FIND EVERY LEGAL CHECK
How to see checks you keep missing
Checks are forcing, but they are not always obvious—and they are not automatically good. Learn an ordered scan that finds the quiet queen check, the distant bishop check, and the discovered check before you judge any of them.
Why “look for checks” is not enough
A beginner may remember the instruction and still inspect only the queen. Checks can come from a capture, from a rook on the far side of the board, or from moving one piece out of another piece's line. The useful skill is not remembering that checks matter. It is searching every mechanism that can produce one.
There is an equally important warning: forcing does not mean good. A pointless check can drive the opposing king to safety, abandon a defender, or trade an active piece for nothing. Separate generation from evaluation: first find every candidate, then calculate the reply.
The king-outward check scan
- 01
Knight jumps
From the enemy king, inspect its eight possible knight-attack squares. Is one occupied by your knight, or can a knight move there legally?
- 02
Contact squares and pawn attacks
Look one square around the king for queen or rook checks, then inspect the two squares from which your pawns would attack it.
- 03
Rays toward the king
Trace ranks, files, and diagonals outward until the first blocker. Could a rook, bishop, or queen enter that line, capture on it, or already attack through it?
- 04
Move the blocker
If one of your pieces blocks your own rook, bishop, or queen, ask whether moving it uncovers a discovered check. The moving piece may create a second threat too.

Find every check.
It is the displayed side's turn. Click the checking piece, then its destination square. Find every legal checking move—not only the best one.
Do not stop at the first check
The first visible check is often not the best. After generating all checks, compare the opponent's legal replies: can the king move, can the checking piece be captured, or can the line be blocked? Under the FIDE Laws, a move that leaves your own king attacked is illegal, so pinned pieces may not be valid checking candidates.
Give special attention to checks that also capture, create a fork, or restrict the king. Double check is unusually forcing because moving the king is the only way to answer both attacks at once.
How to train checks without learning “check addiction”
Use exercises that ask for all legal checks rather than one tactical solution. This improves candidate generation. Then review each answer and say why it is safe or unsafe. In a real game, run the same scan for your opponent before your own moves; defensive check awareness prevents just as many losses as attacking awareness creates wins.
Keep the drill short and exact. Five minutes of accurate scanning is more useful than a long session of clicking the first queen check you notice.
