What are the skills of CS throwing grenades?

About the use of grenades and flash bombs. Novices often can't master the essentials of bombing, or hurt themselves, or blind one of their own teams, and are often scolded to death by teammates ... Here I talk about the use of grenades and flash bombs:

A, in CS, there is a very special algorithm for parabola thrown by grenades, that is, I will count my moving trajectories together at the moment before throwing. Therefore, when you need to throw a Grenade in the left passage of the T-shaped passage in front, you might as well use the left translation just before throwing it, so that you will find that your Grenade can be thrown deeply. Similarly, when throwing grenades in the right channel, the right translation is adopted.

B, if you need to throw a Grenade in a far area, you can throw it out at the moment of jumping, which will throw it far away (but it is likely to explode in mid-air, and even the other party will not touch a hair).

C cherish grenades and don't throw them about. There are many experts who will save grenades until the last minute, and their judgment is very accurate. When it thunders, one person (even several people) will die. However, for the fierce mini-map battle, some players still need to throw grenades like the enemy's exit channel at the beginning of the battle to "bleed".

D, flash bombs can also be used to cover their retreat. For example, if you retreat to a corner and the enemy is chasing after you, then you can take out a flash bomb and throw it at your feet, and you turn a corner ... If the timing is good, the situation will change immediately. Sure, okay? Who can't play blind? Hahaha ... In addition, when you suddenly meet a large group of enemies, you can throw a flash bomb at your feet, and everyone can't see it, hahaha, hahaha. ...
