Clarification about rules

1. It is legal to hit any part of the hand with the racket in it. As long as it doesn't double bounce anything, like rubber and hand.

2. You can bounce as many times as you want on your opponent's side. It is higher level play to have it bounce twice on their side and low.

3. This is a legal serve and an ace, if by side you mean the top side edge.

4. If you hit the opponent and he is leaning over the table, then it is your point. If the ball goes outside the area of the table, then it is their point, regardless if it hits them.

5. don't understand the question. If he hits the ball and it is off the table, it is still his point.

6. It is hard to drop a high and deep lob with topspin. There is a possibility that their drop shot will be too high. And the opponent will run in for a easy ball to kill. It is easier to just keep on smashing and try to win the point. If they drop shot, they are inviting them back into the table and taking away their advantage. Of course there are some pros with good dropshots like Ma lin,  or decent like ma long. They drop the ball short and then hit back deep and move their opponents back and forth and left and right. I've seen some pros like Hao shuai or chen qi try to drop shot and there is too much topspin in the lob to stop the ball and it bounces off the table.

Thank you for your expert (and quick) answers.

Sorry my question was not clear. Let's imagine I am the server. I see the opponent court as a rectangle with 3 edges: left, middle and right. I make a service where the ball goes in diagonal. It bounces once on my court, once on the opponent court and exit the opponent court on the right edge while he was expecting the ball to go out by the middle edge.

Is it a legal service, and in case it is, is it considered "not nice"?

I smashed the ball and totally missed it. The ball goes completely out of the opponent court and hit directly the opponent bat. Does that count as my point (which means the opponent had played and missed the point, whether he hit the ball intentionally or not). Or the opponent won the point (which means, I have missed the court and the opponent didn't play the ball intentionally).

The scenario is more complicate when the ball just missed the opponent court by a few centimeters. By reflex, the opponent strikes the ball back and missed the point. FOr the sake of argument, let assume that the bass was about 10 centimer above the table. close to the end edge of the opponent court. By not letting the ball drop on the ground, the opponent made the job a little bit difficult to judge the fault. I just want to know how such a situation is judged by official rules.

Thanks  Kenney for your help. I think I get it now.
