I played a game today in the Sicilian Defence. I was White. I was surprised to see the move 5. ... e5 ! Is this playable in the Sicilian?
[FEN ""]
[StartPly "5"]
[Title "Is 5. ... e5 playable?"]
1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5
My intuition tells me that this move weakens the d6 square so much and White can develop an attact quite easily. The continuation
[FEN ""]
[StartPly "5"]
[Title "Is 5. ... e5 playable?"]
1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 6. Ndb5
is obvious. White seizes control of the b5 square aiming for the weak d6 square.
I believe that Black should answer 5. ... e6 taking away the important d5 square from White. Has anyone seen the ... e5 variation before?
