AA in WSOP 5k event

[Bond18]

History: A round or two ago i jammed 15 BB's on the CO with 77 because antes are high and the SB and BB both had big stacks and kind of liked cold calling which could be a disaster. Other than that i've been pretty tight.

Online i think this is a bit more clear, live i'm not so sure. The table actually has a lot of aware, observant, and competent players for once, so they will likely find an UTG std raise, limp, or 2.5X raise suspecious. Then again, this is live where people have no idea about shoving ranges and take all in's quite seriously, though a couple of players on the table (matt24, nordberg) had considerable online experience.

10 handed table, i am UTG with 4400 and AA. Blinds 200/400 with 50 ante. BB is Daniel Aliai, who is somewhat short.

Whats our play and why?
