Richard is the highest ranked Frenchman in his half of the draw so a good chance he will be on the Philippe Chatrier court for his 1st round match. Nadal most defiantly will be on there. Murray who else on that side of the draw and the 4th seed will probably on the Suzanne Lenglen court.
Richard doesn't get much of his matches on the PC court so if he does play his R1 match there, it would nice!
I can easily imagine him asking to play on Lenglen, + his match is against a qualifier.
