As far as I know, this is the first example of a reflex proof game - if true it is therefore a new genre. Note that the condition Black reflex # might be generalized to White reflex and to Reflex when we sum up the 2 possibilities. It might also be generalized to almost any kind of goals (one for the black side and one for the white side, which could be different).

Remark that 8.f3 can’t be played instead of 8.Rh2 because of the reflex 8…Bg3#. The move 10.f3 shows that the promoted piece on square b8 is a Bishop or a Queen, as the above diagonal checkmate possibility must be avoided. After 16.Ka6 there is a new orthogonal checkmate possibility 16…Qb6# if the promoted piece on square b8 is a Bishop. As this reflex checkmate is not played but replaced by the capture of the promotion, this latter is necessarily a Queen, and hence a Schnoebelen one as it didn’t move before its capture.

This problem is Jacobi C+ according to the next version, to be available soon, which will introduce the possibility to check some new reflex genres. (Author)
