First clip: The first time I watched this, I only noticed the 1 enemy and didn't think much of it. When I watched it with a wallhack, a second player was clearly visible, and zoogooz reacted to that player, so I though "Whoa, you couldn't even see him before. That's pretty sketchy." I went back and watched it without a wallhack again, though, and noticed that the second player does actually come into view, and it isn't until that player comes into view that he reacts.
Bridge: I thought this was sketchy, even without a wallhack, but once it was put into video form and easier to analyze, I realized he wasn't really looking through the bridge, but rather positioning himself so that he could clearly see on either side of the bridge. He knew where the enemy was, because he could clearly see him before he went under the bridge. If the enemy moved in either direction, he would likely pop into view from the side of the bridge, since he didn't, zoogooz knew right where he was.
Stairs: I don't really see anything suspect about this one. The guy ran down the stairs and zoogooz shot him when he reached the bottom. It might have been questionable if he was shot before that, but I think there was plenty of reaction time available.
Last (I think?) clip: zoogooz fires at the opponent, then enters the bunker, after which, he turns toward the entrance of the bunker, when with a wallhack enabled, you can clearly see that the other player is still on the other side. After leaving the bunker, he sees the player go right and he goes left, I assume to try to intercept him, yet he still takes one quick look back to make sure his enemy didn't decide to change directions and try to shoot him in the back (the wallhack clearly shows that was not the case, so why look back?). This slowed him down a little, and when he reached the middle, he seems to have thought the enemy already crossed over to the other base and "chases after" him, even though he's still on that right path.
Good job on the video, btw, S8N. I think you made it as fair as possible.
