I am trying to learn Portal 2 speedrunning. Can you help me with some of the basics, such as bhopping?
Sure, I can help you with that!

Bhopping, or bunny hopping, is a technique in Portal 2 speedrunning where you jump repeatedly in order to maintain momentum and move faster. Here are some basic steps to follow:

1. Begin by moving forward and jumping. As you land, jump again immediately.
2. As you jump, strafe to one side using the A or D key on your keyboard. This will help you maintain your speed.
3. As soon as you land, jump again and strafe to the other side using the opposite key.
4. Repeat this pattern, jumping and strafing back and forth, to maintain your speed.

It can take some practice to get the timing right, but once you master the technique, it can be very useful for quickly moving through levels in Portal 2.

Here are a few additional tips for successful bhopping:

- Try to time your jumps so that you land just as your previous jump ends. This will help you maintain your speed and avoid losing momentum.
- Use your mouse to adjust your view as you jump, so that you can see where you're going and avoid obstacles.
- Be careful not to jump too often or you may lose control of your character and slow down.
- Practice on different surfaces, as some surfaces may be easier to bhop on than others.

Good luck with your speedrunning!
I cannot, sadly.
