Originally posted by SwissGambitI thought I had covered that before - only three white units have been captured, by exf6, fxg5 and gxh4. There are no more missing white units that could have been captured on b2!
So far, so good. There is only one possibility you did not consider. What if bQ just captured something on b2?

Originally posted by SwissGambitOK, I didn't realise that. I thought we had to prove that b6-b5 must have been black's last move, not just that it might have been.
It's legal. However, it is not the only possible last move. Convention is that white may only play e.p. if it can be proved that black's last move was b7-b5.
Originally posted by Data FlyThat had been mentioned in previous posts, but the point that it denied the possibility of uncapture on b2 had not been mentioned until now.

SOLV'D.

Great. It that case, here is my puzzle. Mine is just an endgame technique one. White to play, is there a win with best play, and if so show all the winning lines. If it is drawn, show black's drawing technique:
[fen]6k1/6p1/8/5KPP/8/8/8/8 w - - 0 1[/fen]
Edit: in that last viewer, if 2...g6 then 3.Kxg6 (not 3.hxg6 stalemate).

Hi Data,
Well at least you solved it and he solved yours - trouble is Miss Gambit
now gets another chance to post another puzzle. I hate him....
Ruxton used to give me all these studies everytime we met.
Sometimes right after a league mtch. I hate him as well.
I'd like to maroon the both of them on a desert island with just one
chessboard and one Black King between them.

Thinks that would stop me.
I'd just do an illegal cluster. Black K only on the board. Add pieces for an IC.
(An illegal cluster is an illegal position that would be legal if ANY one of the pieces (besides a King) was not on the board.)
Example:
Add 3 white pawns for an IC
Solution:
Illegal - where did the black Rook come from to deliver check? All routes are barred, unless one of the white pawns is removed.
Now, the one you guys get to solve.

Add the wK and 8 wP for an illegal cluster

Edit. Oh I have to use all eight.
I've never heard of an Illegal Cluster before. At first I thought this was one with five white pawns:
However it might be Black to move after White has just captured Black's last piece (e.g. Qxb1), or is it always White to move in these puzzles?
In any case, clearly the solution to SwissGambit's problem must involve the white queen somehow, and at the moment I can't imagine how.
