Gawain Jones (White) Puzzle: Fork — Knight Tactics
A knight fork is especially potent in a chess endgame, where fewer pieces make every tempo and loose unit matter. Here, White’s knight can create a forcing check while simultaneously attacking an undefended enemy rook. The checking element is crucial: Black must answer the king threat first and cannot use that move to save the rook. This is a tactical refutation of Black’s active setup and converts White’s extra piece into a decisive material gain.
