Theres plenty of situations.
One cool way of seeing if u can
call is to determine what he needs to have in order to make a
call break even.
Like, you need about 44%
equity against his
range to
call this. If you dont know why, go
back to spoon's 'how to analyze calling an all in".
if the BB only has aces, we're 12% to win. Nope, that doesnt work.
if the BB only has
KK+, we're 23% to win. Nope, cant
call here either.

if the BB only has 'xxxxxxx', we're >44% to win.
Ok sweet. So if we're guaranteed that he has a
range that is wider than what you found xxxxx to be, then we can
call and not worry about it.
But if we're not even sure he has this range, we should probably just fold..because he has to have all these hands for it to just be breakeven and
variance is gonna kick us in the ass anyway.
One thing of importance is how often you think
villain 4bets. Over 22 hands, he's likely not to have done this yet and i
fold and not think much about it.
However...if hes been crazy and 4bets and 3bets and
open shoves and thats all he does (unlikely since hes only raises twice according to the
stats) its a pretty easy
call.
