T9s 3-bet pot

Since villain just called your 3bet from these positions, I see mostly just draws on this board. So I guess betting turn is fine.
OTR 78 got there and some slowplayed sets are possible. Could it still be ok to make a thin valuebet and hope villain calls with some weaker 9x or pocket pairs? We would also avoid being bluffed.

I think as played villain has some busted draws too that he will shove. But our hand is not strong enough to catch him. You played this fine.

Preflop SB vs BU, I rather flat call T9s following Janda, but Snowie 3bets it so it must be close and playable either way you feel it.

OTT I'm not even sure I understand the question but it usually doesn't make sense to bet "not to get bluffed"
If you don't wanna get bluffed, why not check/calling ?
(That said as played I like barelling this turn, you need to keep going to reduce his floats' rentability)

OTR understandable fold, what can he bluff ? There's more chances to go against TT than 88 or A9 than A6-89
Of course there's the busted flush draw but not sure it makes lots of combos in his 3bet cold calling range here.

The 3 bet preflop is too big. Postlop seems ok. AK shouldn´t bet OTT if u check.
