Advanced Techniques and Tips
1A.When rushing in a public server, learn the spawns. Learn the routes, and learn the maps. If you want to rush long A on dust 2, but you get a spawn in the back corner... don't try to rush long A anymore. You will be too late to the chase because other CTs or Ts with better spawns will beat you there.
2A.When using the desert eagle, people tend to spam fire the weapon. You have 7 shots only and if you spam them all, you will be lucky to land 3. (the usual amount of body shots it takes to get 1 kill, 1 shot to the head will put someone down instantly, however) Wait about half a second longer and even when running the desert eagle will be very accurate. It will feel like you are going to get less kills, but in reality you will land 3 shots faster with good aim and pausing longer then you would to spam with good aim.
3A. Very Advanced TechniqueWhen trying to assault an awp user, at any real range it is extremely difficult to avoid death. The best tactics to use are to pop around the corner for a half second or less, and pop back. As soon as you hear the awp'er miss the shot, sprint around the corner and try to get a shot off on the head as fast as possible. This takes hard practice and work, but once perfected you will be a force to be reckoned with. Smoke grenades are the best cover system in the game. They don't block bullets, but they are portable. Learn to smoke out common awp spots to avoid getting picked at the same place every time. And lastly, flash grenades blind people. We all know this. But if you blind the awp'er you can easily over take him with 2 or more people, and by yourself with practice. The awp'er will either return to his post after he is no longer flashed if it sounds quiet, or if your making lots of noise (running basically, shooting as well) he will take up the next closest awp post that will result in your death. Learn all the common spots on the map and bring plenty of flash grenades and smoke grenades.
4A.When planting the bomb, plant for a spot that you can easily defend. A great example of this is planting the bomb at the corner of A on dust 2, and then awping defusers from the snake pit.
4B.When defending the bomb, if you cannot awp or snipe from a distance, find a corner or a hidden spot near the bomb. Listen for the defuse sound, assume the defuser has a kit, and use the 3 second rule. If you do not hear another defuse sound after 3 seconds (count a tiny bit fast for insurance) then assume the defuser is going all the way with the defuse. If you do hear another sound then start the 3 second count all over again. Once you don't hear the defuse sound after 3 seconds, pop out for the kill, or throw a flash grenade. The defuser will be blind for the kill, or will force the person to miss the defuse allowing the bomb to explode depending how much time is remaining on the timer. Optionally, throwing the flash at the head of the target will interrupt the defuse.
