Hi,

Where can I find a list of 4- and 5-piece positions with maximal DTC, and the same for maximal DTZ? The list must show for each possible 4- and 5-piece combination (for example KRKB, KBBKN, KQPKQ, ...) not only the maximal DTC and/or DTZ, but also a specific position. For example, for KBBKN the list should give a position where capturing the knight actually takes 66 moves.
What I need most are the following:
KBBKN, KQRKQ, KQKBB - positions for maximal DTC (or DTZ - there is no difference);
KNNKP, KQPKQ, KRPKB, KQKRP - positions for maximal DTZ.

Thanks.

Please find attached the package of information I got from Christoph Wirth in about 1999. Note that Christoph's depths are in plies.
I think there was an issue with Christoph's depths in that he assumed that the loser is never forced to capture, so the depths are '1 ply out' in these situations.
DTZ == DTZ for P-less endgames. For P-ful endgames, DTZ EGTs have been calculated for 3-5-man endgames, and the statistics are available at http://www.icga.org ... Game-specific infor ... W Chess ... Endgames.
The maxDTZ sets of positions have not yet been computed for P-ful endgames.

Thank you very much
