Positions 5 and 13 have illegal solution moves! May cast doubt on the integrity of the other solution moves especially without any confirming analysis.

One of the members there asked for the PGN file the positions were taken from .. I agree Skynet ..

5"/pos., 30 threads or 16x3.5GHz CPU, 3070ti GPU (for LC0) evaluated with EloStatTS (Frank Schubert).

Set1 means Iccf MultiPV Search = 2, Iccf Search Depth=19, Iccf Search Wide checked, Materialistic Evaluation Stratgey = -75, Positional Evaluation Strategy = 50.
MV4 now and then at other engines means MultiPV=4 (Fritz18 GUI).
