So i was practicing doorlaunch and happened to end up abhafh-ing standing up. i got a little spastic with my ctrl button, and was using sv\_autojump 1. I dont record demos of me practicing so i was just curious if anyone else has had that happen? it was the weirdest thing visually. it was like i was standing, but abh-ing. Also, I assure you I am quantum crouched. If you load the save and experament with it you can see for yourself. UPDATE: I GOT A SAVE OF IT. WILL UPLOAD DEMO SHORTLY Cannot get it to record and work at the same time. will upload save. [LINK](https://www.dropbox.com/s/3b6bgpe7xly4h3d/qafh.rar?dl=0) to help you get it working, when you load it just hold ctrl, s, and mash jump (before it finishes loading. i recommend using sv\_autojump or a macro or something). you may want to bump left as i was curving to the right when it happened. other then that, see if anyone can recreate it. ---

You don’t need to be crouched to ABH/AFH. It still works, you just get less of a boost (but jump higher). You need to crouch at the start of ABH because you need to be going faster than a certain amount times your walking velocity, and crouching reduces your walking velocity. It’s the same reason you can do a standing ABH if you sprint in HL2. ---

It’s the same reason you can do a standing ABH if you sprint in HL2. I promise, I’m quantum crouched. I hit the ledge in section 3 and saw outside. Also, if you stop jumping you can tell it’s quantum crouched. Not sure how I did it. But I did. ---

You’re doing a quick quantum crouch, that was used in PDI and even in por, basically if you crouch while going through a portal with the right timing, you end up in a quantum crouch state where you can jump, and if you have enough speed, you can abh or afh. ---

Yeah this is pretty easy to do accidentally in 10, nothing new I’m afraid. ---

It was even done in PDUF in 15 I believe. The trick itself is pretty old and as Jukspa said it’s very easy to accidentally do in 10. ---

Well damn.
