What is the difference between strategy and tactics?
Put simple, strategy is what you want to happen and tactics is how you are going to make that happen.
If I were to play against anybody under 40, I know that it is unlikely I would be faster or fitter than they are. So my strategy would be to try to take away their physical advantage. My tactics would be to slow the ball down and use the full width and height of the court.
I need a way to make my skill more important than their fitness and speed.
Easier said than done, of course.
Strategy might include tiring out an opponent, forcing them to make mistakes, rushing them, confusing them etc.
Tactics might include deception, fast, low boasts, more volleys (even at the risk of tiring myself), variety of height and length.
Strategy is more long term, whereas tactics might vary over each game.
There is also the point of yours and your opponent’s strengths and weaknesses.
Sometimes changing your tactics each game is important, but the problem is that knowing when to change tactics and when to stick with what you are doing is more art than science.
Remember, think about the best overall strategy to win a match and then start to consider tactics that will achieve that objective.
