The Power of h4- Part 2

It's been a long time since I posted my first power of h4 article, but I've finally summoned up the courage to post another one.

Anyway, here it is. Polugaevsky initiates the greek gift against tal-but in an somewhat unorthodox setting. It takes a few subtle pawn moves to make the difference, and soon it is clear that white must win.
