10/20:River nut flush,villain leads out and I just call on paired flop

[an0nym0u5]

BB had TT for full house.

I probably should have included some reads/notes/previous hand experience.

SB donks a lot of hands on flop when he has a piece of it. Flush draw, weak pair, one pair, two pair, set. He even goes for turn check raises after donking flop sometimes.

SB also pays off a lot of hands on river after lots of action when pot is medium-big. Bottom pair, mid pair, A high.

Given that knowledge, I thought he would overcall in a spot like that.

I didn't see SB's hands, but I'm assuming A4s, I think he would have 3-bet with a pocket pair preflop.
