Assuming that your github repo is named origin (which is normally the case), 
it should be

git push origin branch-name

or for forcing it,

git push -f origin branch-name

and git will complain if you try and push it to a branch that doesn't have the 
same name as your local one. So, it should catch any mismatch. And the only 
reason that you'd risk pushing to the main repo that way is if you 
accidentally typed upstream instead of origin, and you'd have to combine both 
upstream and master to actually mess with master on the main repo (and since 
pull requests really should be coming from branches, not master, the odds of 
accidentally pushing to master on upstream should be quite low).

If you have to actually push to the main repo, then presumably it would be

git push upstream branch-name

or

git push -f upstream branch-name

though I'd generally expect you to only be pushing to upstream when creating 
branches for releases and whatnot, not pull requests (I'm not sure that you 
even _can_ create pull requests to the main repo from branches on the main 
repo).
