I'm actually surprised at how well they play pre-flop (mostly). Did some initial analysis on VPIP/PFR across positions, and somewhat decent.

Post-flop on the other hand is all over the place...

there plenty of published preflop charts and GTO ranges

in fact, a fun project would be take a non-reasoning model, play on a lesser known game format, and see if it learns an "a ha" moment or explicitly simulate moves ahead
