i did every possible mistake there is with pocket pair, from utg raise to limp, to 3bet 4 bet and even shove and call all in... From my point of view it is really hard to fold pocket pair if no action happened before you but often limping with it might work on micros where there is lot of limping and if there are few limpers before you might limp as well but what in the situation where somone bet to isolate the limpers? should you call 2,5 3 or 4 BB and then play OOP and what if you miss the flop im not really EV expert but that smells like -ev I would lie if i say that i fold 22 when im utg and when im early or in the middle if it is folded to me, but i almost always raise, if im at the table long enough and i know that the pot will be just limped ill also limp but that is really rare case, im forcing myself to be more aggressive so i almost always raise, i tend to take a lot of notes on my opponents specially on preflop habits and position and betting patterns and if i have someone who tend to 3-bet with KJo or ATo ill might 4 bet as well to represent the hand lot stronger than the one i have, most of the times i took flop right there or with the continuation bet, the main reason for that is that when the table is tighter i fold most suited connectors i get because im not feel confident playing them, i understand that this is a bad habit but i lost money playing them wrong, anyway that really lower my vpip so when i raise and 4bet (in situation that i have info on opponent) i get the pot right there, of course that dont happen often and i dont pull it on someone i saw playing solid so it worked well for me so far but it is only micros...
