Counter Check Checkmate Puzzle (Rated 600): Countercheckmate — Chess Endgame Tactics

This puzzle shows a classic chess endgame tactic where the side to move uses active rook play to punish loose pieces and the exposed king. White’s queen and bishop look dangerous, but the position is tactically unstable because key pieces are undefended and overextended. The winning idea is to force simplification while removing the opponent’s main attacking pieces, turning a seemingly sharp middlegame into a favorable endgame with decisive material gain.
