Proof Game in 14.0 moves
(Position after Black's 14th move. How did the game go?)
Trying to have a go at one of these proof games for the first time.
R on c4 must have moved three times if from h8, B on c3 twice, other B once, Q twice, N on e7 once, eP once, f pawn 3/4 and g pawn 1/2.
As only 14 moves allowed those last pawns must have moved two squares initially. No captures possible.
Also therefore a white N must have captured the P at d7 and R at a8.
I've also noticed that the bN is four moves from the R, the gN three from the P.
So the order of blacks moves.
eP after wsB, but before Q, which is in turn before N.
bsB first move before R at all, but after gP. 2nd move last to allow N back.
But gP is after Q 2nd
I'm thinking that prior to N must capture the d7 P ASAP, i.e. on move three. fP can safely move twice before this, but I can't yet see a third move which black can then play before the N vacates its spot.
Random thoughts. Working on it, board out.....
Edit: And this post did take a while. Having caught a little of Mephisto's reply, I was able to figure out the rest of the moves quite quickly. Biggest problem seemed to be missing Qd5 (not Qg5).
