river bruff in 3bet pot oop

BTN is pretty tight 19/16, but CO is a huge fish so he could definetly be iso´ing fairly light. I dont think I have sd value a lot when he checks the turn. Thoughts on my play and river betsize?

mehhh ur line doesnt make that much sense. if you think hes got T9/TT/JJ or w/e a lot then just barrel turn. from his perspective, hes going to question why you wouldnt bet the awesome 3 turn if you have a value hand.

if theres a hudge fish in the hand wouldnt we just want to call even oop to take it multi way?

I prlly wudda flatted 89s there even OOP and play with the fish in the pot since 89s does play pretty well postflop. Wudda 3B hands like T8s/79s if I felt button was isolating and maybe folds to 3bets often enough. I like the flop Cbet but once you checked the turn, I think C/F river is better than B/F. I would either C/F or B/F turn, but wouldn't bet river.

point taken as for preflop. although i think im not that much more profitable calling since i just suck postflop, especially multiway and oop.

anyway i didnt plan on taking this line when i checked turn, i was basically giving up, but then couldnt resist when it got checked thru. would anyone take this line for value w/ AK/KK IP?
