CBS strategy hotel (versus,infected)

What do you think of this strategy....?
In this case it is required a charger, a boomer and a smoker hence the name CBS
In dead center hotel where the door that blocks your path with fire should be a boomer, where surivors, either unfortunate or inexperienced shoot the boomer (bile not necessary) next to the fiery path block blows up the door unleashing fire. Before the survivors change course, in the staircase there should be a charger coming from behind charging one survivor to the end of the room. Since the charger can be shot and is on fire a smoker should spawn near the soon to die, pummeling charger so that the smoker reels in the survivor so said survivor cant be freed.
Guaranteeing one survivor kill that could determine the outcome
