1/2 NL B&M - how bad is this push

[timtowdi]

1/2 NL B&M at a local casino. Assume all opponents are terrible and capable of having any 2 cards. Just wondering how bad my turn push is, thanks.

Stack sizes:
UTG - $250
UTG+1 - $500
HERO - $320
BUTTON - $250

Preflop:
Hero has: Ac As

UTG raises to 10, UTG+1 calls 10, Hero rasies to 50, Button Coldcalls 50, UTG Folds, UTG+1 calls. (3 to the flop)

Flop: Ks Qh 2s (Pot: $173)
UTG leads for $75
Before I act, Button says "I CALL" and now what started as a close muck turned into an all-in push to try to take the potential $75 in dead money from the button. So I go ahead and push to make it $270 to go.

I read UTG's range to be AK, KQ, or a FD type hand.

Thanks.
