'Time', as he understands it. 'Development', as he defines it. You'll rue your words, MNb, when Sloughter refines his unified theory of chess.

Time to slam sloughter again.

1. You don't listen to good, well-meant advise.
2. So you don't do any research (books etc.) before posting a few moves.
3. You don't store the information of this thread.
4. So you forget the game I posted.
5. You confuse intuition with silicon judgment.
6. You refer to Steinitz repeatedly but only when it suits you.
7. So you ignore Steinitz' judgment on the initial position: equal.
8. You use big words like internal harmony of chess but don't understand them.
9. So you are looking for a refutation of three moves by Black that fulfill all sound principles of opening play (1...e5; 2...Nc6; and 3...Nf6).
10. As a result you make yourself ridiculous.

If you display these qualities in your book too it's a crime against natural environment - you'd rather have let stand all those trees were they stood.

I am not gonna feed you like a chess baby. Take a look in a random book on the Two Knighs and you will find out how Black rather should play your line. Reread this thread and you will find the same. In the mean time I cannot help thinking of the old Dutch proverb: Spuit elf geeft ook modder. Yes, that's an insult.
  

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.

In the internal harmony of chess, the Berliner Variation gives White too much of an advantage, 8...Ne6, too little. Using intuitive iteration, the process of starting over, here is my latest try against 8...Ne6---4.Ng5 d5 5.exd5 Nd4 6.c3 b5 7.Bf1 Nxd5 8.Ne4 Ne6 9.Bxb5ch Bd7 10.Bxd7ch! Qxd7 11.O-O! Ndf4 12.d4! f5 +/- (according to Fritz 8)MNb wrote on 01/30/09 at 00:55:28:

I don't like Black's position after 12.dxe5 Ne3 etcetera, even though Black has done quite well in practice. So I prefer 10...exd4 and a fun line is 11.Bc6 Nf4 12.Bxa8 Ba6. If White plays 10.0-0 instead there is again 10...exd4.
 


Indeend, I couldn't find anything for White after 10.Qf3 exd4! 11.Bc6 Nf4 etc.

But I switched back with 10.0-0 because I don't see any drawback of playing 10.0-0 withe my previous idea. And the advantage now after 10..exd4 is that White's king doesn't stay in the center. 

So :
10.0-0! Fb7 11.Qf3 Rb8 12.dxe5 is what I wanted.
10.0-0! Rb8 11.Bc6 exd4 12.d3 Qf5 (or 12..Nf4 13.Na3!) 13.Re1 seems better for White (but Black may have attacking chances in the long run in White's king)
10.0-0! exd4 11.Bc6 Rb8 12.d3 and see my previous line.
10.0-0! Nf4 11.Bc6 Rb8 12.d3 (12.dxe5!? Rb6 13.Bf3 Nd3 14.Be4 Rh6 and improvments for White are probably possible over the game Essegern-Sobeck 0-1, corr 1974) 12..Rb8 (12..exd4 13.Na3!) 13.Be4 where White seems to be better again.

Any improvment/other evaluation somewhere? MNb Iam interested by your toughts because you seemed to advocate 10..exd4 after 10.0-0 too.

The Two Knights Tango must be stopped. White has a simple reply that shuts down the dance. 4.Ng5 d5 5.exd5 Nd4 6.c3 b5 7.Bf1 Nxd5 8.Ne4 Ne6 9.Bxb5ch Bd7 10.Be2! Ndf4 11.O-O Nxe2ch 12.Nxe2 Nf4 13.Qf3+/-sloughter wrote on 01/11/09 at 03:20:21:
I am convinced with your analysis that White gains nothing with 8.Ne4 because the Two Knights' Tango all are developing moves as I define development. No wonder 8...Ne6 works so well! However, I am going to check with GM Alburt about 7.cxd4 bxc4 8.dxe5 & get his take on the positions.

Amazingly enough, in the Steinitz variation, 4.Ng5 d5 5.exd5 Na5 6.Bb5ch c6 7.dxc6 bxc6 8.Be2 h6 9.Nh3?! Bd6 10.d3 Qc7 11.Ng1! O-O, Black has nothing unless someone can find a way for Black to get in e4 with advantage. 

White has a Universal Position, the most difficult kind of position to attack. According to Kasparov (If you want a textbook case of what a Universal position is, just check out the World Championship games between Kasparov and Short with Garry on the Black side of the Sicilian.) it is necessary to advance your own pawns to break up a pristine pawn position.

The King's Indian Saemisch is probably favorable to White, because it is, to the best of my knowledge, the only major opening by White where White stays in Universal mode in the opening. Has anyone tried the following strategy c4/d4/Nc3/e4/f3/g3/Bg2/Nh3/Nf2 & then just push the Queenside pawns, rearrange your pieces behind the pawn wall and then break through? 

