Hi
Trust Ruxton to drop that one in your lap in a thread with tactics in the title.
First of all I'll lay it out correctly, I hate sloppy lay outs, there is no need for it.
I went to all that trouble to write the code to give you FEN's and PGN's (Posting Geoff's Notation.)
and you guys never use it.
(Keith you know better than to give these guys a position to set up in their head,
even a simple one like this. And puzzles like this are never going to be popular because
they cannot switch on the Fritz to solve it for them......though no doubt some have tried.)

"One of my favourite puzzles is a game where the normal rules of chess apply but there is
one additional rule:
No piece can move from a square of one colour to a square of a different colour
(so knights can never move, bishops work as normal etc.)
The position is a black king on e8, white king on e1, white pawns on f2 and d2 and a white bishop
carelessly placed between e3 and e4.
The question is: which square does the bishop stand on, e3 or e4?
[pos]4k3/8/8/8/8/4B3/3P1P2/4K3 b - - 0 26[/pos] [pos]4k3/8/8/8/4B3/8/3P1P2/4K3 b - - 0 1[/pos]
So given the conditions as stated above, which diagram is correct?
As stated it must Be3. What took the last Black dark squared piece?
It cannot have been the White pawns or the White King, it must have been the dark squared Bishop.
Someone said;
"So, you can see very readily that it would be impossible to reconstruct every move of the game
- known as a proof game."
Took me all of two minutes and is the clumiest piece of retro you will ever see.
But given time I reckon I can shave off 5-6 moves, maybe more. But it can be done.
The problem is sound.

Over on Red Hot Pawn I'm in a problem club run by a Retro King - I'll see if he is
interested in knocking the proof game down to under 20 moves.
Andy why does the PGN thingy thing start automatically moving right away.
By the time they read as far down as the PGN the game is half over and the
reader has to re-set it. This is sloppy.
Tweak it so the reader can start the PGN off when he is good and ready.
I can see I'm going to have make a regular visits here. You lot have become sloppy.
BTW my plastic Duck is now in New York and has even visited the Marshall Chess Club.
