Nc3 g6 3. e4 d6 4. d4 Bg7 5. Be2 Na6 { A rare line of the King's Indian Defense. Black's queenside knight comes to the c5-square faster, but is also more vulnerable without ... a7-a5 as its anchor, preventing b2-b4. } 6. Nf3 O-O 7. Be3 e5 8. d5 Ng4 9. Bg5 f6 10. Bh4 g5 { This same-side pawn avalanche looks risky, but the center is sufficiently locked. Black has to play carefully, though. } 11. Bg3 Nh6 { Taking the knight to safety and preparing ,,, f6-f5. } 12. Nd2 f5 13. exf5 Nxf5 14. O-O Nd4 15. a3 Bf5 16. Nde4 Nxe2+?! { Even though bishops are "usually" better than knights, in this specific position the d4-knight was better-placed, as it was almost impossible to chase away or trade off. } (16...

Qxe2 g4? { Strangely, White can use this g4-pawn as a hook (usually hooks aren't this far advanced...). } (17... Qe8 { , once again preparing ... Na6-c5, was better. } 18. Nxg5 Nc5 19. Nge4 b6 $16) 18. f3 { The files are opening too quickly for Black to defend; also, the knight is still on a6. Krush goes on to play a very nice attacking game. } 18... h5 19. b4 h4 20. Be1 gxf3 21.
