Talking about the technical points of crossing the line of fire

There is nothing to say about marksmanship, you should "practice"! It's okay if your opponent's marksmanship is not good, and it's okay if you're a good marksman.

Tell from experience (I have been playing cs for years, and I am definitely an amateur):

Try to jump out when you flash out (AWP only). It is still difficult to get rid of it. Not everyone can get rid of you! The rest depends on whether you can kill your opponent.

If the other side flashes, there are only two possibilities: jump; avoid

To deal with a jumping sniper, you can move a little before he lands. The timing of the action should be well grasped (this is based on experience) and the range of action should be appropriate. If the amplitude is small, there is no movement; A wide range will affect the frequency and accuracy of your shooting. Take advantage of the weakness of AWP's long shot interval, shoot as much as possible in the effective time, and you will get more chances to shoot with a small movement (only when you don't move your feet at the moment of shooting, can the accuracy be high).

It is very skillful to deal with dodge in a small map. Usually you won't be far away from the enemy in a small map, and it is very important to make good use of the wall in the small map, so that you can shoot ahead of time (listen to footsteps, listen to gunshots, judge the opponent's flash frequency according to experience, and so on). ), this will make your opponent feel that he is bleeding when he doesn't see anyone, or he will be beaten when he appears (maybe he will think you cheated, but he didn't).

The World of Snow and Ice is a good example. As long as they are armed with big guns, they can stand at the position where guns 4 1, 42, 43 and 44 are located at the beginning of each game (probably in the middle of the position, so as not to be seen by the enemy), lean against the inclined wall and press the gun to shoot 30 bullets. You are likely to kill enemies who want to pick AWP or 43 and AK guns. Give it a try!
