JF Retro 2015-2016 — Award

 

Julia’s Fairies • Retro 2015-2016 • Award

by Thomas Brand, D-Bornheim

I’m very grateful to Julia for her invitation to judge this interesting fairy retro tourney: I’m convinced that carefully selected fairy conditions (more than fairy pieces) will extend the options for interesting retrograde analysis in the future. The most popular current example is AntiCirce with defensive retractors, but the general idea goes back to Thomas R. Dawson (whom else?), and gets more and more popular. → to the Award…

Published with a gratitude to the judge, Thomas Brand /Julia/

JF new logo and more…

I’m glad to present a new logo for JF! No, no, not my work, a professional one. 🙂

And together with a new logo, a new look of Original Problems page, the one you can see if clicking on the  upper menu. It’s not only about the list of informal competitions presented in the table now, but also about the links to the Awards added for each competition for your convenience (I hope!).

The Judge of JF fairy tournament 10/2017-03/2018

After a long time… the one who was the first judge ever of JF’s fairy tournament, had to analyze about 200 fairy problems and finished the Award in a year after competition, is kindly accepting this job again! I’m very glad to announce the judge of current fairy tournament, JF-10/2017-03/2018 – famous Indian composer, International Master of FIDE – Shankar Ram! To the words I’ve written about Shankar in 2012, he’s added the following: 

  • From 2012, Got back to composing, judging, article writing, getting in touch with chess problem friends
  • Current interest: Acquiring new gadgets and porting Popeye to them!

Wishing a pleasant work for the judge, and creative ideas to the authors! – Julia
