Folding AA to river push on checked turned 3 flush? NL25

[SubaruSTiMike]

Villain is 43.33/16.67/1.31 over 60 hands.
I've been playing pretty TAG, raising and taking down a lot of pots, maybe he got fed up? Someone in the chat said "caught". Is this an easy fold?

Do you guys call the flop instead if raising? I was pretty lost. BB could have been on any draw (flush or straight) which both hit, and I don't see AT playing this way or any hand that I beat. Although his AF was pretty low, I don't know if he would have raised draws. He did miniraise/call.

I think my line would hae been better if I called the flop, check behind on the turn, and call a reasonably river bet?

have you seen villain do anything dumb yet? fwiw if the table thinks you're way out of line he could be taking this line with a pair or something thinking you won't call or were just trying to bluff the flop.

but yeah this river is a tough spot, i don't know what i'd do here. probably call, but that could be very wrong

I think he was making a stand or had a set he would have bet the turn and if he had an overpair he'd have raised you preflop.

Your read of straight and/or flush draw looks spot on. If the turn card had missed him he probably bets there to try and take the pot down. He hit his flush or straight and checked hoping for a check raise, or that you'll call his bet on the river. I fold

Looks fine to me.

looks like A8 of spades to me.
