play all play one stop play next play all
Henrik Juel: White has the move
-1... f4xLg3 -2.Lh4 f5 -3.Lf6 h3 -4.Lb2 h4 -5.Lc1 h5 -6.b2xLa3 Lc5 -7.e3 Ld4 -8.c5 Lf6 -9.c4 Le7 -10.c3 Lf8 -11.c2 e7xTd6 -12.Td4 Kd8 -13.d6xTc7, retract Td4 to h1, Ka8 via g6 to e1, Pd6 to h2, g3-g2, g2xLf3 etc. (2013-08-28)
James Malcom: Is the given retraction unique? (2020-11-08)
Henrik Juel: Unique up to 11.c2-c3, I think (2020-11-08)
Henrik Juel: One of my favorite retros with just kings and pawns
even though the retroplay is not completely unique (so my previous comment is imprecise)
R: 2... h3-h2 3.Lf6-h4 h4-h3 or 3... f5-f4 also work
but not R: 1.e3-e4? or 1.c5-c6?, and White runs out of pawn retractions
nor 2. e3-e4? or 2. c5-c6? f5-f4 3. Le5-g3, and same difficulty (2020-11-09)
Henrik Juel: In the forward play we have several temporal implications, e.g.,
e2-e3 before b7xLa6 before g2xLf3 before g3-g2 before h2xg3
d6xc7 before e7xd6 before b2xLa3 before f4xLg3
Thierry was inspired by P0008574 (2020-11-09)
James Malcom: I see the similarities as well. If Thierry's last 21 moves, stopping at 11. c2-c3 of course, are indeed unique, it seems to be the record for a kindergarten position? (2020-11-09)
A.Buchanan: I think the last 2 single moves are determined. Prior to that it could be f5-f4 or h3-h2, no? (2020-11-10)
Henrik Juel: You are right, Andrew
So, no record, James (2020-11-10)
James Malcom: Ah well then-the linked problem with 16 moves by Gerd oughtta be it then, from what I've searched so far. (2020-11-10)
A.Buchanan: Isn’t the retro record one of the Breyer versions by Thierry Le Gleuher? (2020-11-10)
James Malcom: As far as I know, the TOTAL retro record is, all from P1339006, by Theierry indeed: Type A, 100 moves, Type B, 101 with bP6-h6 & White to move, and, finally Type C, 102 with bP6-h6 and wSc7-a8. (2020-11-10)
James Malcom: For Type B, I meant "bPh5-h6." (2020-11-10)

Iwan Soroka: Großartig! (2020-10-15)
Mirko Degenkolbe: Eine sensationelle Aufgabe!!
Sie ist noch einen Tick besser als das Goldstück vom 8.FIDE WORLD CUP.
Der Autor hatte mir dieses Meisterwerk vorab gezeigt und ich kann immer noch nicht so recht glauben, dass das alles genauso funktioniert, wie es angedacht ist.
Fantastisch! (2020-10-15)
Gerald Ettl: In der Laenge eine AUW eindeutig zu zeigen war sicherlich nicht leicht. Das Goldstück vom World Cup kenne ich nicht. Ist die auch hier in der Datenbank zu sehen? (2020-10-15)

AB: I too made this one yesterday but alas on checking in WinChloe found that Francois’ software had got there first! This shows the utility of WinChloe and the power of Francois’ approach. And at least I can be grateful I didn’t try to publish!

This proof game is too long to be found by François’ general mining program, but he can adapt his program specifically to find ornamental problems such as this where the final positions are highly constrained and he can count whether any move is taking him nearer or further away from the right kind of position. The definitively unproductive lines can easily be pruned. Homebases and symmetric positions are also amenable to this kind of attack

See P1381496.
