The results of the eight Annual Computer Poker Competition were announced July 14th at the Twenty-Seventh Conference on Artificial Intelligence in Bellevue during the second Computer Poker Symposium. There was a good field of participants.

Three variations of Texas Hold'em poker were played: heads-up limit, heads-up no-limit, and three-player limit. Two different winner determination rules were used to decide the winners in each variant: bankroll instant run-off and total bankroll.

As with previous years, the rules for this year's competition called for matches of duplicate poker to help mitigate the effects of "luck" and more accurately determine this year's winner. In total, about 50 million hands of poker were played.

Each competition has three PDF files with numerical results. In all files, the top table in the PDF is a crosstable including all combinations of matches between players in the given variant of poker. Crosstable entries are the expected winnings, in thousandths of a big blind per hand, for the row player. The second value is the 95% confidence interval around the mean. Cells are shaded bright green/red if the row player won/lost by a statistically significant margin (95% confidence.) Cells are shaded light green/red if the row player won/lost by a statistically insignificant margin. If a cell is grey no data is available for that combination of players (e.g., matches of an agent against itself or an agent entered exclusively under a different winner determination rule).

The raw, uncapped result files have a mixture of instant run-off and total bankroll agents, with no further processing or information. For the total bankroll result files, the second table gives the probability that the row player has a higher total bankroll than the column player. The SUM column is simply the sum of the values in the row, and is NOT used in winner determination. For the instant run-off results, the second table gives, for each round of the run-off, the SUM statistic describing the total bankroll performance of the remaining players.

Statistical confidence was not possible for all results. We have noted all such decisions with a '*'. Please see the section discussing the statistical analysis used to generate the results for additional details.
