Discovered Check

Key Concept

Moving a piece reveals check from the piece behind it

How This Tactic Works

A discovered check is a discovered attack where the revealed piece gives check to the enemy king. Since the opponent must address the check, the moved piece — which may be delivering its own threat simultaneously — is free to capture material or create additional threats. A double check (discovered check where both the moved piece and the revealed piece check the king simultaneously) is even more powerful: the king must physically move since it's impossible to block or capture both checking pieces at once. Double checks often lead to forced checkmates.

How to Spot It

  • A piece stands between your attacking piece and the enemy king
  • Moving the blocking piece will reveal check
  • The moving piece can simultaneously capture, threaten another piece, or itself give check (double check)

Practice Tips

  • After each game, review positions where a Discovered Check was possible — either you played it, your opponent played it, or it was missed by both sides.
  • Focus on the key signal: A piece stands between your attacking piece and the enemy king. Train your pattern recognition until you see this automatically.
