Thanks for the posts. Had to record the matches but no Murray when I checked! So that's why! I think that players should get points as the opponent pulled out. Andy is declared the winner so he gets the points.
I think quite a few people wondered what was going on. I agree with you about the points. It isn't Andy's fault Tursunov withdrew so why should he forfeit points, especially as, had Tursunov etired after, say, only one game, he would have been said to have earned them. Crazy.
Incidentally it now transpires that Tursunov cited a right thigh injury as a reason for his withdrawal.
