Dilworth attack – positional pawn sacrifice

Aseev – Mikhalevski , 1999

Black to move

28 … d4! was the best move in this position. White was threatening to fully consolidate on the dark squares (maybe bring the knight over to c5), so black had to create counter play as soon as possible.

After a few moves this position arose:

Now Black king will threaten to invade on light squares, so the White knight won’t have time for Ne4-c5xa6. Black got reasonable counter play and drew the game.
