6...b5?
6...b5?, apparently a natural move to expand on the queenside as prepared by ...a6, is a mistake on account of 7. Nd5!.
7. Nd5! appears to give up White's e-pawn. However, 7...Nxe5?? falls into a common amateur trap. After 8. Nxb5! (threatening Nc6+) axb5 9. Bb6 Black's queen is trapped. If 9...Qd7 10. Bxb5 Qxb5 11. Nc7+ forks the queen.
