Firstly, it was KQ.

Secondly, i thought I was ahead of Kitty. I nearly popped it preflop but thought I can check and inspire the shove on the flop if she has missed, and I can get away if it comes Axx. Plus your range was huge for a raise preflop, perfect time to squeeze with a raggy ace or medium pair. I figured I was at least 65% vs one of you, and maybe 45% vs the table
