Bf4 { White tries to take advantage of Black's pinned knight.} 10... Nfd7 11. Bg2 Rd8 {The Black rook prepares to take over the d-file from White's queen.} 12. Qc1 f6 13. O-O Be6 { This move relieves some of the pressure White has on Black's pinned knight.} 14. Nxe5 Nxe5 15. a5 a6 16. Ne4 Bb4 17. Nc5 Bc8 18. Ra4 {Although White sacrifices the a-pawn he doesn't receive enough play for it. 18.Bxe5 fxe5 19. f4 Trying to take advantage of Black's king being in the center is a better plan.} 18... Bxa5 19. Nd3 O-O 20. Be4 {20.Bxe5 fxe5 21.Qc5 Perhaps this is what White originally intended only seeing too late that 21...Bb6 22.Qxe5 Qxe5 23.Nxe5 Rxf2 24.Rxf2 Rd1+ 25.Bf1 Bh3 when White can't stop Rxf1 mate.} 20... Bb6 21. Qc2 g5 {An exception to the rule that one shouldn't move the pawns in front of the king which usually leaves the monarch vulnerable to attack. Black's idea is to ease the pressure on his pinned knight.} 22. Bxh7+ { 22.Bxe5 fxe5 23.Nxe5 Qxe5 24.Qb3+ Kh8 25.Qxb6 Rd2 would give Black good chances due to his control of White's second rank.} 22... Qxh7 23. Bxe5 Ba7 { This was the point of Black's defense. He now gains a tempo on White's dark-squared bishop which he uses to develop a powerful counterattack.} 24. Bc3 b5 25. Raa1 c5 { Black's queenside pawns push the White pieces to less active positions.} 26. Qc1 c4 27. Ne1 Bb7 28. Nf3 {28.Ng2 would allow Black a mating attack.} 28... g4 29. Ng5 Qh5 { White resigned. 29...Qh5 White resigned as mate was coming after...} 30. Ne6 Qd5 {when White has no good way of stopping Qg2+ mate.} 0-1