In the Steinitz variation, a huge lead in development dissipates by pushing the Kingside pawns and permits White to catch up in development and push the Queenside pawns. Qb8 is an attempt to stop that strategy. The main problem is that White can play Nbd2 & Nc4 or Ne4 & the Black Bishop must move off the d6 square (Bxh2 is never a threat as long as White hasn't castled; all it does is "develop" White's King Rook by giving it an open file, and, even worse, stops the Kingside pawn roller). This then permits the King to step out of the center with Kf1 or O-O-O)

Correct against the Steinitz is 9...Bd6 10.d3 Bd7! (To keep the e6 square for the Knight on a5) 11.Ng1 Qb8!! so that a Knight hit on d6 can be met with Bc7. More importantly, Black forces White to deal with the hit on the b-pawn. If Black plays b3, then he has to be concerned about ideas like a5/a4. However, Nbd2/Nb3 is bad because it slows down the pawn roller on the Queenside, so Black wins on the Kingside.
The Rook isn't trapped because it has a Rook lift on the seventh or sixth.

In the Steininz, White only wins when Black rushes in; the correct way to beat White is to stay in Universal mode on the Kingside (i.e. all of your pieces are behind your pawn wall, push them forward in a coordinated manner until you win something big) and Classical mode on the Queenside (active piece play), deny White space, and then use Karpov's boa constrictor style.

Congrats Sloughter,
After a great many tries, you did produce a small innovation.


In fact he produced another one. The advantage of the trial and error method is that it sometimes delivers something useful, even if the inventor does not realize it himself.

4.Ng5 d5 5.exd5 b5 6.c3 Nd4 7.Bf1 Nxd5 8.Ne4 Ne6 9.d4 exd4 10.Bxb5+ Qxd7 11.Qa4 is a small improvement on 10.Bxb5+ Bd7 11.Qa4 Ndf4 12.d4.
By far not enough to justify "8...Ne6" +-, but it is something.

8...Ne6 9.d4 exd4 10.Bxb5+ Qxd7 11.Qa4 Ndf4 (but Black might have better) 12.g3 Nd3ch 13.Ke2 Nxc1ch 14.Rxc1 Rb8 (FM Dikkie), but this is probably not the last word.

It seems that the post on the Fritz-variation is now repeated.
To sum up
10.Qf3 doenst cause black any problems, but 10.0-0 probably does.

The point is that Black's King is badly placed, but White will suffer from an undeveloped Queen's wing for a while. So 8.cxd4 indeed is not as bad as some sources want us to believe, but it's too early to conclude that White has "a quite superior game". "Unclear" and "needs more testing" seem more appropriate, despite Black's fantastic results.

Hello, I am studying the subject Fritz-Ulvestad and this is maybe not a true refutation, but the intuitive (for human and computer) line with 5..b5 6.Bf1 Nd4 7.c3 Nxd5 8.cxd4 seems good to have a quite superior game, let's say a += at least. For example: 8..Qxg5 9.Bxf5+ Kd8 10.Qf3 Bb7 11.0-0 Rb8 12.dxe5!? Ne3(!) (it seems to me that 12..Nb4 is almost refuted) 13.Qh3 Qxg2+ 14.Qxg2 Nxg2 15.d4 where it's a middle game without Queens where White is a pawn up but Black have somes compensations for the pawn, they may have the bishop pair too, and the few games on the subject seems to confirm a balance, 4,5/9. But that's probably easier to play for White and may be a good practical choice for White, maybe a +/= that may tend to =, but who knows?

A question, perhaps, for another board and thread, but is chess really so logical?  I appreciate that in many situations there are "right" squares and "wrong" squares for our pieces, but the statement above seems to take that to the extreme.  Surely, achieving chaos on the board is one of chess' great joys and beauties--that you can take a symmetrical board and introduce anti-positional ideas that are still good?!


To play the devil's advocate, actually, yes, chess is perfectly logical. out. In "Questions of Modern Chess Theory",  Isaac Lipnitsky wrote “In any particular position, the rejection of some laws (directives) merely makes way for the affirmation and success of others.”   

I tend to agree with this. It just so happens that the truths of chess are so elusive that we have not figured them, and when we do, it will probably be so complicated that no one will probably be able to remember it all on the board.  Smiley

The silicone monster in antipositional variations can calculate 7-8 moves ahead. With luck, I can only look two or three moves ahead. When I played the computer in a variation that IM Silman analyzed as favorable to White, I lost 80 games in a row to Fritz just because it was antipositional. I'd trust the 'beast's' wisdom on this one. OTB it's a nightmare. In postal, with no takebacks of moves, it's a minefield. As a dry theoretical exercise, have Fritz 11 or another strong computer look at it.

The only two moves that seem forced are: 10.Qf3 Bd6 11.Nc3 e4. 
there are a lot of candidate moves here. We can start pruning branches of the thicket of variations. By bypassing 8...Ne6, this is more important than the Berliner Variation. I think you are right; there probably is a win for White here somewhere. Just as in the Berliner Variation, there ought to be someway for White to punish this forced loss of time in a sharp position. This looks like fun!sloughter wrote on 01/16/09 at 02:22:35:
