    Could someone that understands chess explain the answer to rule 16? I got it by just plugging in all possible moves until it passed but it seems like a dumb move that gets your queen captured for no real benefit.

    Spoiler

    The answer is apparently Qg6+ but I don’t see how this is any better than Qh5+ for example which would (presumably) be followed by g6 then Qxg6+ putting you in the same position but with one less pawn for black. What am I missing?

      I think because after that queen move and losing it, you follow up with the C2 bishop to G6 and it’s checkmate?

      It’s because it’s a shorter mate so the engine considers it a better move.

      Qh5+ g6, Bxg6 hxg6, Qxg6#

      vs

      Qg6+ hxg6, Bxg6#
