This is actually pretty close. I think either calling or folding have merits and both are fine.
Given you have no stats on villain, it's really difficult to give a more accurate answer. What also makes this difficult to answer is how you have been playing in the BB this is actually quite important, if for example you have been tight and rarely 3B this becomes an easier call because he doesn't want to give the illusion you have fold
equity so doesn't want to raise/fold so I'd for sure put him on quite a weak hand and remove all his better
hands which have us crushed. If you have been 3 betting a lot he would almost always just raise/call off with a stronger hand.
However given it's BvB and it's 15bb, there are antes I think more times than not I'm calling here because (villain dependent of course some might balance) we can take away all his premiums hands for a start. I expect people to take this line OOP with pairs like 22-66 because they just simply don't want to see a flop and it's a profitable shove for sure.
Hands like 77-99 "might" opt for a open shove although this doesn't seem correct, to just open shove. TT+ just wouldn't open shove and if they did, would be pretty terrible. We can also include some suited connections all Ax+ some K9o and maybe some broadways like QJo/KJo.
Vs a 20% range we have 57% equity and with the dead money, being a MTT it is a profitable call based on those assumptions.
