If a match is for whatever reason played on a different surface, other than the one published initially by the tournament officials, Blackbet reserves the right to consider the event void.
If one of the players listed to play withdraws or is disqualified before the beginning of the match, the bets will be considered void. If he/she retires or is disqualified after the start of the match, the opponent will be considered as winner, and all other bets will be considered valid only if they would have already been determined at the time of the interruption, otherwise will be considered void.
If a player withdraws or is disqualified before his/her first match of the tournament, bets relating to that player winning the tournament or reaching a certain phase will be void, otherwise they will stand.
In a double, if at least one of the four players retires before the match, and his partner decides to take part to the match with another player, all the bets placed on the event will be considered void. If a tennis match that is meant to be played “best of 5″ is played “best of 3″, all bets placed on the event are void (i.e. in a Davis Cup round where the winner is already known, both teams can decide to play the remaining matches best of 3: in this case, all bets involving “shortened” matches will be void).
