1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.cxd5 Nxd5 5.e4 Nxc3 6.bxc3 Bg7 7.Be3 c5 8.Qd2 Qa5 9.Rb1 cxd4 10.cxd4 Qxd2+ 11.Kxd2 0-0 12.Bd3 Rd8 13.Nf3 Nc6 14.d5 Na5 15.Ke2 b6 16.Bg5 f5 17.Bxe7 fxe4 18.Bxe4 Ba6+ 19.Kd1 Rd7 20.d6 Bb7

21.Nd2 So far we had been following the 7th game of the Speelman-Short 1991 Candidates match, which was drawn after 21.Bd3 Bf6 22.Bb5 Bc6 23.Re1 Bxe7 24.Rxe7 Rxd6+ 25.Ke2 Bxb5+ 26.Rxb5 Nc6 27.Re4 Rad8 1/2-1/2. Engines in 2020 suggest that 21.Re1 is White's best, but it should all be equal. 21...Bf8 22.Bxf8 Beginning a sequence of exchanges that only helps Black improve his worst placed pieces (Ra8 and Na5). Better was 22.Re1 22...Rxf8 23.Bxb7?! Black starts to take over after this move. There is no need for White to initiate this exchange. Instead, White should be comfortable after 23.f3 but I probably started seeing ghosts in lines like 23...Rxd6 24.Ke2 Ba6+ 25.Ke3 Rfd8 26.Nb3 Nc4+ but the White King is quite safe after 27.Kf4 23...Nxb7 24.f3 Rxd6 25.Rb2 Nc5 26.Kc2? White's pieces are stepping on each others toes after this move. White is still in the game with 26.Rc2 Nd3 27.Ke2 Re8+ 28.Ne4 Nc5 29.Rc4

26...Re8 It looks like Black missed a forced win with 26...Na4 27.Rb4 Rc8+ 28.Kd1 Nc3+ 29.Ke1 Re8+ 30.Ne4 Rd1+ 31.Kf2 Rxe4] 27.Kb1 Rde6 28.Rc2 Re2 29.g3 R8e3 30.Ne4?! Trying to bail out into a pawn down rook ending, but White's rook is too passive. I should have tried something like 30.h4 but the White position is pretty lousy at this point. 30...Rxc2 31.Kxc2 Nxe4 32.fxe4 Rxe4

33.Rd1 activating the rook, but it costs another pawn It would be better to make Black demonstrate his technique with 33.Kd3 Ra4 34.Ra1 33...Re2+ 34.Kb3 Rxh2 35.Rd8+ Kg7 36.Rd7+ Kh6 37.Rxa7 Rg2 picking up the g3 pawn, the rest needs no comment. 38.Kc4 Rxg3 39.Kb5 g5 40.Kxb6 g4 41.Kc5 Rd3 42.a4 g3 43.Ra8 Kg5 44.a5 Kh4 45.Kc4 g2 46.Rh8 h5 0-1
