Dry pot KK facing UTG+1 shorty push

Standard?
Or is it better to push over the PF raise and save a line like this for AA?

This looks fine, I'd probably just shove in the heat of the moment though.

Please try to play with UTG+1 as much as you can.

Given your stack size I push preflop, if there is another call then you have less than 1/3 of the pot on the flop so you have no real decisions postflop and your opponents will know that. If they are going to call that raise PF they are going to call your push a good percentage of the time, Id rather get it in as a favorite preflop than not being sure where I am on the flop but with no real choice.

Just shove, don't get greedy.
