FT$22 - how to maximise this AA?

[Staresy]

Line check please.

Villian won his stack first hand with a weird series of betting on a 45676 board ...

(UTG limps, he raises, all folds, UTG calls - goes check, check; bet, call; bet, all-in, fold), but has been quiet since.

Should I just get it in on the turn? lead out on the turn?

I think a check-raise on the turn gets them in as he is more likely to call a check-raise on a draw than on the river when he misses.

I agree with check raising the turn
