88 v KK 3 left final table

[stever35]

I am dealer. 3 left, all roughly equal in chips. I p/u 88, raise 3xBB, SB folds, BB goes all in. He was tight passive. There is now 1.4 million chips in the pot and I have 800,000 left, Blinds are 50 & 100K. 3rd paid $1684, 2nd $2464, 1st$ 4423. If I had won I would have 2.2 million in chips versus 1.1 million. I came in 3rd

What is the statisical probability of an overpair to 88 when it is three handed?

Should I always lay that down, or because it's three handed, call anyway?

Give his pushing range as probably TT+ AJ+ and KQs this is a -EV call and I don't think it's close.
