Hands From Level 4

I lost 17,000 chips with QQ vs. KK, this was a cooler but possibly avoidable. Had 77 vs A8o, the guy made a bizarre shove that I called but lost the coin flip. Down 7,500 chips with 22 vs ATo, the board came xKJ x A. I bluffed the river which would have worked but the guy caught his ace. Now down below 4,000 I got the last of my money in with A9 vs AJ and didn’t get lucky.
