Tough situation with ATs

[LinusKS]

I've never played .25/.50 on Absolute, but fwiw,

I like checking the flop. Against four players, when I've missed the flop with AT, I'll take the free card.

The turn is tougher. My first instinct was to raise, but as you pointed out, even if he has a weaker ace you're splitting here. If he has a better ace, or more, he may three-bet, and if he's donking around with a J (or less) there's a good chance he'll fold.

I like your turn/river plays. Calling down here is the best way to win the most/lose the least, imo.
