KK early in $5 + 1, did I overplay it?

I've been playing SNG's for about 1 year on UB exclusively and have been a winning player. I decided to try out Party and am trying to adjust my play accordingly.

Early in the tourny, no real reads. I can't get bisonbison to work so here goes. Hero is UTG.

Was the turn all-in way over the top? I thought he had an Ace and might go for it.
