When betting on tennis, you need to be aware that the rules on how bets are settled can vary significantly between bookmakers. In particular, this applies to tennis retirement rules - ie what happens to your bet when a player retires or a match is abandoned?

It's important to know because, if you bet with the wrong bookies, you could end up losing both of your bets - the back and the lay.

**Warning - These terms are correct at the time of posting this. If unsure of the rules, you should ALWAYS check them for yourself (use the links provided below). If you do find any changes, then please let us know via support.**

Generally, bookies can be put into three different groups with regards to tennis rules. Note that these rules only apply to betting on the winner of the match, and not necessarily to other markets.

You can use the Profit Accumulator **Dutching Calculator** to dutch bets between bookies with matching rules.

**Tennis rules type 1 - Bets are valid if one set is completed:**

With this category, all bets are valid if at least one set is completed in the match. All of the exchanges fall into this category, so if you're backing a tennis bet with one of the bookies in this group, you can safely lay your bet on one of the exchanges.
