I guess that many voters prefer books offering much value for the money. In this respect, a 600-page work may have an advantage. But I am disappointed that a writer of chess books has a similar point of view. BPaulsen may change his opinion, once he sees his own work misquoted.
John Shaw's book
The King's Gambit often avoids to quote his sources, or doesn't quote properly - often it is hard to distinguish between Shaw's ideas and foreign ideas. This could be sloppiness, if it were not so widespread in his book. Even more irritating are the cases where Shaw misrepresents evaluations of other authors. Let's see an example: a situation covered by Shaw on p. 429 in his work, bottom right, diagram after 20...a6. Shaw writes:
Quote: Bücker evaluates this position as unclear, but it seems to me that White's chances are higher after the following virtually forced continuation. 21. Ba4! b5 22.Bxh8! (not 22.Bb3? Nc6) 22...bxa4 23.Bf6 Nc6 24.Qxa4. Material is close to equal, but White has the upper hand thanks to his strong rooks and safer king.
My original analysis, published here on chesspub, can be found as reply #15 in this thread:

Even stronger:
14.dxc6 (instead of 14.e6)
14...dxc6 15.Qd4 Nbd5 16.Nxd5 cxd5 17.Bb5+ (17.e6!? Bg7 18.Bb5+ Kf8 19.Qb4 a6 20.Bd7 is also dangerous)
17...Kf7 18.e6+ Kg8 19.Rhe1 seems to favour White.
Black can free his position:
19...Bxe6! 20.Be5 a6 21.Ba4 b5 22.Bxh8 (22.Bb3? Nc6)
22...Nc6 23.Qc3 Qh6+ 24.Kb1 d4! when he may survive. But "comfortable" wouldn't be my word to describe Black's life in this variation. [...]
So, Shaw is wrong to claim that I evaluated 20...a6 as unclear. I had thought that Black may "survive".
Further, "his" moves 21. Ba4! b5 22. Bxh8! do not refute my opinion, as they were already part of my analysis.
Finally, my 22...Nc6! seems more precise than 22...bxa4.

White has a small plus, but to say that "White has the upper hand" would seem overoptimistic.
Pages 47-90 in Shaw's book cover what he calls the "Flude Line". This is another topic with a "history" on chesspub.

However, it is a pity that John Shaw is getting almost every detail wrong. After 9. Nc3 Qe7 10.0-0 Bxe5 he ascribes the continuation 11.Nb5 ("!!" Shaw) to the Australian David Flude. Mr. Flude himself had honestly attributed the move to Keres. John Shaw seems puzzled ("one can rarely be totally sure who saw a move first"), but he might just have looked into Kaissiber #33, which discussed 11. Nb5 in detail, saying "
11.Nb5! (Nei 1980)". Ivo Nei was the man who edited the "Keres" after Keres' death.
The position after 11...0-0 12.dxe5 a6 was regarded as good for Black by Nei, Estrin, Glaskow, Gallagher and a few others. David Flude's important contribution, published 2004 on chesspub, was 13.Nd4!. All these facts had been in Kaissiber #33. John Shaw's decision to name 9.Nc3 "Flude Line" is a bit strange. At the very least I'd expect that Shaw would credit my analyses properly. I had studied the line in articles for chesscafe.com, and Kaissiber #33. John Shaw has filled these chapters with many of my findings, and he does not think it is necessary to give the precise sources? The bibliography of
King's Gambit doesn't even list Kaissiber, but it does mention another magazine which I never heard of: Kassiber.
Let's close for today with p. 114, line 5/6 from above. Shaw writes: "On the ChessPublishing Forum it was claimed:
15.Bxf4 was unclear, but in this case I have to disagree..." Why doesn't Shaw say who had proposed the move / made the evaluation? By the way, I can't find that chesspub thread to which Shaw is refering. This kind of quotation isn't helpful for other authors who want to check the source in more detail.
