Thanks for your comments. I can understand the 8 major rotations being taken into consideration when developing egtb's but does it also take into account the following:?? NOTE: key piece is defined as that piece which is the piece that is to be moved according to the first egtb recommended move and all other pieces have a fixed position. Assume you have a board position with 3 pieces on it, say BK,WK and WR. And lets say for this particular position the solution for starting the mate sequence is WR on F3 to F8 according to the main egtb. Lets refer to F3 as the key piece and F8 as the target square and the kings are "fixed pieces". Now as long as the key piece can reach the target square doesn't that imply that as long as we find the key piece on either F3, F4, F5, F6 or F7, and the kings are in their same position, that the same key tablebase can be used or is this also done in the prior methods? Just looking to understand what actually has been done with the prior methods and maybe have to much free time <s>. Thanks, Les ps Ernst is your book hard or soft covered?
