Need a second opinion...

I'd fold because the villian probably won't be playing for his whole stack against the only player at the table that he can lose all his money too. I also don't think it's worth calling 50x BB when you'll be able to call much less most of the time. The 5/10 rule applies to standard raises (re-raises), and obviously 50xBB is not the standard raises.
