Most backstabs rely on targets being distracted with something else for successful execution. So long as the enemy is occupied, they won't have a chance to turn around and check for someone coming up behind them. Therefore, if you're  behind a friendly Spy who is moving in on distracted opponents for a backstab, hold you fire, and let him take them out.

If you attack that opponent from behind, or do anything else that would grab his attention, he'll turn his attention towards you, as well as the spy, blowing his cover, and ruining a clean kill. Don't try and attack at the last second so you can get assist points either, as you have no idea how fast that guy's reaction speed is, or if the back stab won't register. Either lay low, and let the spy take care of the enemy quickly, or create a distraction that will keep enemy fire off of the Spy.



Bonus Tip: Spies, don't spend forever setting up for a backstab. you should go for quick picks on high-priority targets and sapping buildings, instead of chasing one Pyro who doesn't even know where he is across half the map. A disguised Spy chasing someone for an extended period of time is easily identified and killed by the enemy team. If your target is out of stabbing range, and is at low heath, take them out with your revolver. Otherwise, break off and find something more worthwhile to do.

"Team Service Announcement" is a series where the common mistakes and unused strategies of new and inexperienced players are blown out of proportion and explained in an attempt to help those who make them, as well as make my life less horrible.

If you know someone who's new to the game, is in need of some pointers, or just want to spread the message, share the videos and help improve the community.

If you're a frustrated player who would like something addressed, or a new player who would like something explained, leave it in the comments section, and maybe I'll animate it.
