Could someone run yesterday's Vote Chess game through a strong analysis program (i.e. Rybka so something similar) so that we can see what happened?  The game is here:

We were up an exchange, and I thought that we were winning, but at move 31, we traded the exchange away for a position where we would be up only one pawn.  We could not win in this position and had to settle for a draw.

I was in favor of this trade, because I was afraid that their two passed pawns would be too strong otherwise.

I thought we were winning, but looking back, I think we were overly cautious, even before move 31, and we gradually gave up our winning chances. 

However, I would like to see what the computer, and perhaps some experts, have to say about the game.

Nobody in this group owns a chess engine that we can analyze this game with? 

Kacparov,

Which free engine do you recommend?  I would like to try it.
