Any chess experts out there?
I need something, preferably mid-game, which a) has a name (e.g "Ruy Lopez" or "Berlin Wall") and b) involves laying a trap. Ideally, it would be the type of trap where every "correct" move just digs the hole deeper.
Edit: I know how to play chess - learned over 30 years ago. I'm just not good enough to have studied the kind of thing I'm looking for.
