I know that I would never fold KK preflop to a shove but at what point can you start to think about folding your pair... if it is QQ or JJ does it make the fold easier to do?
It depends on the situation and the opponent. There are people I see at the tables all the time that I would never fold JJ to in any situation, and other people, mainly old guys, that Ill lay down QQ to 90% of the time.
