In theory I'd assume all of our options are reasonable:
- Call probably isn't bad, but I tend not to do much calling with offsuit Ax OOP in these sub-40BB spots - I will have some calls but probably hands like AJs-AQs, maybe some middle pair type hands.
- 4-bet all-in or even 4-bet click back has some merit, too, especially if we think we're getting stuff like 99-TT to fold.
- Folding isn't unreasonable either
In a $500 freezeout, against a player I don't know, I'm probably just folding here. I think if we were somewhere closer to 50BB I'd like peeling more, but even then I'd probably lean towards using this a click back to balance out my QQ+/AK stuff.
