Lederman, Leon vs. Kiefer, Gerhard - FIDE World Senior Team Chess Championships 65+ 2024 0-1

In the game between Leon Lederman playing with the white pieces and Gerhard Kiefer playing with the black pieces at the FIDE World Senior Team Chess Championships 65+ on July 11, 2024, the move Qb7 by black exhibited a complex mix of strategic decisions and missed opportunities. The move threatened a material gain and defended an attacked piece, which is now well protected. However, it also overlooked a superior opportunity to create a more potent threat and missed the chance to reveal an attack on another piece. Although the move forced an opponent's piece to relocate, thereby gaining a tempo advantage, it failed to find a better escape from an attack and missed the opportunity to escape the attack entirely. Moreover, it did not take advantage of a chance to defend an unprotected piece, nor did it provide the best possible protection for an under-defended piece. The move also overlooked an opportunity to force an enemy move and a chance to develop another piece for active play. Despite developing the queen for active play, the move missed the chance to create a stronger defense for an unprotected piece.
