The brilliant game that won the Grand Yucatan Black Maestro Manuel León Hoyos Swedish GM Emanuel Berg in his recent performance in Norway. technical analysis and opinions of international master director Edarays. This is the first part of this collaboration:
A game of romantic, just that-this point in the evolution of the art chess romanticism is not a music rhythm only exit to the emotion associated with a fierce fight for the initiative as it did in the late nineteenth century with classic romance.
The model Grandmaster Leon gave us as black, in his departure from the seventh round in Arctic Chess Challenge 2010, held in Norway, compared with Swedish GM Emanuel Berg, has the characteristics of Neoromanticism, where the intensity of the departure can be explained with rules and more or less clear technical principles, but profound.
Try avoiding complex variations of deep and accurate concrete calculation and try to analyze the game on conceptual bases, so you can feel a little madness with reason.
My friend the GM Silvino Garcia would tell me, "You always trying to catch the excitement of a rule that can be taught, as long as utopian." Well, some of us must play generalizing work of the arid and necessary Pedagogy. 1.d4 Nf6
Defense Indobenoni result of a way of cutting the pawn chain, where a pawn apiece, being these in different columns, that determines asymmetry in the chain is changed.
In asymmetrical pawn chains, each side has at one side of the board a majority and a minority of other laborers, these being crossed: white majority and black minority in an area and the reverse on the other side.
To split the board we draw the line between diagonals from the central end of the longest piece of string. In this case the line asymmetry is between the d and c olumns; then divide the board into two sections: I queenside and center flank king.
In the first we have black majority and white minority; in the second, most are white and the minority is black.
Asymmetrical pawn chains are very mobile and changing, what intense transformations that require greater accuracy in the game both opponents are derived. Yes, chess is more intense in asymmetric positions.
In Havana-Merida System intended as a way to explain hypermodern strategy, tactics and the humanist sense of chess, basic rules are given to guide us in asymmetrical positions:
1) There are two types of attacks in mobile-based asymmetries pawn:
'The minority-minority attacks.
'The attacks majorities majorities.
Caution: in each case, the parts of both sides develop very differently and the player must be able to identify appropriate when a type of attack or another. To guide give the following rule:
"If no central end of long, white or black string, manifest advantage of space, come Attacks on Minorities; otherwise they shall Attacks Majority. "
As can be seen in the position come the attacks and the white majority must project its development based on the progress of their pawns on the king side and black center with advancing his pawns wing lady.
The rule says to do, the particular technique will tell us when and that's something finely referred to in his eloquent and masterful chess models like to try this game.

Black has developed the natural and only way that comes to them. White, meanwhile, have many options to develop their pieces of different shapes, each with a particular idea that characterizes it.
The different forms of development and natural white and black inelastic shape development in the first dozen plays, both, white and black, are required for a voltage of struggle that we define in a general way:
In Havana-Merida System Strategy we define as "Technical considerations aimed at projecting evolution of the eigenvalues and simultaneously blocking the evolution of the values of the opponent."
This asymmetrical position, the type of attack majorities, should be preliminary to perform such attacks, as they face a greater space of the opponent which translates to parts located more activity and that activity must be neutralized before investing time throwing the each pawn majority, as is theoretically derived.
Note that we talk about a strategy that is the same for each side in these cases. Then the voltage is large and a bit so we can define as follows:
"You can take the most attack and even less can accelerate the opponent before neutralizing activity in their own sector and more space less pawns."
The white idea contrafiancheto in Indobenoni Defense is to block the advance of the black pawns on the wing lady, while the king remains in e2 pawn to stop the black aimlessly activity in column e. Then impunity accelerate the progress of the white pawns on the kingside.
Here's how you can face the black to white that idea.
9- ... Re8
This horse goes to c4 box, where it will act on the black d6 weakness and that is very worrying for the black; Therefore you have to focus on that white neutralize threat.
10 ... Nd7
This horse goes to "hunt him fight" aggressive white horse.
This move is very elastic, based on natural preparations to move the pawns on the kingside checking before the g4 square and giving space to the white king to a check on possible future black diagonal g1-a7. Black now face the dilemma of what to do with your horse in d7 must vacate lady to develop the bishop, but can not do so because e5 help the advancement of the white pawns with f4 and e4.
