[00:00] This is probably the best tennis betting strategy, if not the best betting strategy ever. And the best part about it is you don't need to be a tennis expert and analyze the games of hundreds of players. [00:12] This strategy is known as courtsiding, getting on the bets before bookies or sportsbooks have updated their odds appropriately based on the events that have just happened. So how can courtsiding be possible? There has to be an umpire [00:24] who updates a score electronically to a system and that system gets passed onto sportsbooks and they can therefore reflect their odds. So courtsiding doesn't always work. You do need to find slow umpires, which gives you a little bit of time, [00:36] like even a few seconds to bet on the events before sportsbooks can update their odds. So if you watch this clip carefully, we can see there's two parties involved. One is the courtsider because nowadays sporting events don't really like courtsiders. [00:49] So what he does is he communicates to someone and that person places the bets for him. And we can see he's only showing wins and no losses, which implies that he was only betting on guaranteed things.
