Chessmaster Challenge

Long time no chess...Downloaded a Chessmaster Challenge demo just now from RealArcade, and beat an opponent rated at 532 in 7 minutes with the last check move of the Queen, my basic rating 300 jumped to 932 at once. But don't know how hard it might be when challenging the 2933 guy - so called "The Brain Behind the Finest Chess Programme in The World"...Urr...The art design of the game looks quite good with many nice chess boards to choose from, and the basic training, the chess coaching, and some puzzles seem to be well set up as well, it may be worth the money to buy its full version.
