My plays are based off custom database I've developed (ATP matches, books prices, performance stats) that I use to identify price discrepancies and adjusted according to recent news (rss, tweeter. I'm competent in 3 languages). I also have been playing tennis for several years and had a chance to discuss the game with pro players and coaches.
Of course, there are guarantees in this biz, use this thread only as a source of reference.
I'm doing my trading on betfair, so some of the prices or "lay" plays may not be available at the books. Most of the plays will be without detailed write-ups.
So, let's give it a try and GL to everybody
