Don't really bet or know tennis, but seems like only way to go is taking big dogs, or maybe throw favs into a parlay. Even that seems dangerous though lol, saw azarenka on my site today at -800 and she's on her way to losing in straight sets. How often do you play smaller units on 400+ dogs?
I agree that you have to bet bigger dogs and smaller odds in a parlay to win..I am doing a lot of game handicaps and i try to find sometimes favourites who to cover a certain number in odds close to even,i personally don't like parlays as it kind of missing them by 1 match etc.
Finding big dogs it's not easy,so you would need more than stats or head to head between 2 players,it's hard..Indian Wells is being disaster for favourites all around,but simply can't go with bigger odds just because they are so tempting..if i can't find a reason to go with them i don't.
Sometimes better cover yourself of losing a match,as for example Errani lost 2-6,7-6,6-4 to Jelena Jankovic and i had Errani +4 games @ +108 Odds for outright win for Errani was over +175 and even +200 a opening,but sometimes it's better to outgame her and keep it close for a player in a match whitch will suit you good and doesn't matter who wins in the end..
Best of luck:toast:
