Meanings of マジできる


Yesterday, I was in a Japanese online game (囲碁) forum and before a game
started an opponent asked me:

[code]

    あんた、マジできる？
    
[/code]

I only know マジ as a colloquial way of emphasis, so I couldn't figure this out.
Was he asking me if "I'm any good"? It also turned out that he was very bad at
the game - to a degree where he probably didn't know the rules. Maybe he was
asking me if I knew how to play?

Can someone please explain how the マジ fits in there?




This sentence is ambiguous, and can mean both of the followings.

  * Can you really play go?  
(マジ means _really_ (not lying), できる means _can play_ )

  * Are you (in fact) a very good player?  
(マジ means _really_ (emphasis), できる means _competent/good_ )

Before you play, if an opponent doubt you know the rule, he may say this in
the first sense. After you showed your good go skill, the same opponent may
praise you using this phrase in the second sense.

Well, if I were in the same situation, I might ask the meaning. -- どういう意味ですか？
ルールを知っているかという意味ですか、上手かという意味ですか？
