لاسكر أمام تاراش
Lasker vs. Tarrasch, 1914
In this 1914 game between بطولة العالم للشطرنج إيمانويل لاسكر and زيغبرت تاراش, Black exchanged down into this position because he thought it was a win, but White used the maneuver above to draw the game.
- 40. h4 Kg4
- 41. Kg6! Threatening 42. h5 (Giddins 2007:8). Black had only considered the line: 41. Kf6? c4 42. bxc4 bxc4 43. Ke5 c3 44. bxc3 a4 45. Kd4 a3, winning (Kasparov 2003:209).
- 41... Kxh4 This move is مسرد الشطرنج and the white king gains a tempo to return on a different diagonal which is not obstructed by his pawns (Giddins 2007:8).
- 42. Kf5 Kg3
- 43. Ke4 Kf2
- 44. Kd5 Ke3
- 45. Kxc5 Kd3
- 46. Kxb5 Kc2
- 47. Kxa5 Kxb3 ½-½
The theme of this endgame was used later by Réti in the study (Kasparov 2003:210).
