'Thus far, superhuman AI milestones in strategic reasoning have been limited to two-party competition. in Carnegie Mellon's Computer Science Department as a research scientist at Facebook AI.

'Pluribus achieved superhuman performance at multi-player poker, which is a recognized milestone in artificial intelligence and in game theory that has been open for decades,' said Tuomas Sandholm, Angel Jordan Professor of Computer Science, who developed Pluribus with Noam Brown, who is finishing his Ph.D. In another experiment involving 13 pros, all of whom have won more than $1 million playing poker, Pluribus played five pros at a time for a total of 10,000 hands and again emerged victorious. Each pro separately played 5,000 hands of poker against five copies of Pluribus.

It's one of the most fundamental poker skills. However, one step further is also thinking about your perceived poker range, so it becomes their range against your range versus their hand against your hand. A TAGfish would not usually think about their own range. But this is important because your opponent will play according to what they think you have. How to Put Your Opponent On a Range in Poker.How (and Why) Thinking in Ranges Improves Your Poker Game.So your perceived range is also about what you’re representing.

You may internalize that continuation-betting just once is bad, so you just fire every second barrel, without any balancing, or the opposite, c-betting once and then just giving up. You may even learn that three-betting light is profitable, but not that you shouldn’t do it regardless of your opponent's three-bet calling frequency. Or you may even do it with the wrong poker hands. Serial continuation-betting (c-betting) and continuation-betting once and then giving up are signs of a TAG fish.Ī TAG fish tries to learn to play better poker - watching videos, reading articles, studying the game - but misapplies the information learned. Isn’t this most of us? Let’s explain with examples. You may learn you can float the flop and take pots on the turn against players that c-bet too much. However, you end up floating with pure air instead of gutshots or hands with backdoor possibilities. In other words, you only learn half the skills - you know what to do but not when, how and against who you should be doing it.Ĥ. You Play Similarly from Different PositionsĪ TAG fish may treat the cut-off and the button as the exact same position. If an opponent raises from early position, you can’t always call with 6 9 from the cut-off just because you'll be playing in position.

You've still got one more player to act behind you and if they’re good, they can make your life hell. That player can three-bet with impunity whenever you call with your weak, speculative hand. They can call and steal your post-flop position and they can punish you after the flop. Where good TAGs abuse the button, a TAG fish allows themself to be abused by the button. Alternatively, you may also be playing too loose from the blinds - perhaps over-defending your big blind. Or playing too wide from early positions (wide referring to your range). If you think you’re going to win an opponent’s entire stack every time you hit the nuts, that’s a TAGfish mentality. You end up calling with speculative hands post-flop, or check-folding when you miss.
