Based on this thread at least, seems like Alex is clear favorite. While anything can happen, my prediction is not only does Tony win this one, he does it convincingly, very possibly 6+. Heard it here first.
As someone else mentioned I almost think Tony might be better off playing Alex even as there is some chance he lets the fact that he is getting spotted get in his head, or he could even go the other way and think there is no way he can lose with that spot which results in either complacent or dumb play. Should be a fun one to see how it goes.
