I know shoving AK is more of a tournament play, but in this case I don't think it is so bad. The only player I'm really worried that might have KK+ here is melano26. Our big raise stands to be called by a lot of hands we're crushing (Ax, Kx) and a lot of hands that we really need to see all 5 cards against (QQ-22). We are likely to be at least a flip against a single caller, if not better, and if we are called by more than that we are almost certainly doing better than 33%. With the dead money that's in there, and the fact that we have to play OOP if called, I don't think a shove is really bad. Otherwise, we can end up check/folding or bet/folding (or betting flop, check/folding the turn) vs hands that we are beating.

By the way:

Code:
Hand 0: 	45.700%  	34.21% 	11.49% 	      21085689 	  7085229.00   { AdKd }
Hand 1: 	54.300%  	42.81% 	11.49% 	      26386797 	  7085229.00   { TT+, AQs+, AKo }
Even against the tight range you laid out, we are 46%. The dead money alone makes this is a profitable play, not to mention the fold equity we have. If we assume the type of calling range that I see more often at these stakes:

Code:
Hand 0: 	56.130%  	49.86% 	06.27% 	      64027068 	  8057085.00   { AdKd }
Hand 1: 	43.870%  	37.60% 	06.27% 	      48281562 	  8057085.00   { 88+, ATs+, KQs, AJo+ }
We are a favorite. And I think we are getting called even wider than this with 4 people already in the pot and the BB yet to act. Our shove certainly looks like a donk bluff, and I expect to see a lot of other Kx hands besides KQs, as well as a fair share of Ax hands.
