Shortest-proof-game challenge

Rewan, did my 70-move proof game for #478 give you some ideas for shortening it?

I guess I am the only one who is confused after seeing this.

Did you look at the position at #478 and the proof game at #494? What do you find confusing?

In case Rewan or anyone else is working on #478, here's an update. I did a little work on my proof game at #494 and shortened it to 66 moves.

Find the shortest proof game for this position with White to move.

correct you will be awarded with 3 trophies!!

here another shortest proof game challenge!! worth 5 trophies!

azziling proof game cahllenge! worth 5 trophies!!! 

It should be worth more than 5 trophies to find a proof game for either of the first two positions you put at #509, since they are both illegal.

If that 90.5 move "shortest" proof game gets 3 trophies, how many for this 80 move game?

THEY ARE POSSIBLE. THEY ARE JUST HARD TO FIND

INCORRECT

you might say HEY NOT FAIR. think outside the box. i already gave u 4 trophies. super simple. if you find it i will give u 1 more tophy. REMEMBER THINK OUTSIDE THE BOX

I can't tell what you're talking about. I gave you an 80-move proof game for #505. If you have a shorter one, please post it.

At #509 you posted a position with 18 white men. Then you replaced it with another position, which I claim is also illegal.

Which position is it you want me to think outside the box about?

I do not think this position is legal

It is not achievable

A lot of illegal positions have been posted here. Since you didn't say which one you're referring to, you might be right.

the one 80 move ppost you posted is INCORRECT. hint: look at the sign. it says 1/2-1/2. hope that helps
