Queen's Indian Capture Defender Chess Puzzles

The Queen's Indian Capture Defender is a motif in the Queen's Indian family where one side meets the opponent's queenside setup by capturing on c4 or b4 and then defending the captured point with a piece or pawn. The defining feature is the tension around the c4 square, often after ...Bb7 and ...Nf6, when Black aims to win time by taking and holding space on the queenside.
