I'd call 1 and fold 2 pretty happily.
In 1, if he has 44-88 and 87s, we have more than enough equity and that never acounts for dumb ass spazz with air or some other hand he has no idea how to play like 99 (not that these are likely) but yeah it's closer than I first though but I'd still call.
In 2 you're just crushed.
