Because more times than not KJ is paying off a better hand the whole way. He check raises from upfront, and then gets 3 -bet. What is he beating at this point?

According to Advanced hold'em this is one of the hands that pays off a lot....


He can beat QQ, AQ, JJ, 10-10, He's nearly dead to AK KQ AA KK and all sets.


I'm just going by what sklansky says about trouble hands here OOP....
