Van Geet Opening Berlin Gambit Fork Intermediate Chess Puzzles

The van Geet Opening Berlin Gambit is an offbeat opening that often begins with 1.Nc3 and can transpose into sharp, tactical positions where a fork decides the game. For an intermediate player, this theme means recognizing moments when a knight or pawn can attack two valuable targets at once after the early gambit tension. The defining feature is the unusual early development that leaves central pieces and the king vulnerable to tactical forks.
