I run a Linux box and do all my analysis in the background (nohup...&) and it is great. The following is a comparison of a couple of the features between Yace and Crafty. I use both Yace and Crafty for my analysis and compare the results of both. The analysis is mainly for OTB games I have played and an occasional game I play against a computer (not many). There are two things that Crafty does that Yace currently doesn't do and one thing that Yace does that Crafty does not. The two things Crafty does is: 1) it allows you to analyze games based on the player's name and not just b|w|a This allows me to send it a pgn with multiple games in it, supply my name, and the analysis is done from my point of view. 2) the scores are absolute and not relative meaning that plus(+) scores indicate white's favor and negative(-) scores indicate black's favor regardless of what side it is analyzing from. The one thing that Yace does is: 1) it gives a score for every move regardless of what side it is analyzing and only shows the variation for the requested side when that score is greater than the margin that is provided. Crafty only shows the variation and score for the requested side when the score is greater than the margin. If Crafty were to incorporate the Yace feature and Yace were to incorporate the Crafty features I would have the best of both worlds. By default, Crafty analyzes all games in a supplied pgn file and Yace annotates only the given game on the command line. I don't know which is better here. However, there are many times where I have a 5 or 7 game tournament pgn file and I want to analyze them all. With Yace, I create a command script having the game number and the side to analyze for each game. With Crafty, I supply it name of the pgn file and my name and away it goes. It would be nice if both added an argument for the game to analyze where zero(0) would mean do all games in the file and a number greater than zero would be only for that game in file. Regards. Steve
