ATAQUE DESESPERADO EN LA ESCOCESA

Hace unos 30 años Kasparov retomó la idea de emplear la apertura Escocesa contra Karpov desde entonces muchos análisis e idea han surgido en esta clásica apertura. En 2015 se revivió la variante Mieses en la Escocesa por Morozevich y Nepomniachtchi quienes introdujeron la jugada de ataque 8.h4 como si ese fuera un intento de Ataque Desesperado. Sin embargo es un serio movimiento contra el que las negras deben estar atentas ante las diferentes ideas.
