well in a way its being cautious, since your prob a head preflop unless there was a big raise in front of you even then i would have to have a raise and a reraise for me to consider folding preflop, i would usually push all in when it came to me since only three higher pocket pairs are out there. With JJ i would love to get it down to one other person not to mention i would love to take the pot down right there. I might get some negitive feedback for this but when i have a pocket pair i love to push as much as i can preflop, most of the time i will bust Ak-A4, since most people belive that Ax is a all in hand, but its not only correct for you to push it in but say you dont get any callers and just take the blinds, its just one bad beat that cant happen and its also gives you a mentallity that you played correctly since you made a small profit. So i guess in away its being cautious through aggressiveness.
