Fastest way to have only kings left on the board?

abivasu

Because you can get a draw by having nothing but kings on the board, what is the fastest way you can think of (you can control both your and your opponent's moves) that does exactly that.

[White "abivasu"]
[Black "abivasu"]
[Result "*"]

i can beat that

AussieRookie

You can't - that's the World Record !

nimzomalaysian

There are 30 pieces on the board other than the kings, so if I capture a piece every move, I need 15 moves to capture all the pieces. But the opening takes 1 or 2 moves, so I see why it's difficult to break that record.

ChessOfPlayer

If each move captures a piece (except the first two moves of course) then it is clearly impossible to beat as you cannot capture two pieces in the one move. 

AussieRookie

The game above was composed by G.Ponzetto from Italy in 2000 and he holds the Record for the fastest ever 2 Kings draw - 16.5 moves. It's unlikely to be beaten.

  The previous Record was held by Sam Loyd in around 1896 of 17 moves each.

That was fast.

abivasu

AussieRookie said that he was going for 14 moves, a player can't capture 15 pieces is 14 moves!

abivasu

Sorry about the typo. I ment " in 14 moves", not " is 14 moves".

nimzomalaysian

You know there is an 'edit' option right?

AussieRookie

O.K. then, 15 moves - but I realise my first move will have to be a damn good one ! Smile

Could somebody find the fastest way to have only ten Knights both sides and Kings on the boards? Little like in this thread: https://www.chess.com/forum/view/game-analysis/funny-horses-game

I did not tried to find the fastest way, I just played with the game.

There is a considerable history among problem composers about attempts to find a shortest proof game for positions with only two kings remaining. For serious composers, Ponzetto's game is just an interesting curiosity. It doesn't qualify as a valid proof game composition, since his solution is not unique, as required by current rules for judging chess compositions. In other words, there is more than one game leading to his final position. For example, White's moves 9 and 10 could be swapped without changing the result. There have been some unique 16.5 move solutions found under the condition that the FIDE Dead Reckoning rule be suspended.

To my knowledge, the best unique solution with no special conditions is a 19.5 move proof game composed by F. Labelle in 2012. That's the record you should try to beat if you want to become famous in the problem composition world.

I just can't get the edit option to appear on my iPad.

I'm finnally posting it.

Next thing is to try and find out how many permutations of the 30 move solution there is!!

Since we have a unique 19.5 move solution, and a non-unique 16.5 move solution, any new results about a 30 move solution would not seem to be of much interest.

By the way, abivasu's game is not a valid solution unless the caption "No Dead Reckoning" is included. Without that condition, the game ends in a draw after Black's move 28, with a knight still on the board.
