[Event "Moscow"] [Site "?"] [Round "0"] [White "Grigoriyev"] [Black "Alekhine"] [Result "0-1"] [ECO "C12"] [Opening "French: MacCutcheon"] 1. e4 e6 2. d4 d5 3. Nc3 Nf6 4. Bg5 Bb4 {The very sharp McCutcheon Variation.} 5. e5 h6 6. exf6 {Nowadays the bishop usually retreats to d2 or e3 instead.} 6... hxg5 7. fxg7 Rg8 8. h4 { White moves quickly to open up more lines on the kingside.} 8... gxh4 9. Qg4 Be7 {But there is going to be great difficulty defending the weak pawn at g7.} 10. g3 c5 {This is a critical position, and White makes a mistake. The correct move is to remain consistent with the opening plan, and keep playing on the kingside. Now Alekhine seizes the initiative and never lets go.} 11. O-O-O Nc6 12. dxc5 Qa5 { See how quickly the picture has changed. Black is now on the attack.} 13. Kb1 e5 14. Qh5 Be6 {The pawn at g7 has become irrelevant. Black doesn't care about the pawn at d5 either. The initiative is much more important.} 15. Nxd5 Bxd5 16. Rxd5 Nb4 17. Rxe5 { Both sides attack. But the one with the initiative always has the advantage.} 17... Qxa2+ 18. Kc1 O-O-O {The move performs double-duty. The king flees to safety and the rook at d8 now cuts off the escape path of White's monarch.} 19. Bd3 Qa1+ 20. Kd2 Qxb2 21. Ke3 {21.Rxe7 Qxc2+ 22.Ke1 Nxd3+ 23.Kf1 Qxf2+} 21... Bf6 22. Qf5+ Kb8 23. Re4 Rxd3+ 24. cxd3 Bd4+ 25. Kf4 { 25.Rxd4 Nc2+ 26.Ke4 Re8+ 27.Kf4 Qxd4+ 28.Kf3 Ne1+} 25... Qxf2+ 0-1
