So the team does a 3 B/ 1short /1 long split with two of the three going lower tunnels to mid
You pop flash mid doors to your teammate then smoke off ct which by that your short comes and hold ct spawn so no one pushes through the smoke and the guy in long rotates to top of mid to stop the lurker
Then the 1 guy in tunnels and the 2 in middle flash all 3 entries (b door/tunnel entrance/window) and clean the site easily
