1. Smoke for entrance from outside
2. Hut molotov
The fire completely covers the hut's roof and successfully smokes out players sitting there. It's better to break the glass on the roof for this; otherwise the nade can blow up on the way and not set the roof on fire.
3. Heaven smoke
There are a few variants of throwing a smoke to Heaven, and some of them can be done only if the roof's windows aren't broken. Thus, the CT players often break the windows at the beginning of the round, but this smoke bypasses this trick without difficulty.
4. Heaven molotov
If your smokes on Heaven are gone already or if you haven't thrown them there at all — the fire thrown from the door may come in handy. Combined with the smoke thrown to the entrance, this molotov allows to force out players sitting on Heaven almost without any risk.
5. One-side smoke on Secret
We've got only one trick for the CT players today, but look how good it is! This one-side smoke to Secret allows controlling the outside and remain unnoticed by players taking the outside.
Bonus: magic graffiti
The graffiti have a magic effect — they are transparent only from one side, and that can be used in your favor. For example, you can spray graffiti on one side of the glass surface and thus hide yourself. It's noteworthy that the graffiti doesn't disappear when a next round starts, indeed, you can ask your teammates to help you spray a few additional graffiti, too.
