All of these are analyzed by the [truly excellent] program 'Chest' by Heiner Marxen (and others). >How did you select what was mate positions? I don't I just give all 10,000 unique rows to Chest and let it fly. Some of the positions are already mates. Chest looks for a shorter one or validates it (sometimes, the mates are wrong). Some of the positions are not known to be mates. Chest searches 10 ply exhaustively for checkmates. Some have been found this way that were not previously known. A deeper search will find more (I am sure).
