The limp-raise all in? What's his range here? Final table...

[thesilkworm]

$8,500 guaranteed $69+$6 6-handed double stack MTT on Full Tilt. Final table has been in progress for about 15 minutes with no casualties. Everyone seems to be able to play, and there have been quite a few steals and resteals, but as yet, no all in showdowns. This was the first time I'd seen anyone open limp at the final table:

Stack sizes:
UTG: t91398
UTG+1: t39154
Hero: t113323
Button: t83148
SB: t74029
BB: t84948

Pre-flop: (6 players) Hero is CO with Q[img]/images/graemlins/heart.gif[/img] Q[img]/images/graemlins/diamond.gif[/img]
UTG calls t5000 <font color="aaaaaa">(pot was t11100)</font>, UTG+1 folds, <font color="#cc0000">Hero raises to t20000</font>, 3 folds, <font color="#cc0000">UTG raises all-in t90798</font>, Hero ???

Is his range here really just AA/KK? I've seen this move made by middle pairs and AK quite often, but is he really doing this against the only guy that can bust him?

For what it's worth, this is the payout structure:
