Ne4 Qd5 26. Qe2; 24... Ne6 25. Ne4) 25. Kh1 Nc6 (25... Nf5 26. Ne4) 26. Ne4 in all cases with a comfortable advantage to White 22... Qxd4+ 23. cxd4 Nxd7 24. Nf3 a6 25. Be4 Bh6 I really liked this move taking control of the c-file. 26. Rxc8+ with a draw offer, which I declined. While the position is objectively equal, it is easier to play Black because of the open file and better pawn structure. 26... Rxc8 27. Kf2 Nf6 28. Bd3 Nd5 29. Re1 e6 30. a4? a time pressure error. 30. g3 keeps Black's advantage to a minimum. 30... Nb4 31. Bf1 bxa4 32. Ne5 Nc2 33. Bxa6 Ra8 34. Re2 Be3+ 35. Rxe3 Nxe3 36. Be2 Nf5 37. Bf3 Rb8 38. Nd3 Rxb2+ [0:1]

6/15/05 - Bereolos-Fishbein, 2005 Chicago Open

In round 2, I had the White pieces against GM Alexander Fishbein 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. f4 O-O 6. Nf3 a6 7. a3 Once again trying Vaisser's suggestion, as I did a couple of years ago against Wojtkiewicz. Looking back on my notes to that game, I wasn't all that satisfied with the result of the opening, and the same is true of this game. Perhaps 7. Bd3, as Matthew Marsh played against me in the 2003 Knoxville City Championship deserves a chance. 7... b6 8. Bd3 c5 9. d5 b5 10. O-O Afterwards, he suggested the immediate push 10. e5 White could also try the Benko Gambit-like position after 10. cxb5 axb5 11. Nxb5 (11. Bxb5 Nxe4 is a standard equalizing tactic) This is an interesting position. White will probably have to lose a tempo retreating Nb5-c3 and a3 has weakened the b3 square. On the other hand, with f4 already in White is much further along in the center than he typically is in the Benko and Black spent two moves to play b5. 10... bxc4 11. Bxc4 Nbd7 12. e5 I chose to go for rather murky complications rather than 12. a4 Nb6 13. Bd3 a5 when I thought Black was fine. 12... dxe5 13. fxe5 Ng4 14. e6 fxe6 15. h3?! Now Black gains a nice edge. The standard ploy of 15. Ng5 doesn't work out so well in this position after 15... Bd4+; Best seems to be 15. dxe6 to meet 15... Nde5 with 16. Bd5 15... Nde5 16. Nxe5 Rxf1+ A good intermezzo either diverting a White piece from d5 or forcing the awkward 17. Kxf1. If instead, 16... Nxe5 white plays the in between 17. Rxf8+ 17. Qxf1 Nxe5 18. Ba2 Since White trades the light squared bishop on the next move anyway, it was better to start activating the undeveloped queenside with 18. Be3 18... c4 19. Bxc4 This maintains material equality, but now Black's unopposed light squared bishop becomes a monster. 19... Qb6+ 20. Kh1 Nxc4 21. Qxc4 Bb7 22. Bg5 Rc8 on 22... Qxb2 my intention was 23. Rb1 but 23... Bxd5 looks very good for Black. He decided to try to avoid complications and just play on his positional trumps. 23. Qg4 Rf8?! 23... Qxb2 is still good. The Black king is a bit open, after 24. Rb1 Qxc3 25. Rxb7 Qe1+ 26. Kh2 Be5+ 27. Bf4 Bxf4+ 28. Qxf4 exd5 but it certainly isn't two pawns worth of compensation.

