400NL - In which I float the flop in a 3bet pot

[willw9]

Villain is acesfull2833, running 22/16/3, probs 2p2. I've been fairly splashy this session, especially preflop. This is the first time I've flatcalled his 3bet in position.

On the flop I'm repping all sets, AK, AQ, and AJ. When the A hits the turn, there isn't much value in betting the aforementioned range, so I continue with the act and check it back, intending to shove all rivers as I would with the above. He bets, and I happily fold, having avoided possibly stacking myself on the turn trying to fold out KK/QQ/TT and still having maintained a plausible line for a plausible range.

Thoughts?
