Minor Piece And Two Pawns Vs Rook Puzzle (Rated 1613): Fork — Endgame Tactic
A fork in the chess endgame is especially powerful because the reduced material leaves fewer defenders and fewer safe squares. Here, the winning idea exploits an attacked piece and the activity of the rook on the second rank. The key is to recognize that a forcing pawn move can create a tactical double attack while also improving the rook’s access to the enemy king and loose bishop. This is a classic example of converting piece activity into a decisive material gain.
