AA, OOP versus a solid player

Do I need to bet-fold the turn here? My play feels very weak-tight, but I feel very exploitable by betting OOP on the turn.

Villain seems solid, running at 13/10/3.0 over about 40 hands. I don't have any specific notes on this player and he has not yet been c-bet into, so there are no response to c-bet stats. Given his PF play, a set seems his most likely holding.

what am I missing here?

that's a sick fold
I probably tell myself I need to win 25% of the time and call him down

So checking the turn > betting the turn? why?

b/f turn prob vs this guy.

As played I c/c river as the 6 was a good card, it means he flops less sets.

This depends a lot on what you think his UTG limping range is. It probably has a lor of 22-55 in it, and he might peel w/33 making us even money vs. a likely continuing range. B/f the turn.

Yes, this was very weaktight imo. Honestly, he called the flop bet and you shut down with an overpair?
