White pieces, I went on the attack in the eleventh game with the Ruy Lopez, exchange variation.  Again like prior games as white, I got a decent advantage, but failed to follow through, resulting in a draw.  In game 12, we saw another Scotch game, though this time I had black.  It took a long time, but double passed pawns ultimately led to the victory.

Game	1	2	3	4	5	6	7	8	9	10	11	12
Zurahn	½	1	1	0	0	½	½	1	½	1	½	1
Chessmaster DS	½	0	0	1	1	½	½	0	½	0	½	0

Chessmaster DS will now require to win 4-straight without a loss in order to take the match.  I hope to finish it off with a bang tomorrow.  As white, I've drawn 4 out of 6, including my last 3, so it's time to make some headway here with the advantage.
