Hi,

Is there any book containing good analysis of this opening? Jeroen's book seems to be not up to date...
Is it playable at computer chess ?

Thanks :)

Chess openings for white explained. (if u want to know how to meet it)

It's a tough nut to crack, so i bet it is playable.

No. Its not a tough nut to crack. White gains advantage. Its similar to that Chigorin defence in set up.

prove it. play a few moves past Qd6.
Parent - - By Master Om (Bronze) Date 2010-02-18 13:32
Why not. Actualy an analysis was published in NIC regarding few critical lines and refuting the b5 line which was thought to be the main line.

Do I smell a omprakash Vs. Werewolf game? :)

Ha ha Ha

Do you know which edition of NIC?  I would like to find it and go over the analysis.

It is something between 85-90

Nice game, but black's position after the opening doesn't look too inspiring to me.
I meant computer books, not paper books btw :) Maybe one of those participating in those book contests ?
Parent - - By Nelson Hernandez (Gold) Date 2010-02-19 12:23
Harvey, why would you assume white will play 9.Be2?  That is the worst move in my book.  9.c5 Qd8 10.Bc4 O-O 11.O-O Bg4 12.Be3 and now either Na6 or b5 are historically >60% drawn and black's best chances to hold, though both lines could develop into a clear advantage for white.

We were fairly certain Rybka would play this line as they would not have done any special prep and would play the line that was in the commercial book by Jeroen which they did.
Parent - By Master Om (Bronze) Date 2010-02-19 14:21
Aha !! So you used  a good IDeA !!!
Parent - By Carl Bicknell (*****) Date 2010-02-21 22:47
yep nice game, Qd6 isn't trivial that's for sure.

As white I have tried (in my human games) 4.g3 with the intention of going in for this line:

1. e4 d5 2. exd5 Qxd5 3. Nc3 Qd6 4. g3 {0} Nf6 5. Bg2 c6 6.
d4 Bf5 7. Nf3 e6 8. O-O Be7 9. a3! since now black cannot develop with Nd7 on account of Bf4. Anyway, black doesn't seem to be in too much trouble.

I recommend you the following DVD:

http://www.chessvideoclub.com/chessvideoclub/chessvideo/vol68-scandinavian-weapon-black-download-p-61.html

All analyses and lines are Rybka-proved.
Parent - By JDrysdale (***) Date 2010-02-19 16:49
great post, I think I am going to get the book H. linked, and this DVD.
Parent - By JDrysdale (***) Date 2010-02-19 17:15
Amazon.com product summary for the DVD:  "...To sum it up, the 3...Qd6 Scandinavain is cheating at chess, because with a little amount of preparation you will get a high return..."

This is line what you must to know! Nothing more.

1. e4 d5 2. exd5 Qxd5 3. Nc3 Qd6 4. d4 g6 5. Nf3 Nf6 6. Nb5 Qb6 7. c4 c6 8. Nc3
Bg7 9. c5 Qc7 10. Bc4 b6!?
Parent - By Rubinus (**) Date 2010-02-21 22:57
Concept 6.g3, 7.Bg2,8.0-0 and Nb5 etc.
Parent - By NATIONAL12 (Gold) Date 2010-02-22 00:09
in your line,i dont see much wrong with the simple.9.h3 0-0 10.Be2 Rd8 11.0-0 it may not be in the spirit of the game,but appears fine for white.

IMO Qa5 is best over Qd6. I win far more games with Qa5 then with Qd6. Funny thing is I have study material on Qd6 and not much on Qa5 (I am on my own a few moves after Qa5 and depend on my natural skill more).

I'm a Qa5 man too, but I'm open to investigating Qd6 further as a surprise alternative.
