CHANGE OF PLANS At what point do you have to go further and actually change strategy? It varies from match to match and player to player. If you want a specific point in a match it’s this: when you’re down a set and a break. That’s not always the time to change, but it’s a good guideline. You may have lost the first set in a tiebreaker and then lost serve because of great shots by your opponent. This is still a close match. But if your opponent won the first set easily and is doing the same in the second, you better change. Wait much longer and you’re terminal.
