There really aren't any cheat codes for CS, unless you are talking about server based cvars.
People don't hack/cheat on secure online servers, because if they are caught, they will receive a VAC Ban. They will no longer be able to play any games on Steam.
If you own the server or have administrative rights such as "rcon" you may use the following cvars: sv_gravity, noclip, impulse101, sv_cheats
They are not considered cheats, because they were already built into the HL engine.
sv_gravity_70
There are no official cheats unless you are admin of the server.
Play legit.
