qb2-a2 means an illegal check, same with bb2-a3 and e7-e6

Yes. I overlooked "white to move" and was working on a proof game for the black to move case, which is not simple. I guess this was another obviously illegal position.

me too

i also didnt notice that black has no legal moves

I don't much like the positions that are only illegal because the side to move was stipulated. I prefer the ones that seem legal and require careful reasoning to prove illegality, without any requirement that a particular side has the move.

lmao... it's easy to stipulate which side has the next move. Just put one of the kings in check grin.png

Edit: Gee golly, I took the 5000th comment? Lucky me!

I went ahead and finished the proof game I had started on for #4970. It's a shame EvinSung turned a decent shortest proof game challenge into a trivial illegal position challenge by stipulating White to move.
