I've been improving my game a lot over the past few weeks, but am still very unsure as to how to play in the BB.

I've been struggling mainly with how to steal with 3bets and have no clue when to do it, maybe some of you guys can help me out.

Should I be 3betting with the same hands that I would from the SB? ex:small pockets, suited connectors vs BTN and CO opens, A10, AJ, AQ, AK KQ, KJ, vs early opens? Also what would my range for 3bets look vs the SB open.

Thanks
