doing your homework is elementary. My pre match selection was Djokovic. He has a stronger serve and he is a better return player than Nadal on hard court.
I backed Djokovic after 1st break of Nadal at 2,3. You know, at mens tennis, one break can mean winning a set, so i decided to back only with a small stake (5€) and put more on Djokovic, if he lose the first set. He breaked back and won easily 6-3, 6-2.
After winning first set i layed Djokovic to minimize risk and to get an opportunity to back him again at higher odds. Nadal called for the trainer and a traded out to avoid lower profit caused by retirement.
