Honestly, you kind of need to be more specific with your question, like giving a situation or something like that,
That being said Ill try to answer ur question kind of.
It really depends on position or the amount of BBs oyou have in a tourney or sng. Late position I am raising any pair 44-AA, unless there has already been a raise,in which case I'll either flat or threebet depending on the hand and opponent. Early position I might double the blinds or limp/call a raise if you getting decent odds to set mine out of position.
Shortstacked in a mtt or sng however, if you have less than 10-15 BBs I am open shoving almost any pocket pair especially when you have position.
