SB - Hero - 150bb
BB - 150bb

Hero Qc Td 9h 6c

Hero raises to 3.5bb, BB raises to 9bb, Hero calls

Flop (18bb) 3s 4s Tc

check, check

Turn (18bb) 3s 4s Tc 9d

check, Hero bets 14bb, BB raises to 60bb, Hero raises allin

Villain is a decent reg, tight most of the times but versatile, and sometimes goes on much more aggro style for a period

At this moment he was 3betting a bit higher than usual

Preflop

std i guess

Flop

Well, he uses to cbet a lot (except very specific boards), and with à 60% pot sizing

This flop doesn't hit his range, but it's a flop low and not that drawy, and he use to cbet often here
When in check on such a flop, I'm waiting him to try a c/r here

Anyway, I don't have such a good hand to bet it and make him pression (TP w 3OC + BDFD) and check would be std even in vacuum I would say

Turn

He checks again, DP max now, let's bet for value/protection on such an heavy drawy board

When he c/r.

Well got DP max here with a board non-straigthy, non-flushy

But the SPR is quite high (>10 before I bet)

Could have some sets sometimes : TTxx connected (TTJQ, 9TTJ), some pp+pp that made sets etc. But i'm holding 9Txx, and so 99xx/TTxx are fewer in his ranger

Could have massive draws too (KQJx+FD), or some hands which were trapping on the flop (KKxx/AAxx + FD) and still can be c/r here for value (putting me on a draw on this turn, and still having big equity vs DP etc...)

Reraise shove this turn seems me logical, but the SPR is high.
Calling ip could make sense, but I'm not waiting many card, he can complete so often his draws, and if he bluffs on brick it'll be difficult to be
The good thing would be that he would shove on my outs (9/T)
