I have just bought the Marin book, and I have to say I am surprised and a little bit disappointed!

The way he has arranged the material is very strange and he gives too much space to lines that he rejects, and bad moves, in an attempt to show what one should avoid. For instance, in the Evans Gambit chapter he discusses 3 moves in some depth, and then devotes only two paragraphs to his favoured 4th move! There then follows an ugly ECO style section which deals solely with this 4th move (7...Nge7). I would much have preferred to see the space given over to instructive games involving this move, with the alternatives consigned to small notes.
Still, there is obviously a lot of useful information to be gleaned from this, and I shall be bringing it with me to future tournaments!
Regarding 'false friends' I have to admit to employing more and more of these since moving to France a few decades ago, and I even sometimes find myself completely forgetting the English equivalent of a French word!
I do most of the editing on ChessPublishing and I can say that the 'House Style' is to allow any terms (or even misspelt words) if they sound sufficiently 'chessic', i.e. if their meaning would be completely understood by a chess player, or they are in fairly common use amongst chess players.
