Calling an all in with 54, what are the stack sizes? How many players? 54 has better hand equity 3 or 4 ways than heads up.

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?

Clearly you have not done your due diligence if you dont even know the most famous hand. It was a 3 way all in and he called with 54o and both players happened to have AK

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.

Yes, calling 54o 3 way is loose but not crazy. Maybe I've just played too much PLO over the years.

Also, Fedor Holz once won a major tournament shoving a similar hand a few years back.

Calling allin 54o 3way is loose, crazy and extremely losing play in the long run. You have no idea what you are talking about. Some tournament shove has nothing to do with this.

he regularly makes this play tho. it's not like he has three lucky hands. he has 3000 of them
