Shortest-proof-game challenge

@6269

I think all positions are fine.
Since I have the higher rating I guess mine takes precedence. :-)

i believe all positions must end in half moves (for a satisfyingly symmetric vote of 1-x-1 where x is a large number)

ok

So 4 votes for it doesn't matter and 1 vote for it should be black to move..

Repost; white to move.

Are you sure the SPG for this position ends with White to move? Do you have a proof game, and are you sure it's the shortest possible?

This position is from a forum puzzle. I do not have a proof game. I'm somewhat certain black can promote 6 DSBs to reach this position.

Proof of legality, not at all optimized.

I'm thinking now you just want any proof game that ends with White to play, not necessarily an SPG. It's hard to be sure what you're after. Maybe you could clarify it.

Ideal even if it's Black to play when shortened as much as possible?

hi

Here's a proof game that ends with White to play. I'm not sure how much shorter it can be.

Proof game in 27.0. EndgameEnthusiast will tell us how much shorter it needs to be.

Shorter:

This position was posted by EvinSung in the Illegal Position thread. I'm posting it here to see if someone can improve on the 50.5 move proof game I made for it.

@6291

What proof game?
Black has all 16 men, so white did not capture anything.
White has 15 men, only the h-pawn is missing. So black made 1 capture: the h-pawn.
Black has a doubled g-pawn g3/g7, so black must have captured ...hxg.
Black cannot have captured ...hxg when only the white h-pawn is missing.

EDIT:
Now I realise... black has captured some piece ...hxg and then the white h-pawn has promoted to replace said piece.

can you shorten this to 32.5 or less

Proof game in 32.5.
