med hand in BB facing a small open with $5 drop

Theoretically BB is suppose to defend more facing a 2.5x open because of the good price but with a $5 drop the spot is very marginally.

3betting doesnt seem appealling, especially when there is no fold equity. Playing a bloated pot oop with a wide range is just a losing prop.

Calling the bet for a 20ish% chance of winning $10-$20 doesnt sound appealing either.

Im on the edge of just wanting to throw my blinds to the guy and move on to the next hand. Keep the money on the table for a chance to get it back(That how some players think, not sure if its correct).

But then they can just open small with inpunity, and you will bleed slowly.

I guess we can counter with a couple of lite 3bets and fire a cbet to get them to stop. And this circles us back to playing a bloated pot oop.

Im really not sure what to do here.
But I got a game plan for when im in late position and it folds to me. Just open small and steal with inpunity.
