What NOT to do in your chess game:
First, DO NOT resign! EVER! Your opponent could make a FATAL MISTAKE, and you could WIN.
In this position, black goes for Qa2??, but then, white goes Rxh7#!
Second, NEVER get sidetracked. It doesn’t matter if Karpov is watching. HEY, YOU, WATCH YOUR CLOCK! Never go for unnecessary complications.
