WCO 2018 – Batumi, Fairy Award

FIDE OLYMPIC TOURNEY – BATUMI, 2018
AWARD – FAIRIES
JUDGE: PETKO A.PETKOV

From the tournament director I received 41 originals by 23 authors from 10 countries.
There was no limit to the number of problems an author could send (a novelty for this tournament!). This fact does not bother me. However, I would suggest in the future that in such cases a maximum of 2 or 3 problems in a section must be set.
I’m glad to say that the level of the competition is very high! This assessment, of course, applies in the highest degree to the problems awarded with prizes.
I express my gratitude to problem-friend Geoff Foster for the English version of my text!

Jacobi equipped with constraints… (Michel Caillaud, Nicolas Dupont, François Labelle)

Jacobi: constraints

An article by Michel Caillaud, Nicolas Dupont, François Labelle explains and illustrates a new tool to solve some complicated fairy PGs offered by the solving program Jacobi – the possibility to add some constraints in the input.
(with gratitude to the authors for offering this article to JF)

…Jacobi constraints let the user specify some or all of a piece’s moves. One design goal was to be able to represent the “strategy” notation displayed by Natch and Euclide when solving a proof game, so the notation is somewhat similar. This common notation includes the “-” and “x” symbols, and a minimum number n of moves played by a piece is marked “(n)”…
