1) No lets.
If the ball touches the net during a serve, play on.
2) No infinite deuces.
After the 4th deuce, the player who wins the next point wins the game.
3) No infinite tie-breakers, except the 3rd set in best-of-3 matches, or 5th set in best-of-5 matches.
If the tie-breaker is 10-10, the player who wins the next point wins the tie-breaker.
4) Wimbledon
In Wimbledon, tie-breaker determines all sets, except the 3rd set in women's championship match, or the 5th set in the men's championship match.
Justification: In the middle rounds, if the 5th set score is 70 games vs 68 games, the winner will be so tired and will have no chance to win in the next round. If the 5th set is of regular length, the winner will have a chance to win in the next round.
