Go up one level in this thread


Chess Assitant has the ability to build the first tree for 20 plies and the
second tree for 19 plies. Then it is possible to subtract the second tree from
the first and you will get the staticstics for every position after exactly 10
moves. But there is no output of the tree to a file. If this thread is alive I
can do this. It will take half of hour to build the trees, to subtract and write
the code that export the positions with number of games for it to a text file.
Then you need just sort the list.

There is also another utility (BookBld.exe) that generates all positions that
occured at least at specified number of games (doesn't metter on what move).
Some positions can be after move 1, another after move 25. This way positions
for CAP project were generated. First all positions that met at least in 50
games were calculated, than 10 and now all positions that were at least at 2
games are calculated.
