=Alekhine Defence= With this move, White defends the d4-pawn with the bishop while not allowing the ...Bg4 pin. Black now almost always plays 7...Bf5, since that is the only logical square for the bishop. Then White plays 8.Nc3 and then Black plays 8...e6, and now White plays 9.Nf3 when Black has a choice between several moves.
