Four useful checkmate patterns
A familiar mating pattern helps you notice what a position is missing.
Back-rank and supported queen mates
A rook can mate along the last rank when the enemy king is trapped behind its own pawns. A queen beside the king often needs protection from another piece or your king so it cannot be captured.
Smothered mate
A knight checks a king surrounded by its own pieces. The knight can jump over those pieces. Because a knight check cannot be blocked, the defender must capture the knight or move the king, if either is legal.
Check every escape square
Recognising a picture is only the beginning. Verify the checking piece cannot be captured, a line check cannot be blocked and the king has no safe square. An apparently identical pattern may fail if one defender is added.
Try it yourself
Why can a knight check never be blocked?
Check the answer
A knight jumps directly to its destination. There is no line between it and the king on which to interpose a piece.
