The Lasker Trap
The pawn on f2 captures with check and under-promotes to a knight with check.
Opening: Albin Countergambit. Set by Black. Level: Intermediate.
Practise setting and escaping itThe moves
1.d4 d5 2.c4 e5 3.dxe5 d4 4.e3 Bb4+ 5.Bd2 dxe3 6.Bxb4 exf2+ 7.Ke2 fxg1=N+
It only works after a mistake
White must play Bxb4 for it to work. The Albin Countergambit is risky but playable; the trap needs White to take the bishop.
How to avoid it
fxe3 instead of taking the bishop.
