a deal is a deal is a deal...
If Slavik knew about your deal with Aga and then pursued the domain knowing you would be left with nothing then I would agree that he did not handle fair and he should be blamed for having bad business techniques.
However there is a possibility that he didn't know and in that case he can't be blamed. After all I think it's Aga who should get the shitload for backing out of an agreed deal. If I were you I'd sling some mud on NetPond
