In live poker, I sometimes play at a 10/10 NL, 3000 max buy-in game. Almost everyone buys in at 3000, so effective stacks are 300bb deep almost always.

The games are full ring, frequently 10 players.

I have often wondered if we should have a 4betting range in these games pf. Has anyone else had this problem?

I'll explain the difficulty I have right now:
-I usually play in 100bb games, so I dont call 3bets when I am oop, I either 4bet/fold.
-If I start calling 3bets when oop, I feel that I will have holes in my range if I also still 4bet. Say I start 4betting KK/AA, then when I call 3bets, I am pretty capped.

Any suggestions for dealing with 3bets oop pre? So far it seems ppl are saying it is just too hard to balance to have a 4bet range at all pf.
