伪高速飞行
伪高速飞行（英语：Pseudofly，简称伪速飞）是一项锤击飞行中的进阶技巧。伪高速飞行与高速飞行的相同点在于两名玩家在飞行过程中不会发生碰撞；而不同点在于，伪高速飞行可以在空中更加灵活及精确地移动。
熟练掌握伪高速飞行后，玩家可以用这项技巧来与其他玩家或与自己的分身随意地向着几乎任何方向飞行。
通常来说，玩家与自己的分身进行配合会更容易完成伪高速飞行，当然也可以双人配合完成伪高速飞行，但是需要两名玩家要有极大的默契程度。
钩索释放时机
伪高速飞行与其他锤击飞行技巧相比，最明显且重要的区别在于钩索的释放时机。
与常规的“两锤一钩”不同，在伪高速飞行中，驾驶员必须在每一次锤击时重新释放一次钩索，也就是“一锤一钩”。
同时，驾驶员也要格外注意钩索释放的时长。驾驶员要将钩索释放时长把握在驾驶员与动力源之间的距离刚好在锤击判定范围之内，而两者又不发生碰撞的距离。
- 如果钩索释放时长过短，那么可能导致两名玩家之间距离过大，动力源的下一次挥锤无法击中驾驶员；
- 如果钩索释放时长过长，那么两名玩家可能会发生碰撞，导致伪高速飞行中断，被迫切换为常规的锤击飞行。
因此，驾驶员需要集中注意力在两名玩家的距离上，以便随时判断下次锤击后需要释放钩索时长的长短。
当玩家已经适应并熟练掌握了钩索释放时机，那么接下来就可以尝试向各个方向进行伪高速飞行，甚至是悬停在半空中。
下降高度
When pseudoflying down, the driver must hook for shorter time lengths as well as more sparingly. Flying down is basically like falling - except occasionally, the driver hooks and the hammer tee hammers.
When leveling out again, simply increase the rate of hooking and hammering.
Transitioning into speedfly
To transition into speedfly, the driver must be especially careful about the hook timing. When you feel yourself starting to go up, the driver must hook for a little bit longer as speed increases. Once you go fast enough, the driver must hook for every two hammer hits instead of one, like a normal speedfly.
An alternative method to transition to speedfly is to have both tees hammer each other at the same time, and the driver to quickly move left or right, and then level out again. This is much faster method, although the same principles as above still apply.
Use cases
A common use case for pseudofly is to fly through tight horizontal corridors that would be unpractical, or impossible, for any other kind of fly.
Pseudofly is also a common technique used in speedrunning.
Starting a pseudofly
When pseudoflying with a dummy, it's important to control the rate at which the dummy hammers. Therefore, auto-hammer is not enough. You can bind a key to have your dummy hammer at will using the following command in the console (F1):
bind x "+toggle cl_dummy_hammer 1 0"
Once you have that set, you can start pseudoflying.
It is possible to start pseudofly in the air, but it is easiest on flat ground. Start by standing next to the tee, then have the dummy hammer you at a fast rate, hook him at the same time, and start moving in the opposite direction in which you are positioned from the dummy.

Starting pseudofly midair with dummy.
When pseudoflying with another player, it's important to communicate with them when it should begin. As the driver, you can do so by hammering, switching to the pistol, and shooting at a fast rate.
