Hello Arturo, I am probably risking a royal roasting but I am going to suggest that perhaps there is a misunderstanding here. I do not believe he is even hinting that the book used was a book built by Chessbase (say the generic book that ships with several programs). There did not seem to be an attack on the integrity of Anthony Cozzie, Erdogan or yourself. I think what Uri is talking about is the actual mechanics of how the moves are chosen by the Chessbase gui. There are guis that enable engines to use tablebases. What actually happens is that the program (chessbase) recognises that a position on the board consists of five pieces and searches the appropriate file. This is different from guis such as Winboard or Arena where the engine itself has to be able to use the tablebases or its no go. The King serves as an example. In the Chessbase gui if you put the white king and two bishops in one corner and the sole black king in the other, in the Chessbase gui with egtb's enabled the "King" will spit out mate scores (mate in less than 20 incidentally) whereas in Winboard black will show a negative score of 8.88 (I use an adapter to decimalise the King's output) but no mate scores. I put the King in quotes because the King can only use its special tablebases and only in its native gui so it is clear that the chessbase gui is "assisting" the engine in that it is not the engine which is searching the egtb's but the gui. There are uci engines that use their own books in the chessbase gui. Zappa does. The native format means that the gui is handling the opening book moves, not the engine. I believe this is Uri's point. Now I may be wrong and if I am there are sufficient experts here to correct me I am sure. I would just like if the discussion could move to the technical away from the personal. I hope this is not a case of writing craps... Later. Ps. Congrats on Zappa. To think that I have a version of that engine as freeware. This is a *polite* question: I see your rather sombre photo as being involved in the opening theory support of a rather intriguing three d program which is coming soon. How is that progressing? Thanks for reading this...... :-)
