### Is there a twin?

#2

This rather simple #2 problem is in the Win Chloe database without any twin.
But, I recently saw it with b) wKa6->c1 ?!?.

The twin (if it really was published this way) seems odd.
Solving it, I couldn't help but expect the solution you'd get from b) wKa6->g6 (which is more thematic, even if the two variations lead to the same mating move). Also, b) wKa6->g4 is somewhat thematic.

Was there a twin published?
If so, was there only one twin (and not the 2 better twins)?

b)Ka6->d1 has 2 sols.
I guess such a set of 4 twins with 2 white Grimshaw should have been done.

As far as I remember there is only one twin ...
Piotr Murdzia probably remembers it too :-)

See page 6 (page no.84) in:

The list of the guests who were not welcomed is missing :)

It is possible that this solving contest only featured two of the twins.
Possibly even deliberately, to trouble solvers, by avoiding simple thematic analogies.

But, as a composition, it is difficult to believe that an easily achieved second Grimshaw twin would be left unexploited -- particularly difficult to believe, when you consider this problem earned a prize.

The wPa2 and Pg3 give it away. There clearly must be variations where they are used, so I believe the twin Ka6->c1 and Ka6->g6(g5) are both right, and probably also Ka6->g4(e2,f2,g3). Maybe even Ka6->b7(c7,d7) as a kind of antithesis.
