Hi Allen, The annotate function in SCID is pretty basic. Yes, it will annotate a complete game for you but can't or doesn't do the following (all can be done with the Crafty annotate command) a) Set a threshold for determining when the moved played is not as good as the engine selected move. b) Analyze multiple games by player name rather than white or black. c) Display the score for the move played when the engine selected move is deemed better than the move played. I think the problem is more with the engine rather than the SCID interface. I don't know if all engines return to the calling program the same information or at least a consistent set of return values. The engine would have to return: 1) the score for the move played 2) the variation for that score (optionally used by calling program) 3) the score for the engine selected move 4) the variation for the engine selected move. Scores should be absolute meaning (+) indicates white's favor and (-) indicates black's favor rather than (+) indicating a score favorable to the side on move and (-) indicating a score not favorable to the side on move. If you compare the output of the crafty annotate command to the output of the SCID annotate utility, just the differences I have mentioned make the Crafty output much more informative than the SCID output. I'm not bashing Shane here. As a matter of fact, I am an advocate of what he has done and consider SCID an excellent Chess database utility with a very robust feature set. But right now, I annotate my games with Crafty and then replace the game in SCID with the "can" file. Steve
