Though not a Black King-cross, the flights have a nice pattern- c4,c5 and e5,e6. Excellent helpmate!

As usual, these two experts go for the maximum effect with perfect analogy between the solutions. Another great problem!

This is a good helpmate, but it would be even better if all B1 moves would happen to e4.

True. But I cant see such possibility in this scheme !

Well, I have even tried it already and I know it is possible.

Rajendran Raju sends the following problem by Zoltan Labai, The Problemist Sep.2014 for comparison which also shows four unpins.

1. Rd5 Rg4 2. Se5 Rf4#
1. Re4 Bg8 2. Rf6 Rg5#
1. Ke4 Rf2 2. Bd5 Sc5#
1. d3 Sd4 2. Ke4 Rg4#

Another fine problem, but with the black unpin Ke4 repeating in two variations.
[Added later] As Vitaly Medintsev rightly points out, the WB is idle in the 1.Ke4 variation !
