Was trying out a chess game I downloaded yesterday. It called Pawn and it's totally free (freeware).
It is really user friendly. And for those who like to cheat, you can choose the special beginner's mode, which lets the program make mistakes, thus enabling you to win. You can even go back and save the game.
I tried the intermediate mode (didn't cheat). Played a few games and only won once against my computer. I was tired OK!
Unfortunately this game does not have any support. So if you have problems (I doubt it), you are on your own.
