Queen's Gambit Accepted, Classical Defense

SMBAT GARIGINOVICH LPUTIAN vs. MAXIM DLUGY
New York, 1998

1. d4, d5
2. c4, dxc4
3. e3, e6
4. Bxc4, Nf6
5. Nf3, c5
6. Qe2 ....

If 6. dxc5 Qxd1, the exchange of Queens would be bad for White.

6. .... a6
7. dxc5, Bxc5
8. e4, Qc7
9. e5, Ng4
10. 0-0, Nxf2
11. b4, Nh3+
12. Kh1, Nf2+
13. Rxf2, Bxf2
14. Nbd2, Ba7
15. Ne4, 0-0
16. Nf6+ ....

The sacrifice intends to open-up the g-file.

16. .... gxf6
17. gxf6, Nd7
18. Qd2 ....

The Queen is bound for g5, threatening mate.

18. .... Rd8
19. Qg5+, Kf8
20. Bf4, Qc6

If 20.....Qxc4, then 21. Bd6+ Ke8, 22. Qg8+ Nf8, 23. Qxf8+ Kd7, 24. Qe7+ Kc6, 25. Qxd8 ... and White wins more materials.

21. Rd1 ....


The threat of Bd6+ has become more plausible.

21. .... Nxf6
22. Rxd8+, Ne8
23. Ne5, Resigns

The White Queen has nowhere to go.  If 23....Qb6, then White continues the attack by 24. Rxe8+ Kxe8, 25. Qg8+ Ke7, 26. Qxf7+ Kd6, 27. Nd7+ and Black loses his Queen.

If 23....Qc7, then 24. Ng6+ hxg6, 25. Bxc7 ....

If 23....Qa4 or Qe4, then 24. Nd7+ Bxd7, 25. Bd6 mate.

ALEXANDER ALEKHINE vs. EERO EINAR BOOK
Margate, 1938

1. d4, d5
2. c4, dxc4
3. Nf3, Nf6
4. e3, e6
5. Bxc4, c5
6. 0-0, Nc6
7. Qe2, a6
8. Nc3, b5
9. Bb3, b4
10. d5, Na5
11. Ba4+, Bd7
12. dxe6, fxe6

Correct reply. If 12....Bxa4, then 13. exf7+ Ke7, 14. Nxa4 which favors White.

13. Rd1, bxc3
14. Rxd7!! ....

A crushing and unexpected attack.

14. .... Nxd7
15. Ne5!, Ra7
16. bxc3, Ke7

Black removes his King from the pin.

17. e4, Nf6

If 17....Nxe5, then 18. Bg5+ wins the Black Queen.

18. Bg5, Qc7
19. Bf4, Qb6
20. Rd1, g6
21. Bg5, Bg7
22. Nd7!! ....

Giving room for an attack move: e5 which would have a disastrous effect.

22. .... Rxd7

Black has no choice but to take the pesky Knight.

23. Rxd7+, Kf8
24. Bxf6, Bxf6
25. e5!!, Resigns

Black would have no reply to White's 26. Qf3+ with a mating threat at f7.
