Pin Puzzle (Rated 2356): Defend — Check

This middlegame puzzle tests defensive calculation when your king is exposed and the opponent’s queen and knight are highly active. Black has a material advantage, but White’s active pieces create immediate tactical pressure. The key idea is to respond to the check while preserving coordination and limiting follow-up threats. A precise king-safety decision transforms a dangerous position into one where the defender can withstand forcing play and retain practical winning chances.
