IV CACHAÇA TOURNEY


The Brazilian problemists attending the 60th Congress da WFCC announce the IV Cachaça Tourney. Unfortunately, we couldn't work out the idea and the examples for this tourney in the term prescribed in the schedule of the Congress. So, we don't present it as an "unofficial tournament" of the meeting, but we don't mean any kind of a "protest" against the rules established by the organizers, which, we are sure, were laid down with the best of the intentions.

Theme: “echo play” – same sequence of move lengths must be shown in all solutions in n moves, either in all White moves or in all Black moves (or in both, but this is not an exigency). Multi-solutions and twins are accepted (no zeroposition). No fairy pieces / conditions.

IV CACHAÇA TOURNEY
60th WCCC
DRESDEN 2017

AWARD

SOME WORDS BY THE DIRECTOR MARCOS ROLAND

This was a tourney for h#3-n, with at least two solutions. The thematic exigency was stipulated in the following words: “’echo play’ – same sequence of move lengths must be shown in all solutions in n moves, either in all White moves or in all Black moves (or in both, but this is not an exigency). Multi-solutions and twins are accepted (no zeroposition). No fairy pieces / conditions.”

I consider this an unusual exigency, and I must say that my first idea was to demand “echo play with echo mates”. But it seemed to me that so restrictive exigency would drastically limit the creative possibilities, apart from raising some controversy about the precise scope of the concept of “echo mates”. Anyway, I think that if some authors had stablished as a goal to combine “echo play” with echo mates, restrictive as it may be, they could have overcome the difficulties inherent to the theme, and the number of entries should be greater.

Fifteen originals by eleven composers of six different countries were submitted, and I think the tourney was a success, given the hardness of the theme, the little time to compose and the length (3 or more moves) required.

I would like to take the opportunity to sincerely thank to all the participants, distinguished composers which accepted the challenge, and produced some fine pieces of work. And I invite all to participate in the next issue of the Cachaça Tourney, in Ohrid 2018!

The ranking proposed by the judge, Ricardo Vieira, to whom I thank very much for his dedicated and hard work, is as follows:
