Re: Godzilla Endgame Chess Puzzles (1)
With 6-men Syzygy.
I can confirm that even with 5-men Syzygy the solution is not easily found.
Looking at the variations, I think it's because of this kind of 6-men position:
[D]rn2R3/8/8/8/8/1PK5/8/6k1 w - - 0 6
Won for white, but you need a deep analysis to prove that without tablebases. The winning variation from this position is quite subtle, with the pawn providing coverage for the white King against rook checks.
Very pretty!
