A45 Trompowsky Attack (1.d4 Nf6 2.Bg5 e6 3.Nc3 Be7 4.e4 Nxe4 5.Bxe7)

This was played in a team match called May Madness Open Starts 1 May 15 1201 AM PST). The match was played between Obsessive Chess Disorder. and KNIGHTS of the REALM. I played on board 5 for OCD and lost both of my games against BryantPark despite being given some chances to win, for example, I could have won the game below if I had understood that 26...Rhc8 still has winning chances. Somehow I did not even thought about that move all that long and chose to play 26...Rab8? instead which gives my opponent a slight advantage. While that move should not lose the game, it does put me in a more difficult position. Other members of OCD were doing much better than I on their games and we won the match with a score 38.5 - 33.5!
