Due to the short timeframe we had to prepare for the competition, we simply used a combination of two Sparbot programs (PsOpti4 and the new PsOpti6). The second place finisher was Teppo Salonen, a hobbyist programmer who built his own version of Sparbot for the Poker Academy software platform.
A highly-publicized entry from Carnegie Mellon University did not perform up to expectations, losing to the U of A and to Bluffbot. No doubt the talented researchers at CMU will be back with a strong contender next year. Their new program will also need to play substantially faster to maintain the normal pace of Limit Hold'em. The special slow event (one minute per game) that was created to accomodate the CMU entry may not be repeated in future tournaments.
More details of the event are available in this press release, and at the competition website. A full analysis of all matches will be performed over the coming weeks.
