Thank you for this. What does "Anonymous Tourney" mean, please? What is the Shedey Theme?

Shedey = Lacny cycle incorporating the threat.

Andrew, problems sent to formal tourneys usually come to judge in anonymous form. However, it is not always so.
This announcement uses words "closed tourney" as translation from Russian. I hoped "anonymous" would be more clear.

Yes, it can lead to bad bad misjudgment. In my 25 JT Richard Becker sent a study that I downgraded because of partial anticipation by Richard Becker.
So, as a word of advice: Don't send in matrixes you used previously.

Also, as a historian, I would be very intested in a biography of Mr. Shedey. Can it please be provided in the award?

Actually, it is not clear, if the organisers had in mind so called threat Lacny under the name Shedey theme. In my view, there is often confusion between two different themes somehow bearing name of Sergey Shedey.

Shedey cycle (according to PG Cyclone) = cyclic change of threat and two mates after two defences - see e.g.

Shedey theme (according to MV&KV Encyclopedia) = double DOmbrovskis paradox with identical mates - see e.g.
