Keres Attack with 6...e5

So far at least two readers have advocated studying 6...e5 for Black in the Keres Attack against the Scheveningen Sicilian. My opening book of master games since 2001 (MT IV) indicates that this move is the least popular (44 games of 629) of the four principal continuations. Even so, Linuxguy_on_FICS claims it is the most principled reply, so it's worth a look.


After 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e6 6.g4 e5 we have the starting position.



Two moves appear in the Encyclopedia of Chess Openings:

7.Nf5
7.Bb5

My opening book MT IV indicates that Bb5 is twice as popular as Nf5, but that Nf5 scores much better. The main line in ECO from Nf5 ends with a substantial edge for White. 7.Bb5 breaks into three lines in ECO--two end as unclear, one ends with a substantial advantage for White.

7.Nf5

ECO gives only 7...h5 in reply to 7.Nf5, but two other moves played in high level games in 2008 complicate my preparations to play the White side.

7...g6 was played against Bobby Fischer in 1964 in a simul, and Fischer lost. It was played a few more times until Sequera Paolini-Alvarez, San Felipe 2008, which Black won.

7...Nc6, a standard Sicilian move, appears to have been introduced into practice in the Bundesliga: Gharamian-Nisipeanu, Trier 2008. That game ended in a short draw. However, a reasonable appearing novelty in a more recent game went badly for White. Perhaps these games deserve closer attention before moving on to 7.Bb5.

  1. Just looking at the diagram, Bb5 looks incredibly strong compared to playing Nf5 (yet).

  2. I would also prefer 7.Bb5, but I have usually no chance to play Keres Attack in my games :(
