Sergey Karjakin (Black) Puzzle: Blind Swine Mate — Net
The blind swine mate is a powerful rook-coordination pattern in which two rooks invade the opponent’s seventh rank and trap the king behind its own limited shelter. In this chess endgame, Black’s king has weakened cover and too few escape squares. White’s active rook on the seventh rank, supported by the second rook and the knight’s control, creates a mating net that leaves the defending pieces unable to intervene.
