1. Do not switch your guns unnecessarily. It does not makes you
look like a pro but instead makes you look more like a farktard
when getting owned.
2.Many people have the inclination to reload their bullets when it
isn't very empty ? By this I meant guns with 20+ bullets. Many
people have this bad habit [ Like me ] so try your best to stop
reloading.
3.Before you throw your precious flashbang lookout to see if there
are any teammates around. I realized on server a Hongkong farktard
deliberately throw at teammates..
4.Try not to block your AWPing teammates and it could annoy
them.
5.Footsteps. You can listen to footstep e.g. tunnel in de_dust2 and
it may earn you some extra
frags
6.Some people has a unique way of shooting, that is after they open
fire they use DUCK key to squat. I am one of them, but this results
in low accuracy,unless you are talking about targeting their head,
open fire and squad..
7.For AK you could consider this - Far range use a bullet at a
time, don't hold but pressing repeadly. This is very accurate as
every bullet hits. For close range you can use 2shot per click. For
Very near range do your best to spray !
8.Locating your crosshair above chest level helps better for
headshot.
9.Solitude kills. What if the other party whole gang chiong same
place? Good luck then.. This type of scenerio often happens.
10.Signals. When your teammate use C2 enermy spotted or c3 Need
backup you locate where he is from radar and sapport him, or else
inevitably you are the one losing out.
11.Many people do not use radar. Please make it a point to check
radar often like you go dentist every 6 months ! I am not
suggesting you check your radar every 6 months but try to look at
it when your teammates die
AWP Usage
AWP is suppose to be one of the most powerful weapon in game
alongside AK47 and M4A1 Karbine. If you use it wisely you might own
the whole game.
1- Dragshot. It means when the target is moving you drag your mouse
along where he is going but aim your crosshair at spot before he
reaches it.
2-Blindshot. Without training all I can say is work hard..you are
not gonna hit any target near range..
Let us identify 3 types of Sniper in game.
1st type - Runs to a spot at start of game and camp. - No real use
as he just waits without give sapport to others .
2nd type - Go along with team sapporting them behind. - This kind
of ally is good ,give support to team
3rd type - AWPer rushes infront of team and pwn the other team
..
- If you are really pro or cheating I suggest you don't do this ..
you might get killed
BTW mostly all of above ideas I get from a chinese website

I appreciate any feedback and suggestions .. if you think I am bad
you can go ahead and flame me ..
