The Noah's Ark Trap
The bishop on b3 gets trapped by a chain of pawns, like the ark.
Opening: Ruy Lopez. Set by Black. Level: Intermediate.
Practise setting and escaping itThe moves
1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 d6 5.d4 b5 6.Bb3 Nxd4 7.Nxd4 exd4 8.Qxd4 c5 9.Qd5 Be6 10.Qc6+ Bd7 11.Qd5 c4
It only works after a mistake
White must play Qxd4 for it to work. Black's moves are all normal; White falls into it only by grabbing on d4 with the queen.
How to avoid it
Bd5 or c3 instead of taking with the queen.
