Nf3 e6 6. cxd4 b6 7. Nc3 Nxc3 8. bxc3 Qc7 9. Bd2 d6 10. Bd3 Nd7 {A careless move, 10/\Bb7 is better (SL)} 11. Ng5 {(Threatening 12 Qf3 with a double attack on f7 and a8. Fritz prefers 11 O-O which it assesses as +0.38 after ...Bb7 12 Bf4 Be7 13 exd6 Bxd6 14 Bxd6 Qxd6 15 Rc1. But I was hoping to gain a tempo by omitting O-O.) (PW) ....... I was taking a long time around here to try and work out the best plan for B in a difficult position. The best I could see was an exchange sacrifice with play on W's weakened white squares (SL)} Bb7 12. Qh5 g6 13. Qh3 dxe5 14. Bxg6 hxg6 {Black correctly gives up the exchange to gain counter-play. 14...fxg6?? would have lost quickly after 15 Qxe6+ when Black has the choice of losing his queen after ...Be7 16 Qf7+ Kd8 17 Ne6+, or getting mated after ...Kd8 16 Nf7+ Kc8 17 Qe8+) (PW)} 15. Qxh8 O-O-O {But this is a serious mistake. Correct is 15...Qc4! preventing White from castling K-side and threatening ...Ba6 followed by ...Qe2mate. Fritz gives 16 Qh3 exd4 17 cxd4 Qxd4 18 O-O Qxd2 19 Nxe6 fxe6 20 Qxe6+ Be7 21 Rad1 Nf8 22 Qxe7+ Kxe7 23 Rxd2 as -0.5.) (PW) ..... .. 15/\Qc4 may be better but then W can defend the weak white squares by Qh3 and Qe3/f3 for example. The position after 15/\Qc4 16 Qh3 Ba6 17 Qe3/ Qf3 exd4 may be playable for B (SL)} (15... Qc4 16. Qh3 Bg7) (15... Bxg2 16. Rg1 Bd5 17. Rg3) 16. Nxf7 Ba6 {again if 16/\Qc4 17. Qh3 with same idea (SL)} 17. c4 {Exploiting the fact that Black/^s king is now on the c-file - Black should again have preferred ...Qc4 on his last move. (PW)} Bxc4 {Necessary as . ..Qxc4 now loses the queen after 18 Rc1 (PW)} 18. Nxd8 Qxd8 19. Rc1 b5 20. Qh3 {Eyeing the possibility of Qxe6, but 20 a4 a6 21 axb5 axb5 first may have been more accurate (PW)} Kb8 {W is now clearly winning and time trouble was affecting the play for B (SL)} 21. Rxc4 {Returning one exchange to take control of the b-file and the h1-a8 diagonal for the attack (PW) ....... W rightly decides that the black QB is too strong to leave on the board, and getting rid of it simplifies his task (SL)} bxc4 22. Qxe6 Qc7 23. dxe5 {If White had played 20 a4 first, then Black would no longer have the resource 23 O-O exd4 24 Rb1+ Nb6 which he can play here. But now the endgame an exchange and a pawn down after 23...Qxe5+ is hopeless for Black, and 23...c3 can be met by 24 Qb3+ (PW)} Bc5 24. O-O {13 moves after Fritz recommended. Not 24 Qxc4?? Bxf2+ (PW) ...... At last! The white KR enters the game and it is all over for B (SL)} Nxe5 25. Rb1+ Bb6 26. Qg8+ Kb7 27. Qd5+ Kc8 28. Bf4 Bxf2+ 29. Kf1 {#r} 1-0
