8th place

[stillbr]

Well I've decided to start posting hands where I bust out in 8, 9 or 10th where I feel I might have made the wrong move..

So here goes...
Level 3 I get delt KQo in the SB with a stack of 650 after posting. Folded around to the Button who raises to 175. He seems reasonable, I have no real reads on him. I havent seen him do anything weird or stupid.

Anyways.. I push, BB folds, Button calls with AK.

I'm out in 8th.

Is this a bad push? Too early/too aggressive?
