On a standard board Black would have made an even number of moves; not so here, with Ra8-h8-b8-a8 (2020-10-05)
A.Buchanan: This has exactly 200 solutions as a PG in 8.5, for example 1.d4 Sf6 2.Sd2 Sd5 3.e3 Sc3 4.Ba6 Sxd1 5.Sf1 Sc3 6.Bd2 Se4 7.O-O-O Sf6 8.Kb1 Sg8 9.Be1. It's restored to soundness if "genau" is stuck in the stipulation. (2021-06-10)
