Cohn admitted after the game that he blundered away a Pawn on move 10, which forced him to attack most vigourously to compensate for the material deficit. His attack was so intense it won him not only the game but a brilliancy prize in a tournament filled with beautiful games! |

Both players hasten to complete their development. |

Since White is compelled to lose a Pawn, he seeks compensation with a strong Pawn center and a K-side attack. |

Forcing the Knight away from the K-side. |

|
Opening more lines for attack. Black's isolated QP and lagging development are crimping his game. |
|
| |
|
|
19... Qa5 20. g5 Nd7 21. Nd5
|
Seizing this powerful outpost at once. Depending on your taste in metaphors, this Knight is a rusty nail in Tchigorin's knee or a bone in his throat. |
|
| |
|
|
21... Qd8 22. h4 Nb6 23. f5
|
Forcing Tchigorin to remove the Knight, but this opens the diagonal of Cohn's QB, which aims ominously at Tchigorin's King. |
|
| |
|
|
23... Nxd5 24. Rxd5 Bd7 25. e5
|
A very powerful move. If Tchigorin now plays 25... PxP?? Cohn has 26 P-B6!! P-KN3 27 B-KR3!! and Tchigorin can resign. |
|
| |
|
|
25... Bc6 26. e6
|
26... BxR? now falls to 27 BxB PxP 28 PxP Q-K2 29 Q-Q4!!! and Tchigorin has no defense against 30 R-B7. |
|
| |
|
|
26... fxe6 27. fxe6
|
Now 27... BxR? fails to 28 Q-B7 ch K-R1 29 BxB R-K2 30 Q-B5 K-N1 31 B-K4!! and Black is defenseless. |
|
| |
|
|
27... Qe7 28. Qf7+ Kh8 29. Rdf5
|
White's powerful battery on the KB file threatens to break into Black's position decisively. |
|
| |
|
|
29... Qxf7 30. exf7 Re2 31. Rf1f2
|
Now Cohn has a promotion threat as well as mating threats. |
|
| |
|
|
31... Rxf2 32. Rxf2 d5 33. Bd4

Preventing Black from gaining counterplay with ...B-B4. |

33... h5 34. g6 Bd7 35. Re2
|
THreatening 36 R-K5 followed by 37 RxP mate. |
|
| |
|
|
35... Bd6 36. Bh3 Bb5 37. Re6

Tchigorin resigns. If 37... B-B2, Cohn has 38 B-QB5! B-N3 39 BxB PxB 40 R-K5 forcing mate. |
