Is there a known record for the most possible stalemates in one in a legal position, for with and without promoted pieces? I did some constructing myself for a start.

For without promoted pieces, I found 105, counting different promotions as different moves.

[Title "me, chess.stackexchange.com 2/24/2020, Stalemate In 1"]
[FEN "kN6/P1PPPPPP/2P5/4K3/6Q1/2NBB3/1R6/R7 w KQkq - 0 1"]

For promoted pieces, I remembered a position from elsewhere on this site. I switched two pieces, made come counting deductions, and I arrived at a number of 205 moves for with promoted pieces.

  • Your "with promoted pieces" currently has 9 queens and 3 bishops, so it seems illegal.

  • What about stalemate by repetition? If you were to give the black king two squares to move between, you would have a huge number of different combinations that produce a threefold repetition...

    The first position isn't legal, there's no possible previous move for black. The third position is already a draw, since there's no possible sequence of moves that will lead to either player getting mated.

I managed to find the ultimate records in the Die Schwable Chess Problem Database.
