In one sentence, describe what the following article is about:

When you're playing a new opponent, whether it's at a competition or during a friendly game at a family outing, you should assess your opponent's game even while you're warming up. You should look for a few main things: if your opponent is more of an aggressive or defensive player, if his forehand or backhand is his dominant shot, and any weaknesses, such as slow footwork or weak drop shot returns, that you can exploit. Don't hit all of your shots to the same location of the court of your opponent will be able to predict your next move every time. Instead, mix things up by hitting a drop shot followed by a shot to the baseline, or by moving your opponent from the right to the left side of the court. Moving from the front to the back of the court is particularly tricky unless your opponent has very nimble feet. Many players are weaker on the backhand side, so try shooting toward your opponent's backhand and see if this makes your opponent return less shots. If so, continue to exploit your opponent's backhand. Your backhand is the left side for right-handed players and the right side for left-handed players. When you're up at the net, simply hit the shuttle short, just barely over to your opponent's side. This will make your opponent run and will catch him off guard. This is a great technique if your opponent is positioned near the back line. If your opponent knows that you are going to do a short shot, you need to flick the shuttle over the opponent or to another side and if you didn't do this, your opponent will fly the shuttle near the back line. If your opponent hits the shuttle straight at you, hit the shuttle in a different direction instead of hitting it right back at your opponent, where he will expect it to go. This will work especially well if the shuttle has generated a lot of momentum. If you're quick on your feet, you can change the direction of the shuttle and not give your opponent enough time to react to a fast-moving shuttle. If you have mastered the drop shot, then use it to make your opponent run all the way to the front of the court. Then return the next shot all the way to the back of the court. Not only will this force your opponent to be quick on his feet, but it will also catch him off guard. This is also a great way to tire your opponent. To do a drop shot, hit the shuttle lightly so it just crosses the net. If you like staying near the net, serve short, hit drop shots, and do whatever you can to make sure that your opponent can't hit the shuttle to the back line. If you're more comfortable at the back line, then serve long and hit speedy long shots so your opponent doesn't have a chance to move you toward the net. Make the opponent lose all control as you play your style of game and maximize your strengths.

Summary:
Understand your opponent's game. Make your opponent move around the court. Shoot toward your opponent's backhand. Hit a simple short shot. Change the direction of the shuttle. Hit a drop shot followed by a shot to the back of the court. Make your opponent play your style of game.
