After this move White's game is lost. White cannot play Kt × Kt P, because Kt × Kt will win a piece. Therefore he must play B - Kt 3, either before or after Kt × Kt, with disastrous results in either case, as will be seen.
| 11. Kt × Kt ch | Q × Kt | |
| 12. B - Kt 3 | B - Kt 5 | |
| 13. P - K R 3 | B × Kt | |
| 14. Q × B | Q × Q | |
| 15. P × Q | P - K B 3 |
A simple examination will show that White is minus a Bishop for all practical purposes. He can only free it by sacrificing one Pawn, and possibly not even then. At least it would lose time besides the Pawn. Black now devotes all his energy to the Queen's side, and, having practically a Bishop more, the result cannot be in doubt. The rest of the game is given, so that the student may see how simple it is to win such a game.

There is no necessity to pay any attention to the King's side, because White gains nothing by exchanging Pawns and opening the King's Rook file.
| 20. P × P | R P × P | |
| 21. P - Kt 3 | P - B 3 | |

If White takes the proffered Pawn, Black regains it immediately by R - Kt 5, after P × B P.
