Beat Légal's Mate
Black to move. Don't take it.
Snort just left his queen hanging. It's bait.
Hint
Taking the queen gets you mated. Remove the attacker instead.
Answer
dxe5 — Correct! No knight, no mate. You're a pawn down, but your king is safe.
The tempting mistake
Taking the queen is the trap: Bxf7+, Ke7, Nd5 and it's mate.
The idea
When a queen is free, ask why. Kill the attacker first.
