If I wouldn't know he had 88 I would put him on this range
Spoiler

So his equity would be 60% and mine would be 40%.
We know he had 88 so his equity is even lower it's 52% and mine 48%
For simplicity I expect SB to always fold.
Odds are 28.6%
Does this mean that my fold here is quite a big mistake and I should call here? Because my equity is 48% which is bigger than the given odds?
