A straight bat is not the only way to improve heel-and-toe combination offensive attacks; master these techniques to also attack with push defense.

This ball friend named Longge said that you play a straight bat with heel-and-toe combination and forehand spin, your backhand only defends with push, how to strengthen your backhand attack and defense.
Many amateur ball friends only play push defense, they only play push defense, which has a relatively weak offensive power, which means they can only defend, it is a more passive situation. Push defense is difficult to proactively attack, at most it's just a squeezed movement or relying on the opponent's speed and spin to push forward.

The traditional straight bat backhand can attack by pulling, but it requires good feel. Straight bat backhand attack and horizontal bat backhand push are different, the horizontal bat push is to hit the ball slightly left of the body, traditional straight bat backhand is to use the wrist to push towards the side.

Generally, amateur players do not have the straight bat backhand attack technique, it is unrealistic to strengthen attack by using defense. There's no way to generate offensive power.
To strengthen the offensive power of the straight bat, you should try to do some push and squeeze movements. For example, when the opponent pushes a ball that is not very spinny, you push and squeeze a downward spin ball, or suddenly squeeze with a slight wrist to adjust the landing point, this is also a way to attack.

Attack doesn't have to rely on dead force to kill the opponent, the landing point and spin change are also a way of attack. Therefore, you can strengthen the attack by adjusting with your fingers, wrists, and changes in spin.

Looking back at what this ball friend said: I'm a little confused. I originally played straight bat with heel-and-toe combination and forehand spin, and also played push and pull defense on the right side. Now I've changed to straight bat and horizontal bat for two years, and I want to change to only horizontal bat and eliminate push defense. After executing for two months, my practical ability is not as good as before when I used to push defense. Should I continue to stick with horizontal bat training?
Wet Father's suggestion is: When you switch from heel-and-toe combination and forehand spin to horizontal bat backhand, you should either just practice horizontal bat and don't practice push defense. There's a process, people have habitual memory or conditional reflexes. If you are used to pushing and pulling, and then you change to horizontal bat and think about pushing again, it will create confusion about whether to push or horizontal bat. Therefore, to completely change to horizontal bat, you must eliminate the previous push defense technique and not use it at all. Once the horizontal bat is mastered, you can only handle the backhand ball with horizontal bat.
Only practiced horizontal bat for two months, it's very difficult to change to horizontal bat within one or two years. At least in one or two years, you need to strengthen the training, and after using it frequently, you will gradually form new muscle memory, which will cover the technical habits and improve.

Generally, amateur ball friends, especially those who are a little older and don't have very high requirements, don't need to change to horizontal bat. In general amateur matches, push defense and straight bat backhand may have more advantages, whether in defense or transition, they have more advantages. Horizontal bat requires finger and wrist support, if the finger and wrist strength is not enough, horizontal bat cannot generate force, but push defense doesn't require much finger and wrist strength, and it's not necessary to change to horizontal bat unless there's a special need.
