[Retros] [tros] chess puzzle

Noam> Any idea who is the composer and 
Noam> when/where this study was first published?

I don't know if it was published as a study,
but it can also be viewed as a #5 problem:

1.Qh2-h6! threatens 2.Qxf8+ Qe8 3.Qxe8#  

Andrej J.> But what after 1. ... Qe4 ?

This doesn't defend against the threat ...

The longest variation is:

1. ... Qf5 2.Qh1+ d5 3.Qxd5 Qxd5
4. Nxd5 Nd7/Ne6 5.Nc7/Nb6#
