Yes I play 10/20 live multiple times a week. Explain to me how a winning reg would ever consider calling a 5 bet all in with 54o and then fold KK pre to a 4 bet?
As for KK, what's the hand history like? Again, heads up or multiway? Might have a read? What are the bet sizes and stack sizes?
Im not wasting any more time talking to you and i stand by my previous statement that you dont know what you are talking about.
Also, Fedor Holz once won a major tournament shoving a similar hand a few years back.
