All these spots are hugely read dependent, paying attention to what size/how often/what position people raise in can really help illuminate things in these spots. Would be a much tougher spot if SB was also at ~10 BB, then taking a confrontation against the big stack really sucks unless you're pretty much crushing his range. Button would probably need to be raising ~ 65-70% to go to war in that spot with AJo. You're probably ~ neutral $EV with the stacks as they are and range described, so player's privilege. Though in a lower buy-in, people are more likley to spew in future hands and freeroll you into the $$ if you fold here. How loose/tight the two big stacks are in calling pushes (i.e. yours), and/or does 3rd place stack fold/complete his SB (to your BB) are other bits of info (among many) that would be nice to have in making a close decision here.
