@bigdogg saidForgot to claim Ba6# is impossible from that position (since the bishop is already there.
If you mirror that position vertically, you get 1.Ba8#
@ponderable saidBut nothing is on a6.

@ponderable saidNo worries.
I apologize for completely mangling the problem. Please disregard all my posts.
I actaully was under the impression that the diagonal from a1 to h8 was described what is definietyl wrong...
@greenpawn34 saidThis one is tough.
Hi Ponderable
mangling the problem is my specialty. I've not given up.
Spent day at Dunbar visiting old friends and tonight have to get a team together
for 10 board for a league match tomorrow night.
(I always put this things off to last minute.)
@greenpawn34 saidSOLV'D - 1.Ba6# is the invalid move.
[fen]3R4/3B4/RB1k1BR1/3B2B1/8/3QB3/8/2B4K w - - 0 1[/fen]
1.Ba1# 1.Ba2# 1.Ba3# 1.Ba4# 1.Ba5# 1.Ba7+ 1.Ba8#
and the White Queen can reach c4. So 1. Ba6 is the bogey.
@greenpawn34 saidSeems like it.
I was thinking after I had isolated the a-file Bishop Ba6 mate and found
how to play Qc4 I could tidy it up a bit but I was only too glad to get it.
With the Black King on d3 the impossible move would be Ba3# Yes?
