Two pair with flush scare - call or raise?

UTG had stats of about 40/5/4 over 40 hands. I'd seen him play his OK hands (< two pair) aggressively, but had no idea how he would play such hands against my reraise, or how he played a draw.

The turn play looks like a draw, but the river bet looks like a bad blocking bet rather than a weak bet from a flush to encourage a reraise, although it still could be because I played the previous two streets aggressively. Call or raise?

Call

I think that I would just call. UTG has a wide range of hands that they start with. So you have to put 2 hearts in that range, or maybe T8, 86. If you raise here, you may be put all in and you have an even harder decision to make.

I think that there is to much danger here to risk a healthy portion of your stack on. ...

Had to make the decision without how many of villains hands have gone to SD, and the % of these they have won.

call becasue you cant stand being raised.

Unless I had a strong read that he donk-bets-calls with top pair weak kicker or something I'm pretty much always just grunting and calling the river...he's not gonna call a big raise there anyway and you sure don't want to be reraised.

Also - that tard bet, call big raise line is often a draw. He could even have T8o here and thus the slightly larger-sized donk into you on the river - since we can't really solidly put him on that by the river, there's little point in trying to push him off it, which probably would fail anyway.

Raise the flop and turn a little more. Call river.

You think he triple donked a flush draw? What minbets the turn

Fold preflop. As played easy call.

My preflop call here was reads based. I didn't have much c-bet fold equity at this table, but I did have good implied odds, and it was unlikely anyone would raise preflop.

I called and beat his drawless Kx bollocks.

For some reason there was a plethora of really bad players last night.
