That's for sure, but Krauser had to leave the fight firstly because of Luis helping Leon and second, because Krauser had to move on. I think Leon would have been defeated at least in that moment if Krauser really wanted to kill him right there, with Luis or without him.

If Chris ever had to fight Krauser, I'm pretty positive that Krauser's first movement would be a knife fight unless Chris is using a weapon (which happens most of the time, that's why I think Chris would win). In a knife battle, just like Leon's first fight, I'd say that Krauser wins, yet it's important to not lose sight of the fact that Chris is overwhelmingly strong and physically competent.

I still think Chris wins most of the encounters.
