Hello!
I spent some time during Chrismas on Hirakaz's list of
eighth row mates. I started with knight mates. From 22
groups there 8 had 6.0 moves or less, so they are optimal
according to computer analysis. From remaining 14 groups
I was able to improve 11! Rather than giving my positions
immediately, I give a puzzle.
The groups that I improved are:
b (earlier record 8.0), c (8.0), g (8.5), bxa (7.0),
axb (8.0), cxb (7.0), dxc (8.0), dxe (9.0), fxe (9.0),
fxg (8.0) and hxg (8.5).
I dont give my new number of moves. You are welcome to try
yourself. Composing is much easier when it is is
guaranteed that that the old record can be broken. If
there is something left in 48 hours from now then I will
publish the remaining. Olli.
