next challenge: make it short (#6235)
Good proof of legality in 94.0. See if you can shorten it to 74.0 or less.

EvinSung's 72.0 update of #6235 is most likely the SPG. Excellent work.

"most likely the SPG" ++ I doubt that
"Excellent work" ++ sure

I should say "possibly the SPG" in anticipation of a shortening from tygxc.

I don't think it can be 4 moves shorter but here's one that's 2 moves shorter. Proof game in 19.0.

I shouldn't have doubted EvinSung.
Now I'm just waiting for tygxc's shortening of #6235.
The last 5 positions are so satisfying for some reason.
Analysis couldn't find the mate in 9..
