#1852 - 26.0 move proof game

Only two moves to go. The position is a prize-winning composition by Unto Heinonen, so the 24.0 move solution will be unique.

EvinSung, you need to say whether you're still trying to shorten this proof game or have given up and want me to post the SPG.

Here is a fairly short one which may not be too difficult. What is the quickest way to reach this position?

I'll report when someone posts the shortest game. This is not it.

#1866 - 14 move proof game

That's an improvement, but still not the shortest.

I don't think anyone can improve on EvinSung's game at #1869 (57 moves).

Thanks, I didn't remember #87. And it was only posted about ten years ago.

EvinSung needs to say whether he is still working on shortening #1852 and #1866.

Ilampozhil25

just went through (still going) the whole thread and noticed the similarity

 

and wow 2012 is 10 years ago!!!

ya

that is like the most obvious position ever

all the pieces just.. go to their spot

only intricacies are bb5 and qh5 might be check and black needs to 0-0 but otherwise insanely easy

i find this more pleasing, the queenside-kingside placement of pieces
