King's Gambit: the Cunningham Bishop

4...Bh4+ looks like a free hit, it drives your king to f1. But the bishop now stands on h4 attacked by the knight on f3, and 5...Nf6?? loses it to 6.Nxh4. The most-played mistake anyone makes against this opening.

A position this opening is aiming for.

Traps are only worth knowing if somebody actually falls into them, so each one here was checked against what club players really play, not only against what an engine would.
