Some regs at 200z are 3betting 22-88 vs utg and mp minraises, both ip and oop. This seems really bad to me, since they're not pushing and equity edge by any means and have a profitable flat vs minraise in most situations. I guess they're worried about getting squeezed, but they're creating a situation where my continuing range >>>>> their 3betting range so I doubt it makes up for not getting squeezed. And they can always get cold4b. Then again when someone does this when he's closing action from bb there is literally no benefit.
Only viable option I could see if 3bettor thinks he has such an edge on opener that he chooses these hands to isolate.

Any thoughts?
