Under what conditions do you make this play and why? I’ve mentioned several times that I play overpairs weakly a whole lot… But I’m curious how this looks. I’ll explain my reasoning for the fold later (not like it's rocket science or anything...). But my question (looking at the hand on paper) is why would I ever fold here?
