77 turned into bluff nl 25 sh

Turn bet is okay I think, mostly for protection. After he called, his range builds up from 2 parts: SD hands, like Tx, 8x, 99, and draws (not sure if he cbets them, because his cbet frequency is quite low).
So, against this range, it's pointless to check/raise on the river. I don't think you can make Tx hands fold, and he wouldn't bet his weaker SD hands. So you don't make better hands fold. If he had a draw, you beat that with a call anyway, but I'd just check/fold with this 4th pair.

Well i am not sure , first this board hits my calling range hard second i would play sets and streiths same way and his low wtsd suggests that he might fold Tx hand and i dont think calling Tx in this spot is very profitable i would fold to .

Would you check a set on the river vs a passive guy to let him bluff/vbet thin? Also, if he has Tx here, that mostly will be AT that I doubt he will fold. Usually it's a bad idea to make fold TPTK type hands, because ppl way more often make bad calls, than bad folds.

Hi.

I prefer check call to checkraise here unless u are very sure that he folds tx here. 2 flush draws missed and u are repping a lot of air here.
