This strategy is what my premade does almost every round.
Requirements: 2 Smokes
Plan: 3-4 players will go mid, the best aimer will go B apps. The mid players will smoke window and connector, then rush short onto B. The apps player is to make the entry kill and alert the team if theres a CT near short. Typically the B player will hold bench or van. The other will be kitchen, short or under the appartment window. Simply there job is to make the mid players have an easy access to get onto the site. Once the site is taken a awper/rifler must go to van to shoot any CTs that cross through market( kitchen ). The rest is up to the players.
