the range of hands that you 3 bet when you are able to isolate and play heads up is much different than when the table dynamic is that of getting 3-4 cold callers of your 3 bet. i find this happens a lot in live games. so of course you want to go for pure value. what type of hands push your equity in games like this? middling rundowns like 6789ss? or mainly looking at high card combos and nut suits.
