Isn't there a survey in NIC YB 102 on the ...d4 line. I am way too busy now to check.


Yes, there is, but Tibor doesn't consider the best move 4.e3.

I have the book, and it seems as if 1. Nf3 d5 2. c4 d4 one must play 3. b4. But this line seems very crazy, so if one knows that the opponent will play 2...d4, would it be better to invert the sequence, i.e. 1. c4, 2. Nf3, and play 1. Nf3, 2. c4 against those who do not play 2...d4, for example if one knows that the opponent usually plays Slav or Semi-Slav?

1.c4 can be met by 1...e5 - that's why all the Reti players prefer 1.Nf3 first.  Wink


Unless one knows that the opponent never plays 1...e5 whilst preparing, at least looking at games in a database.


That's certainly an alternative and my decision on whether to play 1.Nf3 or 1.c4 (if I'm going to play an English) depends a lot on how I think the opponent will respond. However I don't think White should fear 2...d4 too much - it's a good move but this 3.b4 line seems easier for White to play in practice even if (as I suspect) it should be equal with best play.

You're not at all forced to play 3 b4 there. The traditional main line of 3 g3 is a lot more 'rational'. Probably also consequently less dangerous for both sides. Or 3 e3 of course.

Where to draw the line?

If lines are already well known it's also OK to give them here. There is no copyright on common knowledge. And it's possible to write something like "Author X thinks the game Y - Z critical".
  

The book had the effect good books usually have: it made the stupids more stupid, the intelligent more intelligent and the other thousands of readers remained unchanged.

I was wondering about copyright considerations, I don't want to feel like a pirate. Where to draw the line?  Surely if I write up a whole chapter of analysis, that would be tut-tut. Just writing that he offers 3 g3, 3 e3 and 3 b4 vs 2 c4 d4 is surely OK. Answering TN's question in detail would be in between. Has this been discussed before? Sorry for the off-topic.


Its a delicate line - its OK to give what his main options are but not usually OK to give a ream of nitty gritty analysis. That said we have frequently given the odd snippets/suggestions here, which I think the publishers dont mind because its kind of a teaser for people to buy the book.

Dunno, but it seems to me Vass and TN have the balance about right.

Against 6.Qb3 I'd play 6...e4 7.Nd4 a5 8.Nc3 f5. Does Delchev have an improvement on move 8?

I just returned from Plovdiv where I bought the new Delchev's book from the chess shop at the European Championship (as well as many other new books from other authors). I didn't have enough time to read it yet. Now I see on page 44 he gives a long variation starting with 9.Ne6 Qe7 and then 10.Qa4+ which seems to be his analysis move (unlike the continuation in the Gabriel-Korchnoi game in 1999 i.e. 10.Nxf8). I would not give all the variation here because of copyright issues, but after his 15th move in the main line of his analysis he concludes "...and the e4-pawn should perish after g3, Bg2".
Btw, what 'recent practice' do you mean? I've found only two games in my Mega Database 2012 - the last one played in 2001.  Shocked (Though I admit I'm too lazy to check my correspondence chess databases..)
Meanwhile, I don't have to be Delchev to express my opinion that even the temporary pawn sacrifice via 9.b5!? (my mark) gives white more than a good compensation after say 9...Bxc5 10.Ne6 Qe7 11.Nxc5 Qxc5 12.Ba3...and so on... In short, 5...d3?! (Delchev's mark) can bring you only troubles.  Wink
Edit: I saw a correspondence game from 2010 where 10.Qa4 Kf7 11.Nxf8 was played so 10.Qa4 is not Delchev's move, obviously.  Cool


I'm not completely sure about 10.Qa4 being better for White, but I don't want to 'steal' all of Delchev's lines. 9.b5 looks good for White regardless.

My question was to determine whether I should buy the book - the book passed my little test.  Wink

Out of interest, does Delchev think White has an edge after 1.Nf3 d5 2.c4 d4 3.b4 f6 4.e3 e5 5.c5 d3? I've thought for a while that only Black can play for an advantage after this move and recent practice hasn't changed my opinion.

Delchev doesn't consider this dangerous. It is a sideline in the book. I know his line starts with 6 Qb3. I can give you the whole line later today. Don't expect any informed assessment on my half, but I can parrot the lines on the forums. Smiley
