Message-ID: <20080618140051.80D5CF600@abel.math.harvard.edu> Seen in _Rochade_ 3, March 2008, p.25 (umlauts transcribed as ae/ue; thanks to Mark Watkins for lending me his copy): Die Story aus meiner Rubrik ``Nachwirkung einer langen Silvesternacht'' hat sich dieses Mal im morgendlichen X-mas C abgespielt: Ein schon leicht angegrauter Herr, der ungenannt bleiben will, spielte als Nachziehender am Neujahrstag in der Slawischen Verteidigung eine ``fantastische'' Neuerung. Nach den Anfangszuegen 1.d4 d5 2.c4 c6 3.Nc3 zog der aelter Herr mit ``bierernster'' Miene Bb4???!. Die beiden Gentlemen spielten trotz dieses regelwidrigen Zuges bis zum 13 Zug weiter, als waere nichts geschehen. Der zufallig zuschauende russische IM _Peter Marusenko_ - er wollte seinen kommende Gegner erfahren -, traute seinen Augen kaum, als er mitbekam, dass der Bf8 trotz der Pe7 und g7 ``entwickelt wurde''. Der 48-jaehrige, noch von einer durchzechten Nacht leicht alkoholisierte Zaungast ging schnurstracks zu einem Schiedsrichter und teilte diesem mit entsetzter Mine ungefaehr folgendes mit: ``Hm, aehh, you know I'm a master! But what I have seen on board Number ... is unbelievable. Maybe I'm still too drunk to judge this position rightly?!?'' Natuerlich wurde dem ``Einspruch'' des Meisters stattgegeben und die Herren mussten ihre Partie wieder beim 4. Zug beginnen. My German is barely up to the task of deciphering this text, but it doesn't seem that IM Marusenko considered the possibility that the Bb4 might have been promoted ;-) NDE From Nicolas.Dupont at math.univ-lille1.fr Wed Jun 18 13:36:13 2008 From: Nicolas.Dupont at math.univ-lille1.fr (Nicolas.Dupont at math.univ-lille1.fr) Date: Wed, 18 Jun 2008 19:36:13 +0200 (CEST) Subject: [Retros] Mate by a pawn on lign 2 or 7.

I don't agree. A promoted piece captured by an officer is also paradoxal, as it is "invisible". Another criticism would be that a Schnoebelen is much more difficult to construct than a half one. More is clear but much more not so... Indeed the record by the same side is 3 each time (Of course 3 Schnoebelen is a masterpiece and 3 half only a good job). Nevertheless I don't insist to same the name "half". Calling it "Prentos promotee" might be another way. Nicolas.

A Pronkin is paradoxical too, but you wouldn't want to call that a 'homecoming Schnoebelen', would you?

Of course not, as it has already a name ! (and incidentally a Pronkin is not captured in general). I just think that "a promoted piece captured by an officer" is an important enough concept to deserve a special simpler name. What about my last proposal "Prentos promotee" ? Nicolas.

Is the point that it's captured by an officer, or just that the capture does not leave an obvious trace in the pawn structure?

The point is that "invisible capture" is not a clear concept. One may say that no capture is really invisible as it can be logically deduced (in a sound proof game). Nicolas.

Frankly both of these seem dire to me :-). The abuse of the word "Pure" is the direst. What is pure about *adding* an additional constraint to a C-F capture? Pure = simple = unadorned. "Half" is nearly as bad - I object to the false arithemeticity. If I may contrast the term "half-pin": there is in this term some reason why it is "half" rather than a "third". Please can someone who is not famous already compose some problems with this theme, and then we can name the pattern after them :-) Love, Andrew.

It's an implied property of a S-promotion, not a property itself.

Many of the disussed terms are related to homesquares and promotion squares. This recalls me my first year in the Chemical Engineering faculty (70s!). It was the time when the terminology for organic chemistry (a nightmare) started to be "rational", i.e., names that describe its subject in a logical way destinated to replace the old empirical names. The propossal that Andrey Frolkin and I presented in our article "There is no place like home" (using homesquares in SPGs), Strategems oct 2007, shows a clear analogy with this; the difference is that we did not pretended to replace the existing names (for instance, Pronkin) but to stablish a theorical base that contain all this tricks logically connected to few basic concepts. * Homebase (hb): a piece standing on a square that corresponds to this piece TYPE in the initial array. * Homecircuit (hc): a piece standing on its TRUE homesquare So, what's a hb-non-hc piece?: An impostor. A piece pretending to be the true square's owner (Pronkin, sibling). And what's a hc-non-hb piece?: A "Pawn/officer Rundlauf", from homesquare to promotion and back to homesquare. In this case the homesquare generates a "meta-homesquare" for any piece of the same type as the promoted one (say, if the f2 pawn promotes to a knight and the b1 knight is standing on f2, then it's a sort of "meta-impostor"; we named it as e-metasibling. Complementary, the promotion squares are meta-homesquares. * Meta-homebase (meta-hb): a piece standing on the promotion square of a piece of the same type and color. * Meta-homecircuit (meta-hc): a piece standing on its promotion square. So, what's a meta-(hb-non-hc)?: an Antipronkin In addition, there is the Stationary condition (stationary is a piece that did not move; meta-stationary is a piece that did not move after promotion) and the "phantom" condition (a piece captured on its thematic square). What's a meta-stationary phantom?: a Schnoebelen What's a meta-(hc-non stationary) piece? a Gianni Donatti 50th JT trick. And so on.
