$1k WPT sat hand

[Ulysses]

$1k live sat. 86 players. 3000 starting chips. Top 8 get $10k WPT seat + $500. 9 and 10 get $1000 tourney seat.

27 players left. Blinds 400-800. You are in SB w/ about 20k. You are #2 in chips at the table, guy to your right has about 25k. Both of you are among chip leaders. Nobody else at the table has over 10k. Most players in the tournament are pretty bad.

Folded to MP who goes all-in for just over 6k. You have played with him for 45 min or so, a few orbits. He pushed on the button after a limper and in the BB after 1 limper, both times no call. He pushed once from EP and was called. He showed ATs that hand and won. Other than those three hands, he has folded.

You have 99. BB is going to fold. Call or fold?
