Fleck with battery


A terminology question. Fleck, for obvious reasons,
ruled out batteries in his theme. Now observe:

(= 4+5 )

1.Bf5! gxf2/Bg1/g1X 2.Rxg5/Rh4/Rxg3#

R~ is never a threat, there are no random battery moves.
Would you, thus, count this as a Fleck "in spirit"?

yes. I consider it genuine fleck.

Certainly it's a Fleck.

Where did Fleck rule out battery mates? The chess problem world seems to have decided otherwise. Morse's task book gives the records as 14 threats with a battery and 8 without a battery.

Did Fleck claim to have invented a new theme? That would seem strange, given the number of earlier examples. In The Problemist I recently quoted a Fleck which Lilian Baird published in 1891, when she was 9 years old.

Now we *really* need a reference pointing to an article of Fleck
on the matter.

Fleck with battery is easy to compose (though difficult to have good key) so it is not usually considered special.
