This has probably been thought of several times, but here goes anyway.

I enjoy playing a computer when it plays more like a human than a computer. It
seems to me that we are not quite at the point (yet) to make a computer play
like the best players in the world (while we can make them play at their level,
we can't make a computer "think" like they do). Programs like Chessmaster 9000
attempt to do this with personalities but only in trying to "guess" what the
player would choose based on material and positional ideas, not actual data.

So why hasn't there been a program which can load up a set of PGN files (played
by a human opponent) and then create a learning database off of them? Like if I
download all of David Janowski's games, have a program analyze all of the games
and create a player (perhaps within 90-99% accuracy) which plays and thinks like
Janowki did.

I wouldn't care if it took the program 2 days to analyze all of the games
carefully before the personality could be created, at least could it be
possible? Maybe a program can already have a few pre-stored?

I'm not just talking about simply "playing" what Janowski plays at a certain
position, but rather playing "what he could" play based on this data and his
philosophy looking at certain positions. Sort of like "The Sims" meets
"Shredder". :-)
