Opening up my 3 betting range

[InsideEdge]

Guys

Currently i feel a weakness in my game is my 3 betting, it is something ive been giving lots of thought to but would appreciate others advice.

A poker buddy suggests that against reasonable opponents i should not be 3 betting hands like AQ,AJ, and small - medium pairs. As although you are ahead of their opening range, your not ahead of their calling range. He suggests cold calling against most opponents with these cards.

Currently i tend to 3 bets these hands, if you arent 3 betting this type of hand, what should you be 3 betting? connectors, suited aces etc? Other posters dont seem to advocate cold calling that much at all.

He's has got me thinking a bit as i can see why 3 betting a hand like AQ or 88 would be turning our hand into a bluff somewhat. i.e villian would fold everything worse.

I know everything is opponent specific but would just appreciate some others advice. I kinda caught between two camps at the moment. Either bet or 3 bet almost every hand we play pf, or start cold calling way more with my hands like AQ,KQ, 88-1010 etc.

Thanks in advance guys.
