$6.5 - AK vs shove over

[mattiesmat]

Is this an easy push?
I did not have reads, because PAHUD was doing weird.
Notice that MP2 called my raise and is left to act.

PokerStars No-Limit Hold'em Tourney, Big Blind is t50 (9 handed) by Hand Converter CG

Against unknowns, I shove over with all the dead money in the pot.

Fairly easy shove to isolate imo.
