These are strats I have been using my entire career, from CAL-o to CAL-i. Most efficiently used by team Confederacy in our 19-1 CAL-Premier Championship season. If you'd like to download some demos to see these strats in action, check out Team Confederacy's website at www.clan-confed.com. It's important to do this to help understand the timing of the strats, as most of them are grabbing your attention in one area so players can surprise them in another area.

Note: It is very important to download the strat file and view the demos along with reading this article. These strats will mean nothing to you without it.

Pistol Strat (Rush Middle)
The Strat: This strat is very simple to execute, but not so easy to pull off. You're going to send all 5 of your players together up middle, into the Counter-Terrorist connector. Use jumping glocks to take over their usp's and go back halls back around to A.
The Reason it works: The reasoning behind this strat is that the timing catches the CT's on rotation in the connector, normally with flashes & nades out. Your jumping glocks will out number their single shot usp's, allowing you to take over the point. Once you have the connector, the rest of the round is a breeze, with easy entrance to the back hall and planting the bomb in A. It will be nearly impossible for a CT retake.
