In the thematic, the starting position of all games begins with White's third move after 1.Nf3 d5 2.c4 d4. I believe that I tried six different moves from this starting position in the event. If I did not play one of these six, I faced it from the Black side.
I also was the victim of the event's biggest upset, losing with White to one of the players finishing near the bottom of the standings. While reviewing that game this morning, I spotted a key endgame position that I would play differently today with hardly a second thought. Then, I tested my ideas against Rybka 4, drawing the Silicon beast. I also played it against Houdini 1.5, which gave me a slightly easier game.
White to move
Black is set to win a pawn, and there is nothing that White can do to prevent this loss. But, the game itself is not lost.
The game continued:
Here, I opted to keep my bishop on the board (42.Be8), thinking that it could restrain the advance of Black's pawns. Against Rybka this morning, I gave up the bishop and created a light-square fortress.

Black to move
Black's extra pawn is of no value. Only the king can capture pawns, and there is no way to evict the knight from d3 when the bishop cannot cover all the dark squares to which the knight can hop. White's king finds safety on e2, where he is untouchable. Rybka played the position out to move 169, where the game was drawn by the Fifty Move Rule. Black's pawns advanced to f4 and h4 to avoid earlier draws by this rule.
