You mentioned that this allows 11.b4, holding the pawn, but 11...b6 seems like a good response. I don't see any way for White to hold on to that pawn. In fact, I think 11.b4 is a weak move which weakens White's queenside pawn structure, and gives Black's g7 bishop more scope. Oh, my program likes 10...Qc8. --Peter
