Indian Defense Pyrenees Gambit Puzzle (Rated 978): Fork — Decisive Material Gain
This opening puzzle shows how a single forcing check can create a decisive material gain. White’s queen jumps into the attack while Black’s bishop on b4 is overextended and the kingside is still underdeveloped. The key idea is a fork-like tactic: one move can attack the king and a valuable piece at the same time, forcing a defensive reply that leaves the loose piece vulnerable. In classical chess, this kind of move often turns a small initiative into a winning position.
