Mate In 2 Puzzle (Rated 1144): Spot Mate in 2 — Pin Tactic

This puzzle is a classic middlegame mating net built around a pin and a forced reply. White’s pieces coordinate to attack the enemy king from the side, not by brute force, but by using a rook lift and a tactical line that leaves the defender helpless. The key idea is that one piece is overloaded: if it moves, a critical square becomes vulnerable and the king is exposed to a direct finish. In classical chess, these are the kinds of patterns that decide games quickly.
