Pogosyants study happening in OTB game


As I read through the biography of the bygone IM Svein Johannessen, I discovered that a Pogosyants study had appeared in a game in the Olympiad, even with a study-like introduction:

Ernest Pogosyants
Prapor Junosti 1976
(= 3+1 )


1.Kd6+ Kc8 2.Bb7+! Kxb7 3.Kd7

Johannessen - Rivera
Varna Olympiad 1962
(= 6+5 )


1.b6+! axb6 2.a7 Kb7 3.c6+ Kxa7 4.c7, and Black resigned instead of continuing with 4...Kb7 5.Kd6+ Kc8 6.Bb7+! Kxb7 7.Kd7.

Technically, this means that Pogosyants's study is anticipated by the Johannessen-Rivera game. But I doubt he was aware of this game, so instead of grumbling about anticipations, I will pretend that it happened the other way around, and look at it as a rare case of a study happening in an OTB game.

Sorry, but while there surely is an optical similarity, the motivation of Pogo's move is different. If the bishop was removed from the board, Black would also have to play Kb7 by zugzwang, so 2.Bb7+ is a correction move.
(2.B~ wins; 2.Ba8/Bc6/Bd5/Be4/Bf3/Bg2? stalemates; 2.Bb7+! wins)
