The Calibre Of Ace-King...? (Suited or Unsuited)

[Art Vandelay]

If you could somehow totally discount these hands then assuming there are blinds and antes in the pot I'd guess your pot odds would justify a call in pretty much 100% of cases.

I do not know how you can totally disregard AA and KK however.

Edit: I've folded AK before the flop in MTT and it is not that difficult a scenario to see play out.
