          Qd3 Bg3 I think, followed by promotion

            I think the definitive solution was already found further down the thread, but I think this could still work
            Qd3 Bg3 Nf4 Kh4 … at that point it becomes a sloppy chase but White takes an indomitable lead, taking B and a pawn easily

              Bg3 is a check, followed by black promoting their pawn to queen

      That’s what I would have thought, leaves the King nowhere to go and there’s nothing to block/capture the Queen.

    Bc6 Rb2 Trying to mate on g2 and defending.

    I’m not sure where to go from there, either bg2+ or nf4+

    Either case I can’t find a forced mate in my head atleast

      Good start. You don’t have to calculate all the way to mate in that line, White gets an overwhelming advantage.

      But more interestingly: What do you do after Bc6 Rb1+?

        Bishop moves to g2 checkmate of it doesn’t check the king.

        If it does then the king walks back towards the rook. Until it takes it or the rook doesn’t check the king ending the game

              In what position? After 1. Bc6 Rb1+ 2. Ke2 Rb2+ 3. Kd3 Black doesn’t have anything but spite checks. And if …g2, White can now safely go Qc1 with quick checkmate to follow via Qh6+ (since g2 is covered by the bishop).

      Nicely done! You solved the main (study) line. There’s other lines where Black actually holds out longer, but they’re much simpler to calculate.

      Unfortunately no. After 1. Ke2 g2 2. Qe1 Black has a simple way to win the queen, and after 2. Qc1 Black can at at the very least promote the pawn and there will never be a checkmate for White.

        Rb2 checking King
