good read gone bad?

stars 100 nl, everyone folds to me on the button and I raise w/ ATo to $3.95 trying to be tricky. both blinds call.

flop is 4h Th 2c, they check. i bet 9, sb mini-raises to 18, bb folds, I call. I got Ah. I'm thinking he's thinking I got AK and just fired a value bluff bet. I think he's got anything from top pair to a flush draw. pretty sure I got him but I want to see what he does on the turn.

turn is Jc. he insta-pushes in for $63.55, I got him covered. I don't think the Jc helped him so I go with my original statement and feel like he's trying to push out AK or AQ w/ his top pair weak kicker or flush draw + pair or whatever and somehow 'know' I'm ahead...
