i'm betting a bit bigger on the flop and turn, flatting turn raise is fine since you have double blocker to KT and 9T probably won't raise.

i think villians river line is pretty meh, i don't see regs bluffing here ever but your hand looks weaker than it is, they could have worse for value.

I just have a habit of making everything smaller in btn/blinds & hu hands/pots postflop, dunno if thats a leak or not but I'm just accounting for my preflop range being far wider than usual. Any thoughts on that/if theres any reason to worry about that?

well on some board textures, opening wider preflop is gona make your cbet range stronger postflop.

for example if we opened 40% on the cutoff instead of 30%, i think that would usually make our range more suited cards heavy. So after we barrel a montone flop we are slightly more likely to have more flushes in our range.

i think i'd adjust my barrel sizing based on how often i barrel and not how much i open preflop.

but we can't adjust it too much, because the reason i'd make your flop size and turn size bigger is to make money. We don't make much money when we barrel turn with $10 into a $16 pot and villian has 89. Our sizing has to be enough so that they don't have good odds, plus a little bit extra so we make money on top of that.

i thought betting close to pot in hu is optimal
