No I didn't lol, I just said the proof games should always end in black making the last move so that it's a full number of moves.

But if that became a requirement, it would be a very weird change.

To be more accurate, there is a person who wants full moves.

(Posted in response to EndgameEnthusiast's deleted comment that "people want full moves".)

Rg1 is just included to spite endgame enthusiast, yes?

I find Endgame's logic funny since the following are apparently against the rules:

  • Any games that end with black resigning.
  • Any endgame studies that end with a white move (most studies.)
  • Any game where white checkmates black.

What is "Endgame"? What is this discussion about? Which post?

Resigning is technically a move by black, so I'm fine.

Actually with studies I prefer they begin with white to move, just as white begins an actual chess game, so therefore I prefer they also end with white to move. Any study that starts with black to move, the position can be inverted where white has the pieces.

Resignation is not a move. It's a action outside of the possibilities on the board itself. The starting position has 20 moves, not 21.

I still have no clue what "Endgame" refers to - probably not "endgames". But I know that "resigning" is commonly unacceptable in compositions. Otherwise black could e.g. destroy all selfmate compositions by resigning on move 1 of the intended solution. The composition field does better with only automaticities and no interventions by arbiters or player claims.
