Mario Richter: In der Lösungsbesprechung wurde die Forderung präzisiert: Wieviele (und welche) Steine zogen in der KBP mindestens?
Die richtige Antwort ist: 6 (sSb8, wSb1, wDd1, wKe1, wSg1, wTh1).
Die kürzeste BP braucht 12 Züge von Schwarz (Sb8xLc1-f3xTg1, dann zurück nach b8), wK und wSS können nur gerade Anzahlen von Zügen machen, wegen Th1-g1 muß also wD oder wTa1 ein Tempo verlieren. In Rahmen des 12-Züge-Limits schafft das nur die wD. (2010-05-24)

Bei 16.5, 17.0 keine Lösung. BP 18.0 64 Lösungen.
C+ Euclide 1.11 in 44 Std. 07 Min. (2023-01-10)
A.Buchanan: This is a cool problem with tempo loss for both players (bK9 & wPf2). Noam likes to end proof games with checkmate, and in this case I guess it serves to eliminate shorter solutions which would otherwise save half a move. Checking 16.5 is sufficient for soundness. Thanks for taking the time to test. (2023-01-11)
A.Buchanan: Bit baffled how there can be 64 solutions in 18.0 moves since White just moved. 18.5 maybe? (2023-01-11)
ras@bsiag.com: Quickly checked because 45h seemed a lot for only 17.5 moves and only a few captures: Stelvio 0.98 is done in 210 seconds. (2023-01-11)
ras@bsiag.com: Well, Stelvio treats shorter solutions of same parity as cooks, so any shorter solution in 16.5, 15.5 etc would have been found by checking for 17.5. But anyhow, quickly checking 16.5 is done in a few seconds, finding no solution (of course). (2023-01-12)

Pronkin-Thema mit der eingeschlossenen sD. Ein sS könnte a1 nicht mehr verlassen. Ein sT könnte h8 nicht mehr erreichen, und von a8 kann kein sT auf b3 geschlagen werden, da dazu der sBa7 zuerst nach a5 müsste und damit der wTa1 nicht mehr ohne Schlag des sBa nach b5 kann.

Mario Richter: brauchen wir wirklich zwei verschiedene Keywords - hier "Tempoverlustmanöver", bei z.B. P1007491 hingegen "Loss of tempo"? (2018-10-21)
Henrik Juel: Good point, Mario
Other things in the never-ending Keyword discussion include:
Tempoverlustmanöver is currently called the same in english and french, and has no definitions
Loss of tempo (Tempoverlust in german) is defined as
'With White to play, a sequence of moves to reach the same position with Black to play. (Help game, abbr .: TV)'
which makes little sense in proof games
In this problem [Pe2] goes e2-e3-e4 ('wasting' a move)
In P1007491 [Pc2] similarly goes c2-c3-c4-... and [Lc8] goes (among other things) c8-b7-a6-c8 ('triangulation') (2018-10-21)
Henrik Juel: There are many solutions in 6.0 moves, like
1.Sb1-c3 Sg8-f6 2.Pe2-e4 Sf6xe4 3.Sc3-a4 Se4-c3 4.Ra1-b1 Sc3xb1 5.Sa4-c3 Sb1-a3 6.Sc3-b1 Sa3-c4

Henrik Juel: The position can be reached in 18.0 moves: the first 3.0 as above, then Black plays as above, while White plays f3 and 14 tempo-moves like Sh3-g1.
Changing the stipulation to 'Proof game in exactly 18.5 moves' may rectify the situation.
The intended White play is very nice: Roundtrip by Ke1, needed by the triangulation on e3-f4-f3-e3, and roundtrip by Sg1, which screens on d4. (2011-03-14)
A.Buchanan: The preferred trick in such situations is to add an extra half move. So I'd try 19. ... Lg8: is that sound? (2017-09-14)
Henrik Juel: I tried to test 19... Lg8, but Euclide was too slow (2017-09-14)
Mario Richter: rawbats say that appending 19. ... Lg8 allows many alternative solutions, e.g. 1. c3 h5 2. Da4 h4 3. Dc6 dxc6 4. f3 Lf5 5. Sa3 Lh7 6. Tb1 Dd4 7. Ta1 Da4 8. Tb1 e6 9. Ta1 Se7 10.

rawbats also says that Henrik's suggestion of changing the stipulation to 'Proof game in exactly 18.5 moves' will make the problem correct. (2017-09-18)
Mario Richter: I forgot: ... but since "loss of tempo" is the theme of the problem, this change of stipulation is IMHO not an option here. (2017-09-18)
A.Buchanan: Thanks Mario, and I agree with you about the aesthetics of change. After posting my Lg8 suggestion, I did regret it because it's doubly suspicious. Firstly, the bishop can sneak past bRh8; secondly it takes the bishop's eye off d3 & c2. A more serious guess is to replace the last black moves by 16... Rh6 17... Sf8 18... Rf6 19... g6. This might fail for what in my head I call the "jigsaw" reason: that the known sub-chains of moves no longer mesh together in a unique way, but I don't think it fails for any other reason. Prove me wrong, stout rawbats! :D (2017-09-18)
A.Buchanan: Sorry Henrik I should also have said thank you for trying to validate my dumb earlier suggestion :-) (2017-09-18)
A.Buchanan: Typo, I meant: 16... Rh6 17... *Sh8* 18... Rf6 19... g6 sorry :( (2017-09-18)
Mario Richter: with the last black moves changed to 16... Rh6 17... Sh8 18... Rf6 19... g6 (final pos: 7n/pppnkp2/2p1prp1/2b2b2/q2r3p/2P2P2/PP1PP1PP/RNB1KBNR) rawbats thinks the problem is correct (2017-09-18)
A.Buchanan: Thank you, Mario. Obviously the composer could easily have fixed this if he was aware of the concern. His KS round trips are fantastically meandering, and the precise W&B play are very interdependent. I am amazed that there is only one composition in PDB by this top level composer, so I've found another to post quickly. He has a website http://open.mixi.jp/user/10857363/diary, with lots of erudite commentary in Japanese on top Western retros. Thank you, google translate! (2017-09-18)
