    That's what happens when you promote the Siamese pawn.

    Promoted from the only missing pawn, the black one?

    That was back when promotion rules weren't that strict. ;)

    Yes, you could promote to an opponent's piece, but black had two bishops on the same colour squares as well.

    Solved 287/290 :D

    actually chuck norris just pushed 2 black pawns bakc at the beginning of the game and made a black bishop and a white bishop

    thats why black has only 6 pawns

    "Insert position or game" button on the top left side of the message box where you write your comments. From there, you'll have to kind of read the instructions. PGN codes can be obtained from any game on chess.com, and I believe it's FEN strings to play from a particular position. Like I said, the rest you'll figure it out as you use it a few times.

    Actually, because it is a composition, the 50-M rules does not apply (unless you were to present it as a retrograde problem :D).

    Tablebase results in themselves are neutral as they could be used both in actual chess games as in compositions and this could render different outcomes. But the verdict on your composed extension is unambiguous - no 50M rule!
