I just played a $55 satellite for Caribbean and blew my stack on first hand.

Initial raise from cutoff of 600, a re-raise from button to 1,200, call from SB of 1,200, I make it 7,200 with AQ from the BB. The cut-off folds, button folds and the small blind calls. Flop all low small blind checks and I check.  King on turn, small blind checks and I shove. Villain calls with the hand I was representing AK and I’m out… just awful. I should have shoved flop if anything. How to blow  $55 in a minute and why am I cold 4 bet re-raising  AQ?
