I'm working on my GTO game, which is quite the adventure. It's difficult at times adjusting to such drastic changes in theory, such as checking monsters on the river when you want to extract value. Applying GTO can be difficult sometimes because checking your rivered nut flush in a lower buy-in tourney against a weak-passive player that checks back top pair or bottom 2 but would call with them if you bet just eats away your value. I also had a weird situation I'm trying to wrap my brain around regarding blockers: BTN opens and we 3b the BB with like a top 5% range (for this example I'll specifically use QQ or JJ) and the BTN flats behind. Flop comes QhJh6s, giving us top or middle set. We cbet and the BTN flats. Turn is a 9s putting a 2nd flush draw on the board. We bet again and the BTN flats. River is the 8h (completing the flush possibility and the 4-card straight on the board) and we check. BTN jams for 3/4 pot. The solver has us basically snap calling with QsQd or QsQc, but it has us snap-folding QdQc. On the flip-side, it has us usually calling JsJd or JsJc but basically snap-calling JdJc. Holding the Qs would reduce our opponent's bluff combos, not increase them. Also, why would QdQc be a snap fold but JdJc is a snap call? That seemed weird, too.
