13. 0-0 is definitely bad for white, but not losing. And what do you mean by "winning fork?" Even if white's light squared bishop wasn't protected twice, he or she could have played 14. Bf3. After that I'd say you are better off than white, but you would still have to be careful. "It is rightly said that the most difficult thing in chess is winning a won position." - Vladimir Kramnik.
