Good player sadly appears to be using a toggled aimbot. Crosshair jitter, variable m_yaw speed and large over drags with perfect aim correction.
Demo:
http://www.mediafire.com/?c4pel4om3va9fx5Sorry it's a complicated demo, trying to watch several players at once can be frustrating. Had been called to server with reports of multiple cheats. Player "Huehuehuehuehuehuen" initially reviewed on arrival, strange play style and wierd target choices seen at timestamp 30:45 onwards. Burst fires at long A ramp when missing but one shots on kill. Interesting but was only one kill. On the followup when looking long completely ignores exposed and stationary ct in pit. Strange. Follow up at long corner shows his dragback spray to be quite accurate. Suspicions raised but nothing blatent.
At timestamp 32:45 variable m_yaw first noticed, large overdrag to the right of target with immediate pullback and equivalent over drag to the left followed by perfect centre chest shot with quick scope awp. Dies immediately after to common camper spot in goose overlooking long. Distracted for the next 2 rounds watching "I got big guns" who had been reported by players and seen to be wallscanning.
At timestamp 37:08 player "Huehuehuehuehuehuen" makes a nice deagle headshot, looks like a clean kill, notice the small movements of the mouse on the followup as the player tightens his grip on the mouse after. Then seconds later draws AWP and the crosshair jitters as he corners out from short. He only misses the shot because he's moving while firing with the awp, crosshair is firmly on center chest. During the follow up the crosshair yaw speed is much higher and he overdrags his target spectaclarly in both directions once again whilst correcting for the half bunny dodge, and yet again lands a centre chest shot with a quick scope. Again shows large overdrag at 37:35 when shooting at long pit, indicative of his high mouse sensitivity.
At 37:40 at long corner deagle flick shot with large over drag once more misses spectacularly, but then jitters and locks on after 3rd shot with the deagle. Classic tell-tale of particular custom cheats. While when using the AWP the difference in m_yaw speeds could just mean a player using a weird zoom_sensivity_ratio and high sensitivity but combined with the jitter and deagle lockon I felt the evidence was conclusive and banned. My apologies, you're clearly a skilled player but crosshair jitter like that means only one thing. Banned.
