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:  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

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
https://www.thbrand.de/downloads/5rbtt_fuddled.pdf

Please send you entries until March 31, 2020 to me; Bernd will judge the tourney. Much fun and good luck! – Thomas Brand
