A.Buchanan: The final move "Txg5#" was now correctly marked as an error, because it was ambiguous. Thanks Gerd! (2020-11-14)

James Malcom: This may very well be impossible to C+ with Gustav, but there is an alternative for manual/partial testing by using chess.com's free analysis. When you enter in the position, it completely agrees with the first full 14 moves. It ponders on 15. between which pawn to queen. If you manually enter 15. d8=Q, then the following engine evaluation generally agrees with the solution, and eventually is will find the mate on some point. (2020-11-06)
A.Buchanan: It’s not a matter of style whether you have space after comma in the solution. It’s incorrect syntax for the editor (2020-11-06)
