It took a while, but it seems to work now.syzygy wrote: ↑Sun Sep 29, 2024 6:56 pm Unfortunately, simply changing DRAW_RULE in the generator from (2 * 50) to (2 * 70) does not work.
The problem is that the values stored in the table no longer fit in a byte, so a "reduction" step has to be done before the "N-move rule" is reached. Not a major problem but it needs some work.
The only cursed positions with 5 pieces or less are in KQBvKB (using a 70-move rule).
And this still seems to be the longest win (DTZ=766 ply):
