Today's tip is concerning how to position yourself correctly at the net in doubles. Usually, if you are the first team to get both players to the net during a point, your opponents will either have one or both players at the baseline. Getting into the correct position and covering the court will increase your chances of winning the point.
In general, as a doubles team you need to move together. If you are too far apart at the net, your team will be vulnerable to a passing shot. I sometimes see both players standing too far out wide covering the alleys even when the ball is down the middle of the opponents' court, and this leaves a large hole to hit into. Both players at net are responsible for covering the gap between them, and should be close enough together to reach and cover this area.
Another way to put it, is that your team should be ready for and respect a shot down the middle if you hit the ball to them in the middle of the court. It is unlikely the other team will be able to hit an outright pass cross-court to the outside of the court from there. The other situation then is when your team has hit a ball that is out wide. You both will again need to move together, and both players should follow the ball. The key here is for the player on the same side of the ball to slide over and cover the straight-ahead alley passing shot, while the other player slides over and closes hard on the middle. Your team is now covering the most likely responses of the opposition, and you will force them to hit an extreme cross-court angle shot that stays very low to get by you. In effect, you are playing the percentages by forcing the most difficult shot in a given situation. If the opponent tries a cross-court lob here (which is often a good play when two are at the net), the player covering the alley, who should be further back off the net than the closing middle player, will be ready to attempt to track it down.
When you are in good position laterally, also be ready to close in to the net off of your attacking shots, and back up when you are more on the defensive. When all these things are in place, it is just a matter of executing your volleys! Have fun and good luck on the court!
