Which king gets mated? If you mate one do you mate them all?

Ugh mine too. Preach!

This is not something for any computer to solve because you have created something very unreasonable to be solved. You can have an extended board but why have more than 2 kings on the board? Needless to say this is a complete waste of time, with all due respect.

I agree.

Actually, I don't know about mate in 1, but there is a mate in 2 that most computers can't figure out because it requires retrograde analysis, something most computers don't possess the skill of. 

The below diagram is White to move and mate in 2.  There is no Knight move or King move that works.  The problem is, the solver is required to do retrograde analysis.  There is no way that the Bishop or the Knight could possibly have been the last move made by Black.  If the Black King were on g7 and it moved to h8, how on earth did the White Bishop get to h6 to deliver check?  The answer?  It's impossible!  Therefore, Black could not have moved his King last.  That means that the pawn on g5 must have been the last move that was made by Black.  That pawn could not possibly have been on g6 to start with as White would have been in check with Black to move.  Therefore, the last move by Black HAD TO HAVE BEEN 1...g7-g5.  Only NOW is the mate in 2 easy to figure out.  White's first move is 2.hxg6 (en passant!).  Now any move by Black is mate next move for White.  2...fxg6 is answered by 3.Nxg6# while any other legal move by Black is answered by 3.g7#

 

Isn’t that a Mate in three?

It's been over 3 years since I composed the position and posted it here, and I haven't seen any evidence to the contrary, so I guess I was right! wink.png

Not quite. White could simply take that knight.
