I would like chess.com to allow for a way of obviating the Queen’s effect on pawn promotion besides it simply not existing or Crazyhouse/Bughouse, whereby it doesn’t need to be available to promote to even if it exists. Of the variants available on chess.com right now, I think I like atomic quite a lot in principle, because it adds a rule for pieces to capture or be captured by a means other than displacement, like pawns get to take each other en passant. It just comes out as an inflexible variant in practice, probably being difficult to combine with any other rule without breaking the resulting game.
I would like to win, however i will not be watching this.
