Well for my pocket pairs i first have to see where i am on the table cuz if im under the gun with just a low pocket pair depending on the blinds i mite just call the blind and see what happens from the rest of the players but on a high pocket pair i raise if im under the gun becuz u are most likely going to be called by one of the players that is going after u. Second u have to consider ur chip stack compaired to others becuz if ur short stack and the big stack is the next to act u have to push it all in and hope that he doesnt have a higher pocket pair becuz then u'll have the advantage going into the flop. I relaly play all my pockets differently even if they are the same one sometimes i try to catch a flop sometimes i dont i just try to mix it up...i also have a story that happened to me just a few minutes ago about my pocket aces. well it we were 4 handed and i was under the gun i raised double the big blind hoping to get a caller and i did...flop ended up being 7, j, ace and i was ecstatic he was first to act and raised all in so i thot great im going to double up but then i saw his cards and he was on a flush draw i was hoping so bad for no spades but he caught one on the river and i lost a huge amount of my chips....
But when playing pocket pairs just consider ur position, chip stack, and the different ppls styles around u
