Chess theory. Sometimes the C.A.P. data suggests a move that is known to be inferior, especially in the opening section of games. >And what is the >current theory? Good question. I hope that owners of the most recent ECO and related volumes can look it up. >One thing that makes it difficult to compare the two sets is that the formatting >of the output is so different.

The first letter of a move is the piece, then the source square, then the target square. >Also, it has no given search depth >and is missing any other indicator of how deeply it was searched. It was searched much more deeply than a PC can hope even to imagine. >One other question I have is what program(s) the new data came from?

There are both higher and lower evals. >Is this just some subset of the total positions >where this occurs, or is this indicative of the entire set? It appears to me (at first blush) that the supercomputer evals are better. >Sorry for all the questions. :) Hopefully you can provide me with some >enlightenment. :)
