Betfair tennis: bet on 2 players at the same time?
I use betfair and there is something that I don't understand...
Is it possible to bet in a match (for exemple Janko vs Ilia) on both players? Like I put 2$ on Ilian , and 2 $ on janko?
Because it seems possible... But if that happened, I would be always winning something so it's weird...
