codes at the console to activate the desired cheat:

To get 16000$ which is the max, sv_cheats must be on.

This will enable the cheats. After activating you must restart the level/map. 
Then type in impuse 101 in your console and you will have 16000 dollars! 

The other code is for the weapons. I dont want to take all the time to explain all 
the weapon names because if you already play Counter-Strike alot you should 
know the weapons/weapon code names. to get the weapons you must have the 
cheats activated once again sv_cheats 1. 

Now type the following in your console

 Purchase a smoke grenade: 
 Tago King, Submitted the following Information:
 Select or hold the smoke grenade. Find another player
 (Preferably a team mate or if you are courageous enough 
 you can target an opponent) Position yourself so that 
 when he runs you are at the opposite direction running 
 towards him. When the two of you collide, you will stop 
 moving. At that precise moment throw the smoke grenade 
 against him(between his face and torso)if you did it right 
 the smoke grenade won't bounce off as usual, instead it 
 will stick to him like glue. The target won't be able to 
 move for some time until the smoke grenade loses its 
 function and disappears. If you experienced being stuck 
 by this trick try jumping continuously and shoot the smoke 
 grenade by your gun or keep slashing it with your knife to 
 set yourself free.
 
 Purchase a flash bang: 
 Tago King, Submitted the following Information:
 Select or hold the flash bang then go to a corner wall. 
 Push or walk against that corner until u can't go further 
 then throw the Flash bang grenade. The Flash bang grenade 
 won't bounce off, instead, the wall would magically absorb 
 the grenade. As the Flash bang explodes, the blindling light 
 would affect anyone within 20-30 meters as if blinded point 
 blank from the flash bang explosion. No need to throw at
