Keep crosshair slightly off target and always spray. No tapping. No bursts. Run and shoot if possible.

Never ever save. Do not coordinate with other peoples buys or saves.

Never buy a defuse kit.

On pistol rounds do not buy armor, buy a nade, and rush the enemy so you can drop an extra nade for them to use.

Do not call out anything. Dont even type or use your mic at all.

If you have excess money, wait till your team leaves spawn then buy extra guns and throw them away.

Put yourself in the middle of your team's rushes: if you're in the front, you become a shield for your other teammates, if you're in the back, your death will tip off your team to surprise flanks.

Try to die before other people. The less people spec'ing you, the more reckless you can play. This is also important to do when your team has a bot as you can now die two times per round!

And of course, do not use cover, Put yourself out in the open as much as possible.
