In the paper we include a graph of performance over the course of the 10,000-hand 5 humans + 1 AI experiment that was played over 12 days. There's no indication that the bot's performance decreased over time (there is a temporary downward blip in the middle, but that's likely just variance). Based on discussions with pros, it sounds like they didn't find any weaknesses and they didn't seem to think they'd find any gi…

I think it would be hard for the pros to find exploits against the bot, but they could definitely lose less. When using solvers, pros generally only input a couple of sizings for bets, and avoid 2x+ pot sizings, which from the video it seemed like the bot used at much higher frequencies than other pros.

I think it took the community a while to come up with the right algorithms. So much of early AI research was focused on beating humans at chess and later Go. But those techniques don't directly carry over to an imperfect-information game like poker. The challenge of hidden information was kind of neglected by the AI community. This line of research really has its origins in the game theory community actually (which i…

So will this be the end of online poker?

Any chance of the code being released or a cepheus style answer key being provided? http://poker.srv.ualberta.ca/strategy

I don't think the poker world would be happy with us if we did that. Heads-up limit hold'em isn't really played professionally anymore, but six-player no-limit hold'em is very popular.

> you don't need to adapt to opponent weaknesses to win at poker at the highest levels that may be true for limit poker, but in a no-limit tournament the best this bot could do is not lose. as the pressure increases with the blinds and the players are forced to bluff and call bluffs how does this bot avoid folding itself to death from a run of bad cards? I could see this bot doing well at cashing but I don't see how…

I couldn't find it confirmed in the primary or secondary article, but I would bet the bot is just playing cash at a fixed stack depth rather than a tournament; just like in the wild, bots are much more of a problem in online cash than online tournaments. Dynamically adjusting strategies by stack depth, number of players, and pay jumps, would probably be several orders of magnitude more complex.
