re: Quick tips for starting out on CS:GO?

If you're using an AK for example, you'll have different ways you should fire based on how far the target is away. Ak is generally 2 shot burst at long distance. The first shot from an AK is dead center so long as you're not moving.

If you get in a firefight with someone, never stay still for too long, it should be short burst, move, short burst, move. Crouching improves your accuracy and has its appropriate uses, but noobs tend to overuse crouch. I would tell you not to use it at all.
