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."

Can anyone knowledgeable in Chess game engine explain how this app is different from other engines out there?
I would expect that the branching research factor is proportional to the small cellphone CPU, so this won't compete against deep blue class setups.
So how does it evaluate the best move? Correlation and statistics from all the games stored?

It seems to be based on HIS OWN game history, rather than actual logic.
As best As I can figure it, it looks up boards with the identical deployment (or as close as he can come to it) from his history, and makes the move he made next.
But precisely who is "that anal" that they recorded every board they played back to an age of 11? Or maybe he just has an eidetic memory.
No, you are mistaken. I've always had this sig.

He does have an excellent memory. Every great chess player has a freakish ability to remember chess games, not only their own but ones that have studied of other players. If the game was played in a rated tournament, which Magnus has played a lot of, then it is required to keep a score sheet and write down all the moves. The exception to this is blitz and rapid games where there is not enough time to record the moves. Today modern master level tournament and match games are recorded electronically on digital boards [chesscentral.com]. There's also the thousands of games he's played on-line that are archived out there on places like ICC.

Ok, so Bobby Fischer was something of a bad boy, but does that mean the International Criminal Court has to track all these buys? ;-)

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.

Play the Grob like Nakamura [chessgames.com] and maybe win in 255 moves!
Unfortunately it's difficult to get a psychological advantage over an iPhone with an offbeat opening.
