=French Defence: Advance Variation= Here Black has built up quite some pressure on White's d4-pawn, luckily there are still enough defenders. White has several options. They can:
 * 1) Prepare a gambit by playing 6.Bd3.
 * 2) Develop their pieces, but without the intention of sacrificing a pawn (6.Be2)
 * 3) Prepare an expansion on the queenside (6.a3).
