Well, this ain't Deep Ftriz 9 or Shredder 9 and I am sure there are 100s like this out there. But if you are in a hurry or need a break for 5 mins from working, you can play this and solve chess problems like mating in a given set of moves from game positions.

Daily Chess Problem is a fantastic initiative for those who would like to solve a problem or two getting away from the problems of everyday chores.
Mind you, it might get real addictive in a short time.
Don't believe me? Try it out here then.
