Légal's Mate
Thirteen moves, from 1750. The trap that punishes trusting a pin too much.
This game is nearly three hundred years old and it still catches people every day. It teaches two things at once: how to use that f7 line of sight you saw in the Italian, and why a pin is NOT a chain — sometimes the pinned piece can move, and the price is worth paying. Thirteen moves; take your time.
Légal against Saint Brie, Paris, around 1750.
