kind of a weird spot here because the BB being auto-all-in does 2 things to the hand.
1. the CO should be pushing tighter than usual because he is guaranteed to go to showdown.
2. the lower BB gives you worse odds.
Still, I dont think AQo can ever be a fold here against the CO range. I expect him to be pushing at least down to A6/A7o, not to mention all the Qx broadway combos that you crush. I think im calling ATs/AJo+ against a reg (especially a good reg).
and pokeraddict is correct, our risk-aversion here is quite low considering our joint 4th chip position with the reg chip leader to our right (who will be pushing into us a lot).
so over-all pretty std call for me.
