Watch out for the trap of the deadly Legal’s Mate! It comes out of the Philidor defense, 1. e4 e5 2. Nf3 d6 (Philidor’s) 3. Nc3 a6? 4. Bc4 Bg4 5. Nxe5! Bxd1? 6. Bxf7+ Ke7 7. Nd5# and it’s curtains! Don’t just memorize the moves though, understand the concept (good advice for any series of moves) of being able to check such that the king is trapped and can only move to e7, and that nothing can capture the Knight when it lands on d5. If the bishop, for example moves off its original square, then the f8 square comes available for the king to escape to and woops! You lost your queen for nothing.
