Well, you don't want to get sucked into making a second best hand in a big pot where you have to pay off, so I don't think it's this clear cut. Any info about the opponents? It's interesting that the six is willing to threebet vs. the ace. While this is probably a good plan for him given your 7-doorcard, I haven't seen many players willing to do this even at the higher limits. So it would be nice to know if you'd seen some other hyperaggressive play from this person.

At any rate, I lean towards a fold.
