It's pretty close. I wouldn't hate a fold, and don't mind the call at that price. Some villains will never bluff in this spot (e.g. with a missed flush draw) when it's still 3-handed on the river, but AT is fairly strong, and it's conceivable that villain could be betting a worse ace.

Yeah it's close.
Small hand sample but -
SB: 102 BB (VPIP: 8.20, PFR: 8.20, 3Bet Preflop: 3.13, Hands: 122)
I'd lean towards a fold.
Also he's betting into 2 players. From my experience that's rarely a bluff.

Seems fine. When you move up in stakes, players in the SB will rarely flat call preflop, and allow you a cheap price to see a flop.

Consequently, as you move up in stakes, you should consider a sizable “squeeze” raise when SB flats, since you are comfortably ahead of the SB hands that flat call, and probably ahead of the CO opening range as well.

As you move up, getting the action so that only two players see a flop is more normal, even when 9-max full ring.

For now, you did fine and will certainly not lose money in the long run when you have such a decent hand facing affordable odds to call.

Perfectly fine. I have no clue if you can make an exploitable fold but as played I don't know if you have many better hands that can call. If you fold this hand, what will you call with? It's a bit tricky because CO can absolutely have some AQ/AJ in his range but at least SB has some natural bluffs like JTs or clubs or whatever.

It's quite small pot with top pair decent kicker, you didn't make it bigger needlessly, I'd say that is a win.

Thanks guys!
