But no time for that until maybe >tonight. More thought. I had not given this much OTB study, but it stayed in the back of my mind. What about this: Be4 h5 Bf3 e5! It would seem that Bf3 is no good, since the point of Be4 was to restrain the black e-pawn so that black can't penetrate on the kingside while white swings the king to the queenside. So maybe either the original premise that Be4 is required immediately is flawed, or else Bf3 is not playable here since the same situation arises here?
