New tournament with lots of different AIs

[TracySMiller]

Defenchess makes it a perfect 5-0 with another flawless endgame. After a flurry of exchanges, it emerged a pawn up, so quickly forced trades to get the remaining pieces off the board and win the endgame in a true Karpov/Petrosian style. Defenchess is now a win/draw away from joining Arasan in the FINALS.

Defenchess cruises to the FINALS with a drubbing of the mighty DGT Centaur. The Centaur allowed Defenchess to takes its b7 pawn. Soon, the a7 pawn fell, then a pawn on the other side of the board, then another. Defenchess forced a trade of Queens and never looked back, winning the match 6-0, setting the stage for the Arasan vs Defenchess FINAL, which will be Best of 12. Should be a fascinating match, sort of a Fischer vs Karpov matchup.

Hi Tracy,

Nice win for Defenchess!
Any idea what its elo is?

Regards, Paul

Defenchess is around 3270, but Arasan should win the Final as it’s graded above 3400.

The finals gets underway with a squeaky clean draw. I don't think either side ever had more than a 0.5 advantage, and by move 30 it was clear this was a draw. I played a few more moves just to make sure, but the draw was never in doubt. Has the mighty Arasan finally met its match?

In a master class on defense, Defenchess somehow survives Arasan's two passed pawns to procure the draw in a Sicilian Defense. The match is tied 1.0-1.0.

In yet another miraculous game, Defenchess survives an Arasan assault on its naked King and is forced to give up its Queen, then proceeds to trap Arasan's Queen and forces a repetition of position to keep the match even at 2.0-2.0.

In the following position, White (Arasan) plays 26. e6+ to win Defenchess's Queen.



But Defenchess traps the White Queen, which can't escape the Rook attacks:

Arasan draws first blood in Game Five against Defenchess. Arasan emerged from a complicated exchange in the early middle game a pawn up and played a flawless endgame to earn the win and take a 3.0-2.0 lead in the match. Defenchess resigned after the 91st move when it finally saw the forced mate.
