In my opinion cheating. Wallhack.

Watch the train-demo -> 1:45 - 1:10
Very interesting: 1:20 - 1:15... He picks his knife, without seeing his enemy...

Banned him for one day.

Nothing wrong I think...

Watch the demo attentively at 1:45 - 1:10. First he looks for the guy on the ladder already at the stairs. Secondly he picks his knife a short moment before he actually see him.

This player looks clear to me. With headphones, enough UrT experience and knowledge of the map you can predict a lot of enemies without seeing them...

2:32: He corrects his aim, although with WH he should have known where this player appears. Could be done to "hide" his WH, but on the other hand this is no evidence of WH at all.
2:06: With WH he would have seen the player through the wall and predict when he appears. But he shoots too late, like he was surprised by the time of the appearance.
Guy at ladder: For me just coincidence, that his aim points for a moment (1:45) in this direction. A second ater, you can clearly hear the ladder sounds.
Knife scene: When he comes down the stairs (1:30) and turns right he sees the back of an enemy. He follows this enemy, and when you combine the hit/kill/death-message in the topleft (yes, I do this sometimes) with the shooting sounds, it's very likely that the blue player ist still alive and that he has a good chance to stab him.

So for me he is clear. It's always hard to proove a good wallhack and tell it apart from luck or intuition. Anyway, thanks for spectating and keeping the server clean!
