In the German Chess Amateur Championship 2024 on August 1, Oleg Derr’s move Rad1 overlooked a crucial opportunity to apply pressure on his opponent. Instead of taking advantage of a superior threat, he chose to defend an attacked piece, which was already sufficiently protected. This move also missed a chance to reveal an attack on a key piece and did not improve the mobility of his bishop. Additionally, Derr failed to use the move to force Bongardt into a defensive response, missing out on a potential winning tempo. While Rad1 did develop a piece for more active play, it ultimately did not address the opportunity to enhance the position or develop more effective threats.
