Shortest-proof-game challenge

56.5. I'll try to improve on this later.

OMG please just make the last move kd5!!! Not only will that make it a full number of moves, the tree will look even better PLEEEEAAAASSSEEE!!!!!

The point was that the illegal position could be turned into a legal position by removing one unit from the board. You want to spoil that by changing the location of a remaining unit.

Try This

Here's a 35.5 move game. EvinSung will tell us how much shorter it needs to be.

Proof game in 24.0.

But it will destroy the SPG. Different last move and no mandatory capture on c5!

That's true. It's amazing how hypocritical our OCD can be lol.

Considerando che sia stata effettuata una valutazione: l'ambito del gioco d'azzardo è estremamente coinvolgente e le decisioni spesso vengono prese senza adeguata riflessione sulle potenziali conseguenze . Benché siano numerosi i casinò europei che accettano giocatori italiani, è importante sottolineare che non tutti sono equivalenti. Di fronte alla proliferazione di siti e portali dedicati al gioco d'azzardo e alle scommesse sportive, si osserva altresì una marcata disparità in termini di qualità.

Which one is the most fun?

Before trying any solutions, I would have to pick the third one, because we know it's going to end with a move by White.

Here's a hint for those who want to try solving Leither's three positions. (#6064)

1st - SPG in 13.0

2nd - SPG in 11.5

3rd - SPG in 13.5

Supposedly, this can be reached without white moving a single piece.

How's this?

Ends in a full move and 23 moves, a prime number! Perfect!!

You need to be more consistent. At #6054 you asked for a proof game in 57.0, but 57 is not a prime number. You of all people should realize that making a proof game in other than a prime number of moves is a violation of common courtesy.

Nice. Is it possible to end with a white move—hang on, is that Endgame outside my window?
