Unsourced Quote

Garry Kasparov, My Great Predecessors, Part 1 offers a quote that he attributes to Lasker. He does not indicate whether Emanuel or Edward. Nor does he indicate the text where the quote appears. The brief reference list in Part V lists nothing by either Lasker. Two weeks ago I noted criticism of Kasparov's My Great Predecessors for poor documentation in "Plagiarism and Related Crimes".

The quote comes at the end of Kasparov’s brief discussion of Gioachino Greco, where he presents four games with light annotations to the fourth.

The masters of that time found a sound and fruitful plan: disregarding pawns, achieve a rapid development of the pieces for a swift attack on the enemy king. To oppose this, a counter-plan was worked out: develop the pieces in solid positions, accept the sacrifices and then win thanks to material superiority. The masters of the first type found and carried out brilliant combinations, whereas the second type discovered the Giuoco Piano, the fianchetto and the Sicilian Defense. (12)

It is an interesting narrative that would benefit from some illustrative examples.

I would like to locate the original source of this quote. Was it in an article or a book? I do not recall seeing this sort of historical discussion by Emanuel Lasker in Common Sense in Chess nor in Lasker’s Manual of Chess, although the assertion does seem preliminary to Lasker’s purpose in the latter to explicate and build upon ideas of positional play credited to William Steinitz.

Can anyone help?

Edit:

Eight hours after posting I found a version of the quote. No doubt, Kasparov is working from a Russian translation of Lasker’s original German. I am working from Lasker’s English edition, which he wrote because he thought a translation would be too literal to remain faithful. The quote derives from Lasker’s Manual of Chess (1947). I am using the 1960 Dover paperback edition.

The modern history of the art of planning began at the time of the Renaissance in Italy. The Italian Masters of that period conceived a fertile and sound plan: to get the pieces rapidly into play, to leave the pawns out of consideration and to institute a sudden and vehement attack against the king. The counter-play on its part did not fail in evolving an antagonistic plan: to develop the pieces and post them at safe points, to accept the sacrifices and to exchange the threatening pieces of the opponent, add to win by superiority in material force. The masters of the attack invented the brilliant combinations which began by cramping the king and proceeded to sacrifices in order to gain time and space for a direct assault on the king. The masters of the defense invented the systematic exchange of pieces which decreases the vigour of the hostile onslaught and at last breaks it. The masters of the fierce attack, discovered the Gambits, those of the defense the Giuoco Piano, the Fianchetti Openings, and the Sicilian Defense. (179-180)

Even accounting for differences in translation, it appears that Kasparov edited the passage slightly.
