This won't work I assume. Also it's heavily theoretical.

If you cause a buffer overflow in an internet service running with administrator
privileges this might indeed cause a system access with root rights ( or the
Windows equivalent).

But I am really quite sure that potential crashes of your movei chess program
don't fall into this category for various reasons. I can imagine an attack
against Movei running on a chessserver - but how is this threat going to be
worked on to threaten someone's computer?

I know there are some people reading here who can give *much* better advice (
they usually have Chinese names from experience ;) ) , but I don't buy the
danger caused by movei bugs for now.
