You can use this useful guide for any competetive or casual game of counter strike.
If you have enough ammo and patient teammates who won't kill you you might profit from this but the chances are pretty low.

OK so I will just put here some pictures that will pretty much explain it itself.

1. When you get out of spawn you will see these bricks, few of them have physics so you can move with them. Choose one and start shooting it the right way.


Yup get in lobby with that brick (don't forget not to get killed).

2. See these doors? You'll have to destroy them. So just get back on spawn, buy a grenade and nade those doors.

Like this!

3. Shoot your brick on A-plant

4. When you finally get your brick on the right spot just take your C4 and plant it in the middle of the brick.

Like this!

PROFIT!!!!!

...enemies will have no idea where to look becouse that brick is basically invisible for CTs (from some reason)
