Caro-Kann Tal 11.Nxe6 Andreu

The main line Caro-Kann Defence typically continues 4.Nxe4 Bf5 5.Ng3 Bg6 6.h4 h6. Usually White plays h4-h5 on move 7 or 8. The resulting pawn structure limits Black’s endgame possibilities. The problem is h5 can also be difficult for White to defend. Half a center ago Bobby Fischer tried 6.h4 without pushing to h5 in his US Championship game vs Steinmeyer.

If White plays 6.h4 h6 7.Nh3 (or 7.Ne2), then he gains time with 8.Nf4 due to the threat of 9.Nxg6. Black would not want to play 9…fxg6 so he retreats with 8…Bh7. Mikhail Tal developed a sacrificial idea of Nf4, Bc4 and Nxe6.

Javier Andreu followed Tal - Botvinnik in our APCT postal game. I found an innovation over Botvinnik with 12…Bxg3. I may have found this idea in a book somewhere. Black captured the bishop with 17…Nxe4. If White recaptures, Black has a perpetual check.
