Candidate Master, right?

I just realized a way "with" could be right. "I played this awesome game with a CM, in which I won."

I think everyone was trying to correct your English (Sattwik), but I figured out how it makes sense.

"I played with him."
"I won with him (as my opponent.)"

So while it is not most common--- the misunderstanding makes more sense if one sees the thought process behind the words. However it makes more sense and is more acceptable grammatically if you add the indefinite article "a."

So, "I won with a CM (as my opponent.)"

And for it to be truly correct you should include "as my opponent." Or else to use 'versus' etc.

I just think it makes more sense to look into the sentence and understand where they were coming from.
