What happens to bets if a player retires or is disqualified in tennis?

Matched betting on tennis carries some risks that you do not find in other sports. This is because of the way that bookies settle bets in the event of a player retiring. Some bookies will void all bets, others will pay out on the player that progresses to the next round.

If you are matching bets between a bookie and Betfair, it is important to understand the rules, otherwise you are exposing yourself to risk. The same goes if you are dutching between two bookies.

This thread shows how each bookie settles bets in the event of a retirement. It also shows which bookies are compatible with each other for matched betting on tennis.
