My preferred pocket pair is QQ. If i were in the begin of the tournament, i always do 3 bb + 1bb (1bb for each limp in the table) for they go out before the flop i dont wanna a lucky guys in the same pot as me. If i'm in the bubble, i go all in, ever time a had a pocket pair and suited cards if i here in position and a have a good stack at this moment, because a lot of players are afraid to get they allin in this particular moment.
