RE: Chess problem 51 / Schachaufgabe 51

Hi @jaki01. Here my possible solution:

1... Re2+!
If White take on e2 with the King , white will lose the Rook, the Bishop and probabbly checkmate:

1. ...Re2+
2. Kxe2 Qxg2+
3. Ke1 Bb4+
4. Rd2 Qxd2+
5. Kf1 Qxd3+

However, if white take the Rook with the Bishop:

1. ....Re2+ 2. Bxe2 d3+ 3. Kf1 dxe2+ 4.Kxd2 Qd3+ Kf1 Qf2#
