Brilliant, Poghosyan, thanks.

Quite hard to construct a sensible last few moves leading to the Reti position, actually.

On this very complicated subject there is an interesting article of grandmaster for chess composition S. Tkachenko in ChessPro – Passions on the idea of Reti -http://chesspro.ru/_events/2011/tkachenko3_kart.html). ;

Reti admitted himself that the idea of the study was conceived from a non published game of Schlechter («Ostrauer Morgenzeitung und Handelsblatt» from  December 4, 1921). The game was played in 1893. 

According to A. Mandler who published the collection of complete studies of Reti in 1931 the study of Reti was composed in summer 1921 and Reti showed it in his public lectures and meetings. Abrahmas refers in his book obviously to an anonymous game (allegedly played in Berlin 1921) which was published in «Teplitz-Schonaure Anzeiger», October 30, 1921. S. Tkachenko believes that there was no such game in Berlin at all and that the author of the publication was obviously familiar with the study of Reti on a lecture grandmaster! 

I was recently reading 'Technique in Chess' by Gerald Abrahams, and two things struck me.

First, he says that the famous Reti study (W Kh8 Pc6, B Ka6 Ph5) arose in a game in Berlin in 1921, and that Reti noticed the position was drawn, rather than inventing the position, a la Saavedra.

Is this story true? I'd never heard it before, but perhaps everyone knew it except me.

Second, he says that the book arose out of a series of talks he gave in the early sixties on radio. Yeesh. It was a different world when the BBC was broadcasting  talks on rook endgames. Anyone old enough to remember these/ever heard them?!
