I guess it's a trivial spot, however it always puzzles me when I have an overpair below let's say QQ on a low board. Some time before this one happend another guy cold called with QQ and took the pot (different table). Mindset is alos something I am tryng to work on. Anyway....
Except of 3x there's only 99 and TT that have me beaten since I assume he will 3bet pre with JJ+ AQs+ AKo, so I decide to call. He looks fishy but his bet of 50% pot OTT doesn't look to me as a bluff, however if we assume he will defend BB with 36% he has only K7s, A7s, A3s, 77, 33 and some connectors with 7x that made actually a strong hand. However he still has no made hand about 60% of the time, and A high 23% of the time.

Do you call here till the end and just make a note if he calls on BB with his usual 3betting range as well?
