G. Barbier - F. Saavedra, 1895

 El estudio es uno de los más antiguos sobre el tema débil promoción. En toda la literatura ajedrecística no se puede hallar un final tan ingenioso y saturado con material limitado.

El Juego Número 24 Del Campeonato Mundial De Ajedrez 1987

 

Esta partida se centra en el momento decisivo de su cuarto encuentro: la vigésimo cuarta y última partida, disputada en Sevilla en 1987. Tras 23 partidas, el marcador era 12-11 a favor de Karpov, lo que obligaba a Kasparov a ganar para retener su título. En sus comentarios posteriores, Kasparov reveló su plan para esa partida: jugar una partida larga y compleja. La partida en sí no fue de la más alta calidad: Karpov, en igualdad de condiciones, capturó un peón envenenado con 31…♞xa4?, y Kasparov obtuvo una clara victoria. En lugar de ganar con estilo con 33.♕b5!, Kasparov desplazó su dama con 33.♕d1, igualando la posición. Karpov entonces jugó 33…♞e7?.

A continuación se presenta si esa jugada le hizo perder la partida, dejándolo con un peón de menos. En respuesta, Kasparov jugó la opción más segura pero más débil 34.♕d8, en lugar de 34.♗h5!
