An ode to coffee (for Marcos Roland, 2016)

Original publication: Facebook, 4 September 2016
When Marcos Roland challenged me to write a short poem about coffee, this is what I wrote, and I would like to share it with the MatPlus community.

An Ode to Coffee, or: Do they know it's coffee time at all?

Dedicated to Marcos Roland

The nectar of your roasted beans
runs down my throat, a drop my chin,
you come in many different tastes
you give me strength when I must haste.

Coffee, my ambrosia
you are my Anastasia
you are my power in the night
or when the sun still shines outside.

I hail to thee, but let us think
for just a moment at the brink
of our consciousness of the slaves
that reap those beans until their graves.

Let's find a way to populate
but not genetically manipulate
the coffee so that it may grow
wherever in the north we sow.

Let's give them wealth as they give there
more of the work than they can bear
so that not only we can say
coffee again made my day!

Since Mozart wrote his C-A-F-F-E-E, wouldn't it be
obvious to compose a chess problem with an analog theme
(maybe the pieces stand on c1 a2 f3 f4 e5 e6,
what do I know, use your creativity...)?

Is there a melody for it?

scheme-example, study

White to play, black wins

f7!=) (5... Rxe5+? 6. Kd6 Kf5 7. f7 Re6+ 8. Kd7=) 6. Kd6 (6. f7 Rd8+-+
(6... Rf8-+)) 6... Kg6 7. f4 Kf7 0-1

Without artistic importance, but with unique solution.

Another possibility:

@Viktoras: nice move 2...Bh6 and ideal mate!

This is so close! I had to add bPh6 to prevent 3.Qh6.

It seems that in helpmate genre is more artistic opportunity. Bravo for authors of these problems!

Here I publish once more in ortodox manner. I am not satisfied with the most of my problems (schemes) here (see also previous post), but I want to attract other composers to join us.
