    When solving with Popeye have got the check on the last move, 10.Sb1-d2 e3*d2 + dia , while it is pin mate in fact. If I may write C+ still? What might be the reason?

    > What might be the reason?

    The reason is that Popeye only tests for checkmate when it is told to, most often to test find out whether the mate goal requested by the stipulation is reached.

    Testing for mate in proof games would be a waste of time.

    Jacobi+ (with checkmate on the last move).

    Sometimes it’s crucial to know the full effect of a move. The legality of play might depend on ‘which side is in check’.

    For instance,
    The LEGAL solution of b) should start with 1.Kg5+!!!

    Or a simpler position which could be legal if the side having the move is in check:

    Black Be7 Kg5
