AA with short stack late position limper

[Solitare]

Another idea might be to raise the CO all-in by making a raise to t1100.

The BB may interpret any raise as an attempt to isolate the CO with a less than premium hand. He may call or reraise a t1100 raise as readily as a T400-500 raise. The t1100 raise might get the BB to commit more chips pre-flop to what you hope is a doomed venture.
