Nah the reason is that you want to establish map control beforehand , control that you forfeit only when deciding to attack a site . For example , lets say you have a set execute for cache A . The place where you throw the smokes is really exposed to a garagesqueaky information push of a CT . You can ' t just go straight into a set piece because you don ' t have your fate in your own hands . All you do is hope no one comes when you ' re 5 dudes with smokes in hand looking in the sky . What you want to do instead is show presence almost everywhere . Even just going in squeaky , popflash in the corridor and spam 5 bullets in the door randomly is enough . You want to get map control for 2 reasons . First you deter aggression from CT for a bit no one goes aggressive if presence was shown 5 secs earlier and also to have some leeway in terms of space before the CT come into contact with you should they push right after you pressured . I mean you can patiently wait one minute not doing anything before executing , but you ' re just hoping they don ' t push right when you stop holding . You need to be proactive in establishing map control and dominance . The difference between average and great teams in CS is not allowing opponents some windows of opportunity , because as you play vs better opponents , they will seize everything they can . If your play is not solid and polished , you will be capitalized on . Establishing map control is a mandatory first step before executing , and that ' s why team take some time . Overpass is known for late executes because the areas to clear to push CTs back to bombsites are big and numerous restrooms , connector , construction etc . compared to something like D 2 where it ' d be only long pit and short .
