Villain is like 20/15/3B:2.5(2/79) Fto3B: 50 SB RFI:44 over 250hands.
I saw him CC with marginal in SB so I could say he is kinda weak/passive rec?

flop: I use half pot CB/Check on this flop.
turn: 5 is bit scary but he could have tons of 2over/st8 draw. Half bet would be fine.
river: 2 is totally blank. With K9, triple could be thin in hindsight because he could flat w TT/JJ, given his low 3B stats(he would also 4B way less here BVB)
His xr jam looks too strong. He could have some full house/straight/trips. I don't think he xr w over pair. And its probably difficult to find enough bluffs... Blocking 9 looks fine but its not enough against his value-heavy xr range.

How do you guys feel with my b-b-b line and fold vs xr otr? Check back OTT also seems to be fine given his relatively strong flat range pre.
Any opinion would be appreciated.

Thanks
