Chess Terms

Term of the day

Chess Fork

One move, two threats: a fork attacks two pieces at once, and only one can be saved.

More terms

A pinned piece cannot move without exposing a more valuable one behind it.

The reverse of a pin: the valuable piece is hit first and the one behind it falls.

Discovered Attack

A piece steps aside and uncovers an attack from the piece it was blocking.

Back Rank Checkmate

Mate on the last rank: the king's own pawns leave it nowhere to run.
