Sicilian Defense, Richter-Rauzer Attack

PAUL KERES vs. LASZIO SZABO
Budapest, 1955

1. e4, c5
2. Nf3, Nc6
3. d4, cxd4
4. Nxd4, Nf6
5. Nc3, d6
6. Bg5 ....

This reply of White is known as the Richter-Rauzer Attack (invented by Kurt Richter), threatening to double Black's pawns after Bxf6 and forestalling the Dragon by rendering 6....g6 unplayable.

6. .... e6
7. Qd2 ....

Prepares for castling on the queen-side.

7. .... Be7
8. 0-0-0, 0-0
9. f4, a6
10. e5, dxe5
11. Nxc6, bxc6
12. fxe5, Nd7

If 12....Nd5, then 13. Bxe7 Qxe7, 14. Ne4... then 15. Nd6 with a good position for White.

13. h4, Rb8
14. Qe3, Re8
15. Rh3!, Qa5
16. Bxe7, Rxe7
17. Rg3, Re8
18. Rxd7, Bxd7
19. Bd3, h6
20. Qf4 ....

If 20. Qxh6, then 20.....Qxf4.  Clearly, White has a better plan.

20. .... Kf8
21. Rxg7, Kxg7
22. Qf6+!!, Kf8

If 22….Kg8 then 23. Qxh6 f5, 24. exf6 and mate next move.

23. Bg6, Resigns

Black cannot defend his f7 pawn without losing.  If  23....Re7, then 24. Qh8 mate.  A superb ending.
