The last 5 positions are so satisfying for some reason.

Positions with black in check should be declared invalid for this thread, as a full number of moves could not have been completed in a game reaching such a position.

I hereby declare positions with Black in check as valid for this thread.

To fix the position above is so easy, all you have to do is replace the white knight on d2 with a black knight on e7, the white bishop on c7 with a black bishop on f2, the black knight on a6 with a white knight on h3...etc, and do this with all the pieces and you will have the exact same position but with white to move instead!

That's pointless work because positions with Black in check have been declared valid for this thread.

Now I'm just waiting for tygxc's shortening of #6235.
