Reported by Michel Caillaud:
Christian Poisson just released a new version of Winchloe with improved solving for proofgames.
On his site can be found a booklet with 562 (!!) original homebase PGs and some explanations: http://christian.poisson.free.fr/problemesis/problemesis.php
From Readme of v.3.46 (oct.2019)
Solving of proof games (‘partie justificative’) is a little more “intelligent”. A new option in “Solving options” allows you to choose whether short solutions are sought. In this case, a solution in p moves will not be sought if there is a solution in p-n moves (n integer).
I composed some simple proof games to check the programming with several fairy conditions. They are gathered in a pdf available on Problemesis.
Winchloe is (sometimes much) slower than Jacobi, but it is interesting for conditions not implemented in Jacobi, as it is sometimes much quicker than Popeye.
Such the case is for Take&Make, and in solving the 8,0 first moves of 550(1), Winchloé finds the cook :
1.d4 Sç6 2.Bh6 g×h6(ç1=S) 3.Sd2 S×é2(Sé4) 4.Ba6 S×d2(Sb3) 5.a×b3(d2) b×a6(f1=B) 6.R×a7(Ra5) Sé5 7.Qf3 S×f3(Sb7) 8.Sé2 Bg7…

5th Retroblog TT on Fuddled Men proofgames
With “Fuddled Men”, no unit can make two moves in succession. This restriction also holds for the effect on the opponent’s king.
In an article Bernd Gräfrath demonstrates this fairy condition with six original proof games, and in order to encourage the further exploration of this thematic field, the Retroblog announces a thematic tourney for proof games with Fuddled Men. Both article and announcement of the thematic tourney you will find at
Please send you entries until March 31, 2020 to me; Bernd will judge the tourney. Much fun and good luck! – Thomas Brand
Quick Composing TT-232 by SuperProblem
Tourney name: “…and now it’s time for half-neutrals!“
Stipulation: #2 (fairy)
Theme: In the initial position or after the key move of #2, there is at least one orthodox half-neutral piece in neutral phase.
The thematic half-neutral piece should play at least 4 times, in the following way:
1) it should be played by White to give at least two mates on different squares.
2) it should be played by Black to at least two different squares, leading to different mates by White.
The thematic variations can be split between phases (set play, tries, actual play, twins) but zero-positions are not allowed.
It is also allowed to use the thematic piece as front piece of a battery.
No other fairy pieces and conditions are allowed, except orthodox half-neutral pieces.
Judges: Vlaicu Crişan, Julia Vysotska, Marjan Kovačević. | Closing date: October 24, 2019 | Download the announcement in English
Entries to Aleksey Oganesjan via e-mail: email@example.com. All received problems will be presented to the judge in anonymous form. Award will be published on the website http://superproblem.ru.
