Playing $25NL I got KK all in PF 3 times
The hands I was up against:
55
88
AA
I couldve folded against the AA as I 3 bet from the blinds and the UTG raiser 4 bet shoved. But, his range has QQ in it enough that getting nearly 2:1 on my money I had to call. By the time we 4bet we have so much of our stack in that it would be a horrible play to fold.
