Opening traps · As White

Sea-Cadet Mate

After 8...Bxd1, White has mate in two. The queen capture is the stated mistake; the opening does not force Black to choose it.

Ideas behind the moves

Bxf7+
Give Bxf7+ with the bishop. This drives the king to e7 in the prepared mating continuation.
Nd5#
Play Nd5#. The knight gives check and the bishop and knight cover the king’s escape squares.
