As we all know , most starters are playing Dust 2 ( competitive )

Usually , me and my palls are playing 3 A , 1 Mid and 1 B.

To hold B :

1. Before you enter B ,when you are outside the doors throw a Smoke on tunnels ( this will stop the enemies rushing )
2. Instantly throw molotov in front of the smoke ( this will damage enemies even if they decide to rush thru the smoke )
3. Hold tunnels , everyone who rushed is now on low HP

Tip : Sometimes they hear the molotov and throws a smoke to it , i suggest throw a nade too.
