How have you been running lately, pretty TAG or LAG?

If you've been pretty tight over the last several orbits then he might be inclined to look you up with Tx, especially with ATs because IMO raising two limpers like that is screaming QQ+ or a steal and you're cbet on this flop continues to say overpair or bluff. I'd call the turn bet w/ AT because of the implied odds and fold when the river hit and you continued.

Personally, I like the line and bet sizings...if it were with a thinking oppenent
but most at the micros don't have a fold button and if you bluff to the river at this level then you're making a mistake
