I'm a bit suspicious of COs play here. Has he been limping a lot of hands here? I'd play something like AA, KK, and possibly QQ and AQ identically (though I'd typically raise AQ in this position since I'd rather take the blinds pre-flop with that at this stage).

At this stage I'd probably be folding my TPNK, but then I'm a weak-tight nit far too often, but it also depends on what you think of the CO. What was the average stack size, BTW? What tournament position were you at this point? What sort of table image did you think you had? Depending on these factors I might choose a different time to get all my chips in (especially if it will just steal me the blinds).
