That looks like tons of fun, though for me it's a little hard to believe that two 1800 players would follow 23 moves of theory like that.  It's always nice to win games "at home," so to speak.


Oh, sorry, I wasn't very clear here. It was a correspondence game. I mentioned that some 20 posts ago but it wasn't clear from this post. No chance I would remember 23 moves of theory in a relatively unimportant variation. I'm not sure why my opponent chose this variation. I thought he had something in specific in mind/preparation but appearently that wasn't the case. Just wanted to give give an example of the depth of the book's analysis and maybe revive this thread. The publication didn't start a big discussion really ...

Since this thread has not been very active lately, I would like to share as an example a game which i played using Cohen's book. It is however not in the Petrov, but the Spanish 4 Knights which can be reached in Cohens book via transposition. I'm not very familiar with the Spanish 4 Knights, however, I felt that the coverage in the book was of a great depth and a good guidance. I commented the game very lightly, but I made sure to point out at which point I left his bookknowledge.

There do seem to be quite a few recent books on lines that I had considered my own special secret.

The Petrov just doesn't have much ink devoted to it. I still rather doubt many people will rush to play the Petrov, but there is a definite trend of strong analysts writing books on openings that had previously been all but ignored.


I think about taking up the petroff as my surprise weapon, right now I play sicilian paulsen/taimanov:

- after 1.e4 e5 - how often do you get the chance to play the petroff?  (2.f4, 2.Bc4 a.s.o)?
- which lines prefer the 2000-2400 elo players? 
- maybe this sounds a bit weird, but how do you usually win in the petroff or do you use it as a draw weapon against stronger players only?


I would love to hear the answer to those questions as well. No real interest in the topic everyone  Embarrassed

Dennis Monokroussos just posted a review of the book on his blog.

http://www.thechessmind.net/blog/2014/1/1/a-review-of-cohens-_a-vigorous-chess-o...


Thank for sharing this. I have a question regarding this part of the review:

" [...] Cohen recommends the declined line 1.e4 e5 2.f4 Bc5 3.Nf3 d6 4.Nc3 Nf6 5.Bc4 Nc6 6.d3 Bg4 7.Na4 0-0 8.Nxc5 dxc5 9.0-0 Qd6. After 10.Qd2 Bxf3 11.gxf3 exf4 12.Qxf4 Marin gave 12…Ne5, but Cohen suggests the novelty 12…Nd4 instead."

Since I never played the king's gambit, I have no clue what is going on here really. I wonder if black has no impovements up to this point in the KGD. Why is black surrendering the center with 11...exf4. Is 12. f5 such a terrible threat here? The computer seems to love 11...Nd7 here, with the possiblity of retaken with the d7 knight in case of 12. fxe5 and the idea 12. f5 Nb6. Black's kingside seems to become a little shaky in the later case but it doesn't look so scary. But maybe I'm too much computer influenced (sloughterized so to say) here and this just rubbish. Any thoughts?

Thoughts anyone thus far? Has been out a while now.
Happy with lines chosen? Depth and accuracy (in your humble view) of analysis?

And, @Mods, perhaps this and earlier posts could be split to a new thread: 'Vigorous Petrov book by Cohen' or something.

Cheers,

I support the new thread idea!
I got the book since around christmas. I started three correspondence games without any prior knowledge. In one my opponent resigned during the opening phase (no clue why) so I can't say much about it. The second was the Glek four knight's (see earlier in the thread). Which is obviously not very cutting edge. I got comfortable equality.
The last one is ongoing in the line 1. e4 e5 2. Nf3 Nf6 3. d4 Nxe4 4. dxe4 which is not very critical either. The game got me to move 11 when my opponent played a move that has been played otb once and was reached 9 times in total. I would consider this a reasonable depth. So I would say that my impression is better than what the review suggests.
I have no idea how opening preparation of players >2200 is but I am pretty sure that this book is more than sufficient for anyone below that level. I have seen players 2000+ starting to think on move 4 in a main line ...
I have to agree with the author of the review that the modern italian game is not very detailed though. I haven't gone through it in detail, but having played this system with white myself I can hardly believe that it can be disproved on two pages or so. On the other hand the recommendations of Cohen at least don't let you run into very sharp variations without sufficient explanations.

These are just a few (very subjective) impressions I had.

Thanks to everyone pointing out weak spots in the analysis. I will have a look at them Smiley

The older, the better - over 2200 and still rising.

How does Cohen's new book compare to Sakaev's?

Thanks.

I am ambivalent about this new interest in the Petrov. I completely agree that it is undervalued as a winning effort below the grandmaster level, as Dennis Monokroussos states. But I don't want everyone to know this! Chess is hard enough without players coming along and shining their analytic lights on lines that are traditionally ignored.

I may have to go find new lines to play. Angry

just saying that in the mentioned 15...Bd6 line 16.c4 Qe4 17.Be3 Rad8 18.c5 Be7 19.Qb3 looks interesting for white too

Finally received my copy yesterday. Of course this implies that I haven't really gone into any details yet, but the breadth of the coverage and the way it is present looks appealing.
I like that the author doesn't shy away to contradict other chess writers and adds a fair deal of personal experience and opinions. If the analysis keeps up with what the rest of the book promises this is a great effort. Has by chance someone who knows his stuff about the Petrov checked the analysis of a very critical line?
