Henrik Juel: C+ by Jacobi 0.7.2 (29 sec.)
In Heuristic mode the solution was found in 1 sec. (2020-03-25)
Mario Richter: The solving speed is not so surprising if one takes into account that because of the "Bichrome Chess" condition all of White's moves are completely determined and that Black has to capture white pawn d2 and wSb1 on their home squares. (2020-03-26)
