Wow, this spot is tough.
To me it's either a shove/ fold
If you call, you are taking the risk of being squeezed by the another big stack.
As you've mentioned, the big stack always limp in
so his hand range is wide
chances of him having sets is relatively small
(you can't be tight after the flop...do you mean passive?)
but a passive player suddenly shown strength means he could have something, probably a pair with decent kicker
not likely to have a draw, because passive player will just call instead of rerasing
I believe your hand should be better than the big stack
Now the foreigner.
His shove can represent many thing.
What does his shove represent?
Since he has only 1500(75BB), a shove here can't be wrong when he has a set
or maybe he's on a draw, trying to semi bluff
It's a close decision, I think I may just fold here, since you are not pot committed, just wait for the huge stack to call and see their hands on the showdown and study their image
