Match tie-break

• An extension of a tie-break (played instead of a deciding set) in which the winner is the first player to reach 10 points and lead by a margin of 2

Championship tie-break

• Same as a Match tie-break but only called "Championship" when played in a Final. 

Sudden death deuce

• If the score reaches deuce, it's a sudden death point.  The receiver chooses which side to take the serve on.  This also applies in doubles with the receiving pair deciding who receives the serve.  However, the pair cannot change positions.
