E.g., on move 1, f8=Q works just fine, but isn't allowed; only =R is acceptable. After 1. f8=Q...g×f6, 2. Bg8...f5, 3. Qc8...f6, 4. Qc4#. There's no need for 3. Q×f5 = ½ (which 1. f8=R prevents). I know two decent chess players who eschew gameknot because of this defect. There could be thousands out there.

...how many "fails" were good solutions, but the biased move list called effective moves "Incorrect" or "Wrong move?"

E.g., on move 1, f8=Q works just fine, but isn't allowed; only =R is acceptable.
After 1. f8=Q...g×f6, 2. Bg8...f5, 3. Qc8...f6, 4. Qc4#.
There's no need for 3. Q×f5 = ½ (which 1. f8=R prevents).

Sorry 😐
