The bot is trained to play Game Theory Optimal, aka it's playing to be breakeven at worst, which is why I believe it would be hard for a human to beat it. It's not playing perfectly, but the edges it's giving up is so marginal to perfect play that a human is going to lose simply by making a mistake at some point, even if a human were to use a solver to completely optimize their strategy.

Bots have already influenced the poker meta. Libratus showed us how it was optimal to sometimes overbet bluff when you have nut blocker(s). I'm sure when these poker pros do hand reviews, they're not looking at how they can exploit Pluribus, but moreso how they can incorporate some of the lines/strategies it used to beat everyone else.

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.

Is there a way to see the EV the bot is calculating when it's deciding between checking and donk betting? When you place these spots in solvers, they actually advocate for a significant amount of donk betting on certain boards, but pros don't do it because the EV is marginal and it's better for pros to simplify their strategy so they make less mistakes. If you have a flop donk bet strategy, you also have to develop a corresponding turn and river strategy, which makes it extremely difficult.
