andrew writes "Magnus Carlsen, arguably the best chess player ever, has made a new chess app available on iTunes. PlayMagnus claims to be able to mimic the play of Magnus at different ages from age 5 to his current world championship strength at 23 years old. This is made possible by use of a customized chess engine built on thousands of different positions from his games.

From Reuters article:

So what is it like for Carlsen to play against his younger self?

"He is really tricky," the champion said. "Even Magnus at 11 years old was a very gifted tactician. A while ago I played as a test Magnus (aged) 14. I outplayed him at some point positionally. And just boom, boom, he tricked me tactically.

"But he makes mistakes as well, so I just have to be patient."

Magnus also plans to eventually add the functionality of on-line chess games against other app users, a service as old as the Internet, putting his app in direct competition with long established chess servers like FICS and ICC."

    There are 7^64 possible chess positions, with the number of possible moves increasing at a rapid rate from the first move on. While his professional games will have recorded thousands of common, perhaps hundreds of uncommon, and a small handful of unlikely positions and his subsequent reaction to them for each year of his career, you are still playing a deterministic chess algorithm and not a true representation of a game with the champion. You might be getting a move he made in frustration or when he had a cold, and you will most certainly not provoke a frustrated move.

    I can only consider this selling based on brand recognition rather than some novel new approach to a chess game.

    There aren't. For starters there are black and white pieces, which makes the naive figure 13^64. Then there can only ever be exactly one black king and one white king, a player's pawns can never be on his back row, and (pawns+promoted pieces)=8, and so on. A lot of double checkmates are ruled out, 10 bishops of one colour can never all be on the same colour square, etc, etc.

    Whether or not that works out to more than 7^64 is left as an exercise for the reader.