24. Bxe7? Remarkably, White has a resource here 24. Qxe6+ Qxe6 25. dxe6 Rf2 looks horrific, but 26. Rd1! seems to give White a realistic chance to hold the game, for example 26. Rd1 h6 (26... Bf8 27. Nd5) 27. Bxe7 Rxg2 28. Rd8+ Kh7 29. Rd7 Bc6 30. Rd6 Bf3 31. Rd3 with a repetition. 24... Rf5 25. Rd1 25. d6 Qxb2 26. Rd1 Bxc3 27. d7 Ba5 28. d8=Q+ Bxd8 29. Rxd8+ Kg7 and the opposite colored bishops work in Black's favor. 25... exd5 26. Bh4 d4 27. Ne2 27. Ne4 is nominally better, but Black is still winning. The text allows a nice finish. 27... h5 28. Qg3 Be5 29. Qd3 Qc6 30. Rg1 Rf1 31. Qb3+ Kh8 Moving the king to the 7th rank would allow Qxb7 with check followed by Rxf1 and White can grovel a little longer. [0:1]

6/13/05 - Emory Castle Grand Prix

I'm still working on my analysis of Chicago Open games, but I jumped back on the tournament horse last weekend in Atlanta. I had a pretty solid result in the tough Premier section going 3-2, losing only to GM Serper and WGM Zatonskih. I'll present some highlights and lowlights after I clear my backlog from Chicago.

6/8/05 - Heiser-Bereolos, 2005 Chicago Open

In the opening round, I had Black versus Eric Heiser. 1. c4 g6 2. Nc3 Bg7 3. g3 Nf6 4. Bg2 O-O 5. e4 d6 6. Nge2 e5 7. O-O Be6 8. d3 Qd7 9. b3 This seems a bit slow 9. f4 is a more normal plan, but he plays to avoid that move. 9... Bh3 10. f3 Again, I prefer 10. f4 but understand the text. He doesn't want Be3 to get harassed by Ng4 10... Bxg2 11. Kxg2 Nc6 12. Be3 h6 13. Qd2 Kh7 14. Rfd1?! Even if he doesn't intend f4, this still seems like the wrong rook. Better is 14. Rad1 taking the queens rook off of the long diagonal and maintaining the kings rook as a defender of f3, which is the square I now aim for. 14... Ng8 15. d4 f5 16. d5 Locking the center initiates a typical Kings Indian scenario with attacks on opposite flanks. Normally, the absence of the light-squared bishop hurts Black in these types of positions, but with the White pawn structure of g3 and f3, there are plenty of hooks to pry things open without the light-squared bishop. 16... Nce7 17. b4 Nf6 18. c5 g5 19. Rac1 f4 20. Bg1 g4 21. Rf1 admitting the mistake of move 14, but in these types of positions, two tempi can be enormous. 21... Ng6 22. Kh1 Nh5 23. gxf4 exf4 Optically, it might look nice to plant a knight on f4 with 23... Nhxf4 but I didn't see any concrete follow up. It seemed to me that the pawn on f4 was doing a very good job of restraining the White pieces and this offset giving White access to d4. 24. Nd4 24. fxg4 Qxg4 doesn't seem to slow black down either 24... Bxd4 25. Bxd4 g3 Now it is clear that the race has gone very much in Black's favor. The Black pieces are pouring into the attack, and White hasn't many any inroads on the queenside. 26. cxd6 cxd6 27. Qe2 Nh4 28. Rfd1 Qh3

A pleasing lineup along the h-file 29. Rd3 g2+ 29... gxh2? 30. Qxh2 and Black doesn't have a good follow-up] 30. Kg1 Ng3 31. Qf2 31. hxg3 fxg3 and mate next move 31... Nf1 32. Rxf1 gxf1=Q+ 33. Qxf1 Rg8+ 34. Kf2 Qxh2+ 35. Ke1 Ng2+ 36. Kd1 Ne3+ 37. Bxe3 fxe3 38. Ne2 Qf2 [0:1]

6/2/05 - 2005 Chicago Open

I'm back from a very strong (26 GMs and 9 IMs in the 82 player Open section) and very difficult (I had the worst score I've ever had in this event, -2) Chicago Open. Everything was going fine for me until around 4 PM Sunday afternoon. At that point I had 2/3 and was a piece up against IM Finegold. The only trouble was that I had less than a minute to make around 8 moves. Suddenly, I hallucinated that I was winning a whole rook, when in fact I was only winning 2 rooks for a queen. While I still had a material advantage, the position was no longer a simple win, if it was a win at all. I ended up struggling to draw that game. After that, the wheels fell off and for the first time in a very long time, I lost my last 3 games. I'll probably post the complete game scores, since I obviously need a good analytical workout, but will probably take more time than usual since I want to go over these games pretty thoroughly.
