Bubble BCP

I make a deep run and played well considering I had an aggro donk to my left. I made a sick read with my AQs. I min raise UTG with 25BB and the villain just smooth calls. The flop was rainbow low cards I Cbet and he calls, turn is a queen I check he bets i click it back he smooth calls. and I check fold to his shove and he flashes KK. Gameflow just sent alarm bells off cuz it was exact hand I put him on. But later down on the bubble and I was middle of the pack I have KJ and just limp from EP just intending to fold facing any heat on most flops. I get smooth called again by a solid player. of course I flop a jack and just decide to open shove becuase I have the best hand most of the time and of course the player snap calls with AJ the only hand I obviously am crushed by... make 11th out of like 480 ish players... making a whopping 0$
