David Pruess Win In 6

At the time his opponent was rated 272 points higher.

No idea, but cool finish. Can you add a later post which gives some lines of analysis?

     Perhaps David Pruess will provide analysis, as I'm not good enough to grasp
all the moves.
     I will see what else I can research.

I was black in this game. I did not see anything better to do than the positional queen sacrifice, but in the final position white has an advantage.

The game was played in a tournament with a special rule that if you knock over a piece and then hit your clock, you forfeit. On the last move my opponent did just that, and an arbiter ran over and awarded the game to black.

That's pretty funny.

My mistake, as I posted this puzzle incorrectly thinking you were white.  I must have lost focus over all the excitement of the millionth member today.

It's still an interesting game.
