This article shows nine examples. Few days after both magazynes had been delivered I'll make the article available trough this RML/Retrocorner.

The proofgame is unsound, which was informed to the tourney director during confirmation time in spring 2007. At the same time was informed the correction by having black's last move to be 25. - Lg6 instead of 25. - Dg4 (corresponding diagram change bDg4 to g3 and bLh5 to g6).

Many thanks to Nicolas Dupont, Michel Caillaud and Jorge Lois for their support. Preparing this I felt as to be in the time machine. All started during the 80s (I was so far from all of this that time!). I can Imagine Pronkin, Frolkin, Heinonen, Caillaud, etc, composing these PGs while listening the Bee Gees. Any further collaboration very wellcome. Best, Roberto --------------------------------------------------------------------------------- Many typical PG?s tricks are related to home and promotion squares. For instance, CF = Cerianni-Frolkin PR = Pronkin AP = Anti- Pronkin SC = Schnoenbelen SI = Sibling GD = Gianni Donati 50th (a switchback from and to promotion square) PC = Pawn circuit (a pawn promotes and get back to its homesquare) SW = Switchback (from and to homesquare) The compositional targets based on these have been largely increased during the last years in terms of duplication, eco, etc. We are focussing here in a further well defined and challenging task: let?s X(A) be a double rendition of the ?x? trick performed by two different pieces of type A, and Y(B) a double rendition of the ?y? trick performed by two different pieces of type B. Then, a PG showing both X(A) and Y(B) can be characterized as, X(A) vs Y(B): each side performs one double trick X(A) & Y(B): both double tricks are performed by the same side X(A) mx Y(B): mix, each side performs one single ?x? trick and one single ?y? trick Kostas Prentos suggested to name these as ?PGs of the Future? (TFPG) in analogy to the Chris Feather's helpmates of the future (there are two phases in these helpmates showing a couple of well defined strategies). Most of such PGs are of high quality andcertainly very challenging to compose. Let?s see an example, TFPG GD(N) vs SW(N) Satoshi Hashimoto / 8073 Feenschach 135 01-05/2000 1. Preis ----------------------------------------------------------------------------------------------------- 1n2krn1/p1p2p1p/bq2p1rb/3p4/8/8/PP1PP1PP/RNBQKBNR 1. c4 d5 2. c5 Dd6 3. c6 Sd7 4. cxb7 Db6 b8=S La6 6. Sc6 Td8 7. Sb8 Sxb8 8. f4 Td6 9. f5 Tg6 10. f6 e6 11. fxg7 Sf6 12. g8=S Lh6 13. Se7 Tf8 14. Sg8 Sxg8 ---------------------------------------------------------------------------------------------------- This a good example to discuss the trick?s definition. After 7.SB8 and 14.Sg8 both knights performed a GD trick but since they were captured thereafter they performed also a particular case of CF in the Kostas Prentos? JT style (a promoted piece is captured by an officer). I?m proposing here a characterization of this and other traditional PGs? aspects in order to properly differentiate ?similar? problems. ?PHANTOM?: the piece is captured on the thematic square leaving no obvious traces of that capture. This applies to all the tricks and is straightforward for a Prentos? capture but there is another special case when dealing with CF: cross captures by pawns are ?phantom? too (see the subtle difference between the Aschwanden and Dupont?s CF(B) & AP(B) problems). I?ll mark with ?ph-? the phantom tricks. ?SUPER FUTURE?: a nice concept suggested by Michel.. TFPG is ?2? plus ?2?. What about ?3? plus ?3? or ?2? plus ?2? plus ?2?, etc? We have some examples in the list. ?BONUS MARKS?: we have many examples showing ?steps towards the super-future?, for instance a one side triple Bishop CF. I use + as a ?bonus? mark, indicating this case as CF(B+). In other cases, there is an additional piece of a different type showing the same trick. In this case I use the bonus mark outside the brackets (for instance, CF(B)+ means that another piece of a different type than bishop makes a CF trick). ?HOME ASPECTS?: a) hb, as homebase b) hc, all the side?s pieces are on their homesquares (Homecircuit, from the Osorio & Frolkin ?s article ?There is no place like home?, Strategems oct 2007); see Per Olin?s PG to realise the difference with hb c) off-, preceding hb or hc, means that this condition applies to officers only. ?NON-STANDARD MATERIAL?: visible promoted force on the board, marked as ?non-std mtl?. THE DIAGONAL CASES (in analogy to a matrix representation). These would be the particular cases where: a) both double tricks are performed by pieces of the same type (?type? diagonal) b) both tricks are of the same type (?trick? diagonal) c) both the tricks and the pieces are of the same type (diagonal-diagonal). I?m presenting the list trying to keep some order (this deal is an N dimensional hell), starting with the diagonal cases; diagrams and positions are included at the end (I left the SW/SW cases for the next updating; they will surely deserve further discussions).

The point is that when CF is easy (eg for knights) then PR is complicated, and vice-versa. The simplest one is probably when A=Rook, but even in that case this is unclear, at least to my eyes, how to construct it. Best wishes, Nicolas.

Reinforcing the Nicolas question on the PR(R) & CF(R), what about the equivalent "vs" case?
