I see that the same question (when/where exactly did Breyer suggest the retreat Nc6-b8 in the Ruy Lopez?) had been discussed at some length here. Since Hans Müller remains the main source for crediting Breyer with the invention of Nc6-b8, here is the original text from Müller's comment on Milic - Spassky, Lyon 1955, in Schach-Echo 1955, p. 247:

Paddy and DMel, thanks (again) for the explanation.

Nope, you are right that maestro is singular, the plural being maestri. But this expression in particular "qualche altro maestro" strangely translates as "some other masters".

Maybe I can sneak in over the Canadian border. Once there was someone detained in a US prison, and for some reason he wasn't permitted to get a free issue of Kaissiber.

"According to Marshall and other masters this is the strongest response to the kingside fianchetto, as they consider early piece activity to be more important than pawn structure.
Conversely, Alekhine thinks that blocking the c pawn with such a knight move makes c3-d4-e3 impossible, and he considers such a formation to be the ideal one against the kingside fianchetto.  Valuable opinions!" (the last sentence is actually a bit bizarre but I suppose he means that both opinions sound reasonable to him)

Similarly, the description 150 Attack is now well established in British chess circles. To what extent is it known internationally, where the 150 reference would be obscure?

Hmm, the plan of capturing d4xc5 followed by Nf3-d2-b3 was played in Yates-Capablanca, New York 1924, but with Capa playing 6 h3 instead of 6 Be2. 

After 1 d4 Nf6 2 Nf3 g6, the move 3 Nc3 was played three times in that tournament, although it came in for criticism by Alekhine in the tournament book. The first to play 3 Nc3 in the New York event was Ed. Lasker, in Round 1 against Maroczy, who allowed transposition to what we now call the Pirc.

In Die Hypermoderne Schachpartie, Tartakower describes 3 Nc3 as "Marshalls Zug", although Tartakower himself had played 1 d4 Nf6 2 Nf3 g6 3 Nc3 d5 4 Bf4 against V. Wahltuch at London 1922.

I mentioned in an earlier thread that the first systematic treatment of the line 1 d4 Nf6 2 Nf3 g6 3 Nc3 d5 4 Bf4 was possibly Graham Burgess's 6-page article in the British Chess Magazine of August 1991. He entitled it "The Hebden/Hodgson Attack" but quoted as earlier pioneers Capablanca, Niaz Murshed, Zsusza Polgar and Ian Rogers. 

However a rapid check in a good database will soon establish that it was tried by a good many masters prior to its rise to fame in the late 1980s.

By the way it is also apparent from "The Soviet Chess Conveyor" that Mikhail Shereshevsky was also playing and teaching this opening in the late 1970s.
