fwiw (and probably not much recently)
I put a nice play on Bogomolov over Koubek. Stats and talent are pretty damn equal but I read Koubek has a bad shoulder at the moment. He will not be able to serve at 100% and his overall game will also struggle.
Personally I was able to find a book which considers retirements losers no matter when they retire.
I know Olympic requires 2 sets to be completed.
