Line your self with the pole, aim at the brown stain on the wall and Jumpthrow.
NOTE! that in the video and the line up picture its 128 tick so aim at top of the brown area in 64 tick servers.

This line up is originally from other video: https://youtu.be/1XQQhDnhMnQ
This is just cleaner version of that.

Hope you enjoy it :)
