Are there any ethical considerations relating to the prospect of use of this bot for cheating in real-money games? Either from your internal team or after public replication?

We're really focused on advancing the fundamental AI aspect. We're not here to kill poker. The popular poker sites have quite sophisticated anti-bot measures, but it's true that this is an arms race.

Are any papers available yet? Is the bot going for game-theory-optimal play, or trying to exploit weaknesses in other players?

The paper is here: https://science.sciencemag.org/content/early/2019/07/10/scie...

It's going for game-theory-optimal play. It doesn't adapt to its opponents' observed weaknesses. But I think it's cool to show that you don't need to adapt to opponent weaknesses to win at poker at the highest levels. You just need to not have any weaknesses yourself.

The article makes it sound like the AI is trained by evaluating results of decisions it makes on a per-hand basis. Is there any sense in which the AI learns about strategies that depend upon multiple hands? I’m thinking of bluffing/detecting bluffs and identifying recent patterns, which is something human poker players talk about.

The bot handles each hand independently. How the players play in one hand does not affect how the bot plays in future hands at all.

That said, it did train by playing against itself (before the experiment against the humans began).

Can you share some about what strategies the bot prefers and how these compare with common professional human strategies?

We talk about this a bit in the paper. Based on the feedback from the pros, the bot seems to "donk bet" (call and then bet on the next round) much more than human pros do. It also randomizes between multiple bet sizes, including very large bet sizes, while humans stick to just one or two sizes depending on the situation.

How long until a slightly worse version of this model is reverse engineered and appears at every table in online poker?

Slightly worse versions are already out in the wild. Bot using the published technique will be live in a couple of months tops.
