Shredder Classic is a great tool for finding and saving reciprocal zugzwangs. However one has to be aware of a limitation : it will save only 3000 positions max. This is a problem for RN-BN (w draws - black loses) which has 7099 different positions !! (56792 with the symetrical ones). Same problem for RPP-R (3346 positions). The workaround is to have the white king "fixed" successively on 8 (EG without pawns) or 32 (EG with pawns) squares and add up the position sets. Not very convenient. Has someone a better idea ?
