WinChloe: cook in 1HM No.550.1

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: 

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

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

The 19th Japanese Sake Tourney Award

Theme: H#2 Point Reflection. Fairy pieces and/or other fairy conditions are not allowed.


The 19th Japanese Sake Tourney


We received 65 problems, a new record for our Sake tourney. The level was very good overall, in spite of the lack of outstanding problems. We decided to give 4 Prizes, 3 Honorable Mentions and 14 Commendations (without order). The new condition Point Reflection, which was invented by a young Japanese composer Hiryu Todoroki, got praises from many composers as “great,” “inspiring,” “very interesting and promising.”

Tadashi Wakashima, Toshiki Kobayashi and Hitoshi Yanami


Theme: Helpself compositions (hs#n/hs=n) with at least three (stale)mates by the same piece on different squares.


Tzuica Tourney 2019


69 problems by 35 composers from 14 countries have taken part in this tourney. We initially thought that the theme was rather difficult, but the number of entries seems to have proven that we were wrong. As usual we awarded problems that showed the theme intensively and we praised rich strategy as well as a good and pleasant construction, with all white or black officers used in the solutions. Interplay must also play a role in the solution. Some entries with small constructional blemishes, such as unused white / black figures in at least one phase have been sadly left out of the present award. We hope, however, their authors will be able to find out improved settings and even win prizes in other tournaments.
