The following is the French defence, advance variation:
[FEN ""] 1. e4 e6 2. d4 d5 3. e5 *
My question is how Black should play his King's Bishop. Any time that Bishop moves the White Queen can go to g4 and force Black to disrupt his King-side castling pawns, e.g. as in the following typical continuation:
[FEN ""] 1. e4 e6 2. d4 d5 3. e5 Bb4+ 4. Bd2 Nc6 5. Qg4 g6 *
Should Black King's Bishop be fianchetoed instead? I think not cause targeting the spearhead of the White's pawn chain doesn't not look very promising, esp. from a fiancheto position where advancing a pawn to f6 lacks g-file pawn support. So, how should Black employ his King's Bishop?
