25NL - AA hits set on turn, what does villain have?

[KAT21]

Thanks for the responses. Lesson learned. I completely missed the 45 possibility until he called the reraise, which is pretty bad. The rest of the hand went like this.


Hero re-raises to $22.75, Villain calls.

River (board: Ts 3s 2d Ad Kh):

Hero bets $10(should have just pushed as he's not folding). Villain goes all-in for $17.75.
Hero calls.



Showdown:

Villain shows 5d 4d.
Villain has 5d 4d 3s 2d Ad: straight, five high.
Hero mucks cards.
(Hero has Ac As.)
