and things like double oracle methods and things like that. Yes. All right. So, in terms of head-to-head performance, the really cool thing about this technique is that it allows us to make a really strong poker AI using very few resources. To give you some perspective, we had this bot called Tartanian8 that we made in 2016, which won the Annual Computer Poker Competition, which is competition among poker AIs. It used two million core hours of computation, 18 terabytes of memory, and there's no real-time reasoning.
