Hi! I started playing badminton 3 years ago in Taiwan. I've had three coaches, but I've always had this problem in doubles. For backhand, I press my thumb on the handle (the flat side), while for forehand, I use the right side of my thumb to press on the handle (the flat side). When defending, two of my coaches has told me to take the backhand grip and defend 3/4 of the area in front of me with my backhand. This worked at first, and with my thumb directly pressed on the handle I can do powerful flat pushes or lifts to the back court. However, there are two situations that I find difficult: Situation A--when a flat (high) smash is hit to my higher-right, I don't have time to switch to my forehand grip, and therefore still uses my backhand grip to return the shot. This allows me only to do a straight push. Situaltion B--When a smash is directed at my lower-right, it is even more difficult. Ideally, I should switch to my forehand and lift, push, or drop. However, when the smash is fast I usually find that difficult and therefore still uses my backhand to return the shot. This allows me only one choice--a straight lift, which leaves us still in the defense. If I can return this shot with my forehand, I would have much more choices, and maybe regain the attack. However, it is difficult to change from my backhand grip to my forehand grip when the smash is fast. For situation B, one coach has showed me a solution. He holds his racket using the backhand grip (thumb pressed flat on the handle), while returns the shuttle using a forehand swing. At first I thought I'll break my thumb doing that, but he does it really well. I was not able to master this technique. About 4 months ago, I have changed my defense so that I focus more on the forehand. This allows me a much better play in situation A--with my forehand, I can immediately turn the defense into attack, since I can directl the shuttle flat or even downwards, and straight or cross-court. For situation B, my play improved also, since I'm returning with my forehand, there is a wide variety of possible angles, and lifting high into the back court is easy. However, the problem now is with my backhand. When a smash is directed towards my backhand, I don't have time to switch to my backhand grip. I can still return the shot with my backhand, but since only the left side of my thumb is pressed against the handle, my backhand is not as strong and I have trouble lifting high into the back court. So I usually do a push or a drop. But after a few games my opponets know and will press forward when I'm returning a smash at my left hand. Two of my coaches said that they don't have this problem since they're using a backhand grip in defense, and the other one said that there is little difference between his forehand and backhand grip and there is always time for him to make the change. But after practicing for 2 months I still can't get it. Does anyone have had a similar experience? Thanks!
