TBOC_7 (Breslau Variation)

Post by Alibaba »

Hi,

i started a new tournament called "TBOC_7" to find out more about the famous "Breslauer Variante" in the open spanish opening.

Once long time ago the move 10. Re1 seems to be a strong move, but in 1913 Mr. Bergman and Tarrasch found the interesting continuation...
which leads to the following position:

[d]r2q1rk1/2p2ppp/p2b4/1p1pn3/3NP1b1/1BP5/PP4PP/RNBQR1K1 w - - 0 14

so black sacrifies a bishop for a pawn, to make use of it's faster development to get a strong attack on the white king...

All Engines play, starting with this position, at Time control 40m in 180min, followed bei 40m in 120 min, rest in 5min + 30 s
but this time without ponder, so most engines but komodo can use 4 Cores....

What do you think, is this position playable or even good for black?

Here is a game which was won be Deep Fritz 13, Fritz found a very good move, (16. Re1) which stops the black attacking possibilies and leads to a better endgame for white.....

This is not commonly played nowadays. The first piece sac (12. .. Bd6) might be ok, but the line with the Bishop sac 15. .. Bxh3 is bad for Black. A fairly recent example:

[Event "Russian Team Championship"]
[Site "Sochi RUS"]
[Date "2007.05.05"]
[Round "4"]
[White "Pavel Smirnov"]
[Black "Sergey Vokarev"]
[Result "1-0"]
[ECO "C83"]
[EventDate "2007.05.02"]
[WhiteElo "2631"]
[BlackElo "2475"]
[PlyCount "47"]

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Nxe4 6. d4 b5
7. Bb3 d5 8. dxe5 Be6 9. c3 Be7 10. Re1 O-O 11. Nd4 Nxe5
12. f3 Bd6 13. fxe4 Bg4 14. Qd2 Qh4 15. h3 Bxh3 16. gxh3 Nd3
17. Rf1 dxe4 18. Qg5 Qxh3 19. Qg2 Qh5 20. Be3 Ne5 21. Nd2 Ng4
22. Bf4 e3 23. Bxd6 exd2 24. Bxf7+ 1-0

Fritz is not exactly orginal with that 16th move. Actually, the game follows Botvinnik-Kan, 1952, through white's 21st move.
