Algunos de los jugadores más notables de la historia como Anatoli Karpov, Tigran Petrosian o Viktor Korchnoi sobresalieron en este campo e incluso hicieron de la defensa una parte fundamental de su estilo.

En “Ajedrez de los GM: El Arte de Defender” se estudian los procedimientos defensivos más importantes (simplificación de la posición, juego restringido, devolución de material, etc,) así como la manera de enfocar, razonar y resolver los difíciles problemas que se presentan. Además se tratan algunos aspectos psicológicos (como la tenacidad, las posibilidades prácticas o los cambios de tendencia) sin olvidar aquellas situaciones donde la mejor defensa es un buen contraataque.
