Chicago Open Games centralized knight is superior White's bishop.] 18...Qd8? [18...Nxe4? is bad because of 19.Bxf7+ Kh8 (19...Qxf7 20.Nh6+; 19...Kxf7 20.Nh6+ Ke7 21.Qxe4++−) 20.Bxg6 hxg6 21.Qh3+ Kg8 22.Nh6++−; however 18...Rxe4! was strong. 19.Nxg7! and now Black can play astounding 19...Nf4!! To be honest, I didn't see this move during a game and when it was first pointed to me by Fritz I thought that it refutes the whole combination. I immediately called Alex and asked his opinion about this position. I was surprised again when Alex told me that he actually saw this move during the game!!! He rejected a move, because he thoughtthatafter 20.exf4 Kxg7 21.f5 White has sufficient compensation for the exchange. But since he felt that he should be better, he decided to maintain the tension. By the way, once again it's not good for White to win an exchange back:(21.Bd5 Rae8 22.Bxe4 Nxe4 and we are in the same type of position: good knight vs bad bishop.) ] 19.e5! dxe5 20.e4! With a pawn sacrifice White achieves his goal of bringing his dark squared bishop into the game. From now on Black does not have a satisfactory defence against the attack. 20...exd4 21.Nxg7! [I also considered 21.cxd4 but felt it was too slow. Post mortem confirmed that: 21...Nh4 22.Nxh4 Qxd4+ 23.Be3 Qxe4 24.Qxe4 Rxe4 25.Nf5 and Black is probably better.] 21...Ne5 [21...Nh4 22.Qg3 Nxe4 23.Qg4 is winning for White.] 22.Qh3 [22.Qg3?? would be a horrible mistake in view of 22...Nxe4-+] 22...dxc3!? A very interesting resource in a difficult position, which almost works. [22...Nxe4 is losing: 23.Nxe8 Qxe8 24.Bh6 Nxc3 25.Bb3 Kh8 26.Qf5 with the idea of Qf6 26...Nd7 27.Bc2] 23.Bxc3! [23.Nxe8 cxd2 24.Nxf6+ Qxf6 25.Rxf6 d1Q+ 26.Rf1 Qd4+ 27.Kh1 and Black is better due to an extra pawn and centralized knight.] 23...Kxg7 24.Qg3+ [It was not too late to go wrong with 24.Bxe5?? Rxe5 25.Qg3+ Ng4!] 24...Ng6 25.Bxf6+ [25.Qg5 looked very tempting, but unfortunately there is no clear win after that, for instance 25...h6 26.Bxf6+ Kh7 27.Qh5 Qd6! 28.Bxf7 Qc5+ 29.Qxc5 bxc5 30.Bxe8 Rxe8 with approximately equal position] 25...Qxf6 26.Rxf6 Kxf6 27.h4! Only this move secures a winning position for White [27.Qf3+ Kg7 28.Qxf7+ Kh6 would lead to unclear position.] 27...Re5 [27...Rad8 28.Qg5+ (28.h5 doesn't work in view of 28...Ne5 29.Qf4+ Kg7 30.Qg5+ Kh8 31.h6?? Nf3+-+; however, 28.Qf3+ Kg7 29.Qxf7+ Kh6 30.Bd5 is also good.) 28...Kg7 29.h5 Rd1+ 30.Kh2 Re5 31.Qg4 and Black can't save the knight.] 28.Qf3+ Kg7 29.h5 White wins a knight now and Black tries his last resourse hoping to build up a fortress. 29...f6!? 30.hxg6 hxg6 31.Qd3 Rae8 32.Qc4 R5e7 33.Qc6 Rxe4 34.Qxc7+ R8e7 [I was expecting 34...R4e7 but white still wins after 35.Qd6 with the idea Bc4, Bd3, Qg3 . Black will have to play g6−g5 and then White 50 puts his queen and bishop on b1-h7 diagonal.] 35.Qb8 Kh6 36.Qf8+ Kg5 37.Bf7 Rc7 [Right after the game Alex mentioned a possibility to sacrifice rook for the bishop in order to create a fortress. However, it doesn't seem work, e.g. 37...Re3 38.Qg7 (38.a4 R3e4 39.Bd5 Re1+ 40.Kh2 is also possible) 38...Rxf7 39.Qxf7 Rxa3 40.Qd5+ Kh6 (40...f5 41.Qd8+ Kg4 42.Qd1+ Kh4 43.Qd6 Ra1+ 44.Kh2 Kh5 45.g4+ Kg5 46.Qd8+ winning a rook on the next move.) 41.Qd6 Ra1+ 42.Kf2 (42.Kh2 Rf1) 42...Ra5 43.g4 f5 (43...Kg5 44.Kg3) 44.Qd2+ Kg7 45.g5 and white wins.] 38.Qg7 Rc1+ 39.Kf2 Rc2+ 40.Kf3 Rf4+ 41.Ke3 1-0 (23) Goldin,A − Yermolinsky,A [E33] 11th Chicago Open Oak Brook, IL (7), 05.2002 [Albert Chow] 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 Nc6 5.Nf3 d6 6.Bd2 0-0 7.a3 Bxc3 8.Bxc3 Qe7 9.b4 e5! 10.d5 Nb8 11.e4 Nh5! 12.g3 f5! 13.Be2 fxe4 14.Qxe4 Bf5 Counterplay! 15.Qe3 Nf6 16.Nh4 Bh3 17.Rg1 Ng4! 18.Bxg4 Bxg4 A dubious gambit in place of the solid 19.h3? [19.f3] 19...Bxh3 20.Rh1 Bf5 21.Nxf5 Rxf5 22.Qe4 g6 23.f4 Nd7 24.0-0-0 Qf7 25.Rde1 Rf8 26.fxe5 Nxe5 27.Re2 a6 28.Rhe1 b5 29.c5 Nc4 30.Qd4 Re5 31.Rxe5 dxe5 32.Qe4 Qf2 33.d6 Qxg3 34.Qd5+ Kg7 35.Bxe5+ Nxe5 36.Qxe5+ Qxe5 37.Rxe5 cxd6 38.cxd6 Rd8 39.Re7+ Kf6 40.Rxh7 Rxd6 41.Rh1 g5 white resigns. 0-1 (24) Onischuk,A (2740) − Chow,A (2280) [E59] Chicago open (1), 24.05.2002 Illinois Chess Bulletin
