Go up one level in this thread
Pawnless files withe equal material ("symmetric") are absolutely identical. I
ignored that fact when the only such files were KNKN, KBKB, KRKR, and KQKQ, as
total saving were ~6Mb, and I decided not to complicate the program. But with 6
man TBs saving is much more, so I modified the code. Now for pawnless symmetric
TB only WTM file is necessary.
For TB with pawns situation is more complicated: it's necessary to "flip" the
board for BTM. I had not done it yet, and I think that we have more than enough
time before that issue will become actual.
