Not entirely perpetual check


H. F. L. Meyer

(= 12+8 )

Mate in 7

Can somebody give the correct position (I inserted
a Pc7 but maybe the potential cook Rxc5+/Qb8+ is
warded off otherwise) and source?

The following setting is given in "The Chess Bouquet" (1897). Unfortunately like most books of the period it omits source details.


H.F.L.Meyer

(= 12+7 )


Mate in 6

1.Sh4+ Ke5+
2.S2f3+ Sxf3+
3.d4+ Sxd4+
4.Sf3+ Sxf3+
5.d4+ Sxd4+
6.Bf4

The solution mentions that "The author has now embodied this idea in a ten-mover, which , therefore, has a succession of nineteen checks".

I can't help, sadly, but I'd like to show the records. In a study, I think the record is 15 checks (if I remember correctly, the idea was shown by Pogosyants in a study with 7 or 9 checks some decades ago).
