[Event "New York"] [Site "?"] [Round "0"] [White "Capablanca"] [Black "Black"] [Result "1-0"] [ECO "C42"] [Opening "Russian Game: Classical"] 1. e4 e5 2. Nf3 Nf6 3. Nxe5 d6 4. Nf3 Nxe4 5. d4 d5 6. Bd3 Bd6 7. c4 { White begins to undermine the defense of the e4 knight.} 7... Bb4+ {Black force s White to interpose on d2 so he can trade off the exposed knight, but loses a tempo by moving his bishop a second time. Note also that the bishop is en prise on b4.} 8. Nbd2 O-O 9. O-O Re8 { White, having unpinned his d2 knight, was threatening to capture on e4.} 10. cxd5 Nf6 { Black wants to post his knight on d5, where it can't be chased by a White pawn. } 11. Ne5 {White takes advantage of Black's loss of time to bring his own knight to an agressive square, attacking Black's weakness on f7.} 11... Nbd7 { This is a mistake, cutting his bishop off from the kingside.} 12. Ndf3 { Not only supporting his knight but threatening to go to g5.} 12... Nxd5 { This is a blunder: with one White knight already aimed at f7 and the other ready to jump in at e5 or g5 Black should not open the diagonal leading to that square.} 13. Nxf7 {Breaking through before Black has a chance to defend the diagonal by ...N7f6 and ...c6 or ...Be6.} 13... Kxf7 14. Ng5+ Kf8 15. Qh5 { White has too many threats. Black can't cover the mate on f7 without losing too much material, since the queen is indirectly attacking the knight on d5, e. g. so Black resigned here.} 15... Qe7 16. Nxh7+ Kg8 17. Qxd5+ Kh8 18. Qh5 { Black is two pawns down and still getting checkmated.} 1-0
