White can win but agreed to a draw after 55.Qd8+
Now, in C.N. 8150, Peter Anderberg (Harmstorf, Germany) gives the solution to the puzzle:
White: Nils Lie (from SkÝrping)
Black: Arne Desler (from KÝbenhavn)
The Danish OTB Championship 1930 in Svendborg ended with a clear victory for Erik Andersen Sr (5.5/7, +4 =3 -0) ahead of Lie and Desler with 4.5/7 (both +3 =3 -1).
So as tie-break, two correspondence games were played. The position above is from the first one (game score submitted to the database). The second game was won by Lie after 50 moves who had Black in a Ruy Lopez.
