Dead money in this case means you need 47.4% equity against the opponents shoving range. If up against AA, KK hero has 23.1% equity. Against AA, KK, AK: 40.2%. Against TT-JJ, AK: 48.4%. Absent prior reads (shipping light, playing AA, KK slower to extract, player steaming etc) this is a fold imo. Potentially expensive way to get notes on people.

Or maybe I'm wrong and noone plays AA, KK this way (huge overbet shove) hoping instead to build a pot with them always and only overbetting the "strong but vulnerable" like AK itself.
