I'd agree with all that Creme, except that up till RG Novak was undefeated, so to speak.
He knows now, as it were, he can get beat. And he will be fully aware of how in form Roger is.
Not sure he's played a properly on form Roger, has he ?
Will be tougher than he thinks, I think.
I think if you asked Novak he'd naively say he'd want to play Roger, as Andy has beaten him at Wimby.
Again, all psychological. And I think Roger would have the upper hand.
