If you are right about him, then you can win.
If you offer to bet him something substantial, and his W/L statements show a win, then he'll do it. 
After all, he's betting $15K a hand on baccarat not knowing what will happen. Why wouldn't he bet you $15K on a sure thing?

 You're accusing him of lying. If you're so sure that he is, then throw down...what are you waiting for?
