Chess problem 52, and the "null-move heuristic". / Schachaufgabe 52 und die "Null-Zug-Suche".

Very very interesting position. The first move that comes to my mind is Bd2, but after Qc7+ I do not know what to do.

      I think this position is easier than it looks like and more when you only have to check the king. What about Rc3 attaking the Queen? If black take on c2:

      1. Rc2 Qxc2
      2. Bd8+ g5
      3. Ba5 (Threatening checkmate on e1) Qf2
      4. Bc7 (Threatening checkmate on g3) Zugzwang!
        The Queen cannot move from the second row and has to defend the diagonal e1 - h4

      Your solution looks good! (1....Rc2 first, Rc3 is an impossible move). If Black plays 1...Qb8+ (instead of Qxc2), then 2.Bc7 - Qb3 3. Bd8+g5 4. Rc4 - Qxc4 and 5. g3 mate. But I think you found the key ideas.
