Counter Strike Tips, Use hud_fastswitch

Enable hud_fastswitch in your client. This will allow you to select weapons without having to hit the trigger in order to select them. Every second counts; having to hit the weapons category key and then the left mouse button takes time, and sometimes it's time that you don't have. Note that hud_fastswitch won't help when you have multiple types of grenades; in those cases you'll have to select the type you want and then hit the trigger to select it. But for all other weapon categories primary, secondary, knife, and bomb (for the Terrorists in a bomb/defuse map) -- this will allow an instance switch. Sometimes a single keystroke or mouse click can mean the difference between life and death.

When climbing ladders, do so quietly

Normally, when climbing (or descending) ladders, a fair amount of distinctive noise is made; if you're using this to gain access to an enemy-controlled location, this sound can give you away. You can substantially reduce this noise by holding down the crouch key while moving up or down; this reduces the amount of noise that you make to about half: It's still audible, but it's far less noticeable than the normal volume. Particularly if there is background noise, such as gunfire -- hopefully provided by your teammates -- this can make a stealthy incursion much more possible. Another little-known tweak is that you can turn sideways on the ladder (so you're facing the side) and use the strafe keys to get some added speed when moving on the ladder. For instance, get on the top of the ladder, face off to the left, and then hold down the backward, strafe left, and crouch modifiers; this increases your movement speed substantially without making more noise. Crouch while climbing or descending a ladder; you'll make much less noise.
