Turning my set into a bluff?... 2/5

-Villain in this hand was unknown at the time
-I'm never sure what to do on spots like this on the turn? I'm obviously not folding, but I'm not sure if raise> call
-On this river I feel like a lot of his range will fold to a push, and even a T might fold since the flush got there as well

i think i would just raise the turn.

river looks good he doesnt look like he has much. i would guess maybe some kind of 2 pair or something. on the river you think he would bet bigger if he actually a 10 or a flush.

fwiw i see this play from randoms with draws quite a bit so he has flush some reasonable % of the time

I feel like I can't reply rationally to this spot right now since for the past month or so everytime I push here villain has the nut flush

im probably folding the flop.

i fold the flop here mostly but i think you have to raise the turn. so many bad villains bet like 1/4-1/3 pot with FD's so i think i raise to charge it.
