a couple things:
1. At move 25 you didn't look all that hopeless to me. I thought you had some counterplay. 2.The sac was a really cool idea. 3. Your opponent misplayed in the ending rather a lot. You had him rattled, for sure! 4. to quote mr.Dal, Nicely done! 5. Here's my idea for drawing the game after the sac.
I recently played a 3 day/move CC game in which I seemed to be dead lost, with a material disadvantage and a bad position. However, I managed to create a passer that eventually gave me a won position. I thought it was a pretty interesting game. The crucial moment is at move 25, so if you just want to take a quick glance you can skip there. Any comments?
