Richter H. Gruber "What a correction! Making the previously cooked R5 sound (hopefully), the author simultaneously improved it substantially : Instead of 'only' two, now we have three capture-free black circuits (Dd8, Ta8, Sb8). Everything is based on the need to capture sLc8, and it is achieved virtuously. It is not apparent that sTa8 and sSb8 have to move at all. This makes R5v clearly superior to a number of related tourney entries showing multiple switchbacks (cf. 3rd and 4th Hon. Men.). "

paul: Correction of P1000446 (2022-02-06)
Henrik Juel: There is a funny english error in the judge comment
He probably wanted to say that the author performed like a virtuoso, but wrote 'and it is achieved virtuously.', which has a completely different meaning (2022-02-06)
A.Buchanan: This is very impressive. (2022-02-07)

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
