To install the map, you only need to unzip the folder where you have maps installed the game, in my case is:

C: \ Program Files \ Steam \ SteamApps \ STEAM_ID \ counter-strike source \ cstrike \ maps

Once unzipped to play with bots must enter the game and put only 1 bot, wait until the bar is full and add more bots. (this only needs to be done the first time).
