PLO100 spewy preflop allin call?

[advis0r]

http://www.pokerhand.org/?1522973

the ep limp/reraiser has AA like 90% of the time (99% after he isolated with his whole stack) so i have to call his first raise for 18.50$ and see a flop with my hand, right? (assuming he will stack off a lot on the right flops)

the shorty calls my initial raise and then decides to raise allin after the limp/reraise. is it a bad idea to put him on AA/KK/high cards he decides to go with?

is it a problem that the one with Aces is the bigstack and the one with the likely worst hand is the shortstack?

B = any big card (A,K,Q,J)</pre><hr />

with the actual hands in play i calculated that i lose 4$ long term, but with all the dead money in its the right call.

put together: is the allin call good/bad/breakeven against their range of AA,KK,highcards? is it likely that i assumed wrong ranges for their hands that can cripple my equity? also keeping in mind the money already in the pot.