11 ... a6
12 a4 RB8!
The sign is the focus: the black face with white elasticity elasticity, as dictated by the art.
No elastic to do to move more white that is as good as it was 11.h3, then you must define at last.
13 ... Ne5
The idea explained.
Just met with one important rule: "The side with the disadvantage of space benefits from changes in pieces." Logically White does not want to benefit the black.
Black now has the problem that his horse could help e5 white majorities in their attack and rewind seems counterproductive logically.
14 ... Ch5!
A tremendous solution: Black is preparing to fight back the attack of the white majority, and the time required to achieve material is reversed.
Do not miss the comments below this heading, where we see one of the most dynamic schemes derived attacks Most-most:
The counter to the advancement of majorities through sacrifice of material.
Always order more elastic. Both plays e4 and f4 are associated with a decision White: throw and attack majorities, but still always have to deal with the elasticity, which is a guiding principle in the strategic and tactical use of time with masterly precision.
Now Black must also make decisions about whether to continue with the approach to counter the attack of the white majority, by the time gain by sacrificing material. In this case it is up making the right play to continue with the idea.
15 ... d7!
This is the exact move for the foregoing purposes. The alternative was 15 ... c4, but the text is much better.
The white evaluated poorly counter the black and allow. The right thing would have been to play 16.g4. Then the game could have continued: 11 ... b5! (11 ... Nf6? 12.g5 Ch5 and then another with white 13.f4 strategy would be successful) 12.ab ab 13.Cab5 14.Cb5 Rb5 15.gh Bb5 16.Qe2 Nc4 and position is extremely uncertain, but the possibilities are equivalent.
16 ... Ng3 17.fe
Probably if 17.Tf2, had been continued: 17 ... Cc6! 17.DC Ac6 18.e5 of 19.Dd8 Rad8 20.Rg2 Cf5, with a slight advantage of black. Regarding 17.Te1, black would have been clear advantage after 17 ... b5 18.ab ab 19.Cc2 Qh4.
17 ... Ae5!
In chess, sometimes deciding between two alternatives fails to complete a matter of logic and accuracy being necessary to the final finish by our excitement outside in a bit incomplete reason. Reasons is difficult to say whether or not this move is better than the alternative 1 ... Cf1, but eventually the text asks the excitement and yes you're right, it is the best move.
Again the uncertainty, always so beautiful and educational. You have to decide between 18.Tf2 and 18.Tf3 and here we do not advise, from the point of view of the defense side, guided by emotions as much as the previous black decision. Let's see: In defensive positions, while lower, defensive resources must be coordinated based on the following rule:
"We must choose routes defensive generating greater technical difficulties and his human time for the top side."
In the position Black has a strong trio of pieces (two bishops and a horse) that is his great offensive force:
"The quality of a strong trio of minor pieces has two basic stamps given in the respective activities of different horse and bishop."
The hardest choice for Black would have been decided differently surrender his bishop after 18.Tf2! (help here theoretical calculation rule, like any good rule: 18 ... Ne4 Ac3 -necesaria- 19.bc 20.Ae4 Re4 21.Df3 22.Af4 Df6 f5 and black advantage is minimal or perhaps zero).
18 ... b5 19-ab ab
The advantage of black is already clear.
It is very difficult to defend in chess, but it was worth trying to complicate although it may, as in this case, accelerate the deterioration of the defensive position on an exact match of the attacker as happens here.
20 ... f5! 21-Rg3
(The black is already decisive advantage and alternative 21.ef not change that assessment, after 21 ... Cf5 22.Af2 Ch4).
21 ... g3 22.Df3 Qh4
More accurate was 22 ... h4 !; 23.Cb1 idea with 24 ... b4 Te4- +).
23.ef b4 Rf8 24.fg 25.gh Kh8 26.De4 27.Dh4 bc cb ba = D 28.Dg3 29.Rh2 Dc3 30.Cc4 Dc4 31.Dd6 Tbe8 32.Ah6 Rf7 33.Dg6 Tef8 34.Dd6 Rfe8 35.Dg6 Qh4 36.Ad2 Tg7 37.Ac3 (0-1).
A beautiful game of Yucatan Gran Maestro
