Some people may have noticed I am trying to translate an old Go book. Every so often I find the copy I am working from has some mistakes - nothing new there! I would like to ask for help solving one of the harder ones. As you can see, we have 3 figures in a row which are essentially the same. I have decided that the first figure is probably correct, but the next 2 are wrong.

The essential translation is then:

Starting Figure 4.2.1 (actual game)
Black 15: should be played at d , see Figure 4.2.2

Broken Figure 4.2.2 (variation)
After black 1, white connects with 2
then black 3, white 4, and black 5 continues the attack
(if white "a", black "b")

After black 1 white could play "C" - see Figure 4.2.3

Broken Figure 4.2.3 (variation)
Following the exchange of 1 and 2 here, black could continue with 3, strengthening his moyo above.
Now white must play "a" or "b", then black "c" (and eventually "d")

You might have some luck if someone recognizes the source of the diagrams as coming from another book.

It sounds like the following two diagrams start with the suggestion for :b15: at d as :b1:, and should have diagrams for a couple of follow-ups by white. The last diagram seems, based on the text, to possibly begin a couple moves into a variation of the second diagram. I'm not sure what moyo they are speaking of, however. Is there a full-board position or an explanation of how the starting position occurred earlier? It seems vaguely like a 3-4 3 space low pincer joseki, but I don't recognize it.

Incidentally, is this in Romanian?

These diagrams will not appear in any other book, they are games played in Romanian tournaments, so yes indeed, the language is Romanian. Starting from the assumption that figure 4.2.1 is correct, I would like to guess what the next 2 diagrams should really be. (figures 4.2.2 & 4.2.3). These next 2 diagrams are variations on the game.
We know that Black 1 in figure 4.2.2 is the marked point "d" in figure 4.2.1.

Maybe something vaguely like these? I'm not sure.

That line is a reasonable looking starting point. Some ideas for variations are to play 3 one space higher, or to play 4 as an attachment to 3.
