That's what was my feeling before these semis and now it is even stronger.
Rock, Paper, Scissors being Djokovic, Nadal, Federer on this surface.
For each of the three one is a bad match up, where opponent's strength has no match, and your strength is mostly neutralized. And one is a good match up. Where it is the opposite.
Djokovic loves high ball, and dislikes someone who has a better forehand and who has the skills to match pace with pace.
Nadal likes to play those who can't consistently hold his forehand assault. And dislikes those who can, as that takes out his single most important weapon.
Federer likes pace, likes opponents who depends on receiving high ball, as no one can bring the ball low down as well as him. And dislikes to play those who can kick it high to his backhand.
Rock, Paper, Scissors.. This game goes to Nadal, it seems
