Yeah, there are various of different tactics out there, depending on the enemyteam and map.

At the end of the day, the most important thing is to win rounds (and have fun...) and that's often related to a good team with communication skills (typing, pinging, talking) and with good FPS game sense (even if you aren't familiar with the played map), with all that, including the knowledge of aiming and handling the recoil, you'll rank up, eventually!
