Is 9.e5 working?
Scheviningen 6.Be2 a6/b5
Sort:
You should play 7. Qc7 first and then b5. In your position your best response to 8.Bf3 is e5 blocking the diagonal, in the variation you posted after 9. e5 black is positionally lost.
In this postion is it possible to simply play a6, b5 and attack the e-pawn? In many games they develop the kingside first but it seems like White can't do much about the king now.
