Don't really know much about tournaments at all, but curious about this Preflop shove

Blinds are 100/200 no ante
3 handed, top two get paid, we all have around 2300-3k
Bttn raises to 2bb and has like 2500, and has been raising a standardish range it seems
Hero has A8o in SB w 2300

This seems like a standard Jam to me, especially being on the bubble, maybe making people play a bit more tight when facing aggression?
