Speaking of making the proof shorter, actually, I just improved n9351I1's proof down to 29.5 turns! Broke the 30 turn barrier, hell yeah! Anyway, I'll wait and give other people a chance to try and figure out how the proof works before I post my solution.

We haven't seen your game yet, but it seems you and tygxc are tied for shortest at 29.5 moves. That makes me think it's not getting any shorter. While tygxc continues to work on improving  his current 61-move game for my position at #478, maybe you would like to take a shot at the position at #570. It's the same as #478, except with a white queen at e2 instead of a black knight.

@tygxc not how I did it, but that's neat! I like how you used the queen for the capture on f1, up until then I only ever considered using a knight.

After seeing your solution, here's an even faster one I came up with:

I really think you're getting the hang of these proof games. #570 may not be too much of a stretch.

This shows it's legal. Now it needs to be shortened.

IF YOU LOOKED AT MY 'FUNNIEST GAMES LIBARAY' YOU WOULD GET THE ANSWER IMMEDITATLY. WORTH 5 TROPHIES FOR SHORTEST PROOF. 1 FOR A ANSWER 3 FOR A FASTER ONE

It can be shorter. Key is to tame the white quadriga Nb1, Ng1, Nb8, Nc8. The motions of the white Rh1 and Bf1 can be better. The black king can enter h5-h4-h3-g2, so that white can play h4 in 1 move only without h3 first. I look at these ideas first before I attempt #570.

How are you doing with improving your 61-move game?
