Very tight player is 21/5/1.2 over 80 hands. No idea what UTG had but i was positive I had him beat. He'd raise if he had 2 pair or better for sure.

Based on the type of player and the flop action I was pretty sure I was beat to an overpair but called anyway.

I guess I was looking for my 5 outer but really didn't know if a fold made sense at all.

What do you guys think?
