Lasker's Trap (Albin Counter Gambit)

This is one of the most popular tricks and runs as follows:

1. d4, d5
2. c4, e5
3. dxe5,d4
4. e3? ....

White should play 4. Nf3 in order to put pressure on the Queen's pawn.

4. .... Bb4+
5. Bd2, dxe3!

6. Bxb4? ....

White might fare better if 6. Qa4+ Nc6, 7. fxe3 Qh4+, 8. Kd1 (not 8. g3 because of 8....Qe4) Qf2, etc.

6..... exf2+
7. Ke2, exg1=N+
8. Rxg1, Bg4+

and Black captures the Queen on d1.
