Perhaps that means you need to find a new place to start Akule. For one, with the M4, the gun is so easily controlled (you can make 1 shot bursts easily), just aim for the head and plug the guy.
Try the crotch with the AK like I said earlier. With any of the subs, just spray, no need for bursts unless you are just trying to slow them down. I don't mean spray aimlessly, aim for the head. Those little things recoil can almost go un-noticed.
With the AWP, aim anywhere except for the arms and legs. Just remember, fire and run like a crack dealer in blue lights. With the scout, (god I hate this gun...) ALWAYS try and get the head...cause it's not NEARLY as strong as the awp and can have you sitting there frozen.
With the shotgun...jump boom jump boom. This not only makes you harder to hit, but gives you leverage so that you can get an easy head shot. Most people get antsy if you rush them...so that's about the best strategy with the shotgun...unless its the autoshotty (n00b t00b)...in that case just start blasting and wait for people to call you an idiot for using the gay gun.
Aug and SG, zoom and fire one shot bursts same as the M4. Only dissadvantage with this one is that it doesn't hit as hard...and just that one shot can make your gun go nuts if you don't have your sensitivity up high enough to control it.
BTW guys...I play 1.5 mostly...even though I do play a little 1.6..but these strats are my 1.5 strats so if anything is a little off...feel free to laugh at me
