Game 42: Feb 4, 2014

Another game against Eugene.  He decides to surprise me in the opening, and though I'm uncertain if my response is optimal, I think I held my own in the opening.

Later on, I'm up a pawn, but he's got the B-pair and a passer in compensation.  He attacks and I defend well initially.  However, a blunder on the 31st move decides the game.  I need to analyse that move for alternatives which might have saved the position.
