Caro-Kann Defense Exchange Variation

MIKHAIL TAL vs. LEONOV
Riga 1949

1. e4, c6
2. d4, d5
3. exd5, cxd5

The Exchange Variation of the Caro-Kann.

4. Bd3, Nf6
5. h3, h6
6. Bf4, e6
7. Nf3, Bd6

The Bishop at f4 is at an advantageous position.  It would be prudent to neutralize the Bishop at once.

8. Bxd6, Qxd6
9. c3, Nc6
10. 0-0, 0-0
11. Qe2, Re8
12. Ne5, Qc7
13. f4, Nxe5
14. fxe5, Nh7
15. Qh5, Re7
16. Na3, a6
17. Nc2, Qd7?

Why block the Bishop's way?  If the Queen intends to travel to f8, Black could have moved 17....Qd8 at once

18. Ne3, Qe8
19. Rf6, Qf8

If 19....gxf6, then 20. Bxh7+ Kxh7, 21. exf6 Rc7, 22. Rf1 ... and White gets attacking position in exchange.

20. Rf4, Bd7
21. Ng4, Be8
22. Nf6+ ....

22. ....  Nxf6

If 22....exf6, then 23. Bxh7+ Kxh7, 24. exf6 Rc7, 25. Rg4 ... and White weaves a mating net.

23. exf6, Rc7

If 23....gxf6, then White mates with 24. Rg4+ Kh8, 25. Qh4 and 26. Qxf6.

24. fxg7, Kxg7

Of course not 24....Qxg7 then 25. Rg4.

25. Qe5+, Resigns

White would have tremendous material advantage after 25....f6, 26. Qxc7.
