i use zoom_sensitivity_ratio 2for awping (most people suggest only as high as 1.2 as it is a large difference compared to using m4\ak), it means that the sensitivity when you scope doubles (i.e. i use sensitivity of .8-1.3 with dpi of about 1200-1600, using this it puts sensitivity up to 1.6-2.6) now i only started using this recently and i found an immediate increase in my kills. the only thing is u need a steady hand and quick reflexes.

To increase ur chance of a hit u use a quick slide of ur mouse over the player quickly (1 side to the other), at which point u fire. this increases the size of the hitbox and works well on 66 tic servers as the hitbox is larger as it doesnt update as much as 100 tic.

After u shoot u should have ur keyboard set to have q as like a quickswitch, press qq really quick, scope then fire again. this gives a fraction faster fire rate with the awp and it seperates nubs from pros.

Ill add to this over time and if i get fraps, gamecam or if i figure how to convert css movies to compatible files for youtube ill add a video tutorial to reinstate what i mean
