Improve Your Chess: Subtle Mistake - Giant Turnaround
Opening: B22: Sicilian Defense - 2.c3
Black makes a couple mild mistakes in the opening which adds to a clever White win - if he can find it. White gets the general idea but the move order wrong, making all the difference. Finally White, with both sides playing too fast (as often the case), either hallucinates or gets frustrated and tries a terrible sacrifice. Black correctly defends and White is totally lost, resigning at just the right time.
