If development of pieces and space control are prime objectives of the "opening stage", Black seems to have somewhat easier job now than at the start. Then, comment by Toni Kosten from cro777's previous post may be taken in account and almost state that Black's pieces are more actively posted while space control is in balance and I'd speculate that White is "on defensive" here contrary to the starting position. So, what is right long term strategy in order to finish development and reposition the pieces in order to achieve the condition for an attempt to gain more space FIRST and create an attacking threat. |

The same strategy can be seen in their aforementioned games against Andreikin. |

(White's set-up is similar to to the Italian game, only the light-squared bishop is on b5 instead of c4).....> Like usually you are right, and your knowledge of the main stream chess development and protagonists is incredible. I have small booklet containing good numbers of games from 19th century, collected by Dufresne and Mieses (from antikvarijat in Gunduliceva), also From Steinitz to Botvinik and will try (I'll take my time though) to find some "oldies goldies" for Italian opening. Perhaps "deep thinkers" from that time had some idea that got missed by modern "hi-tech" teams. I tried briefly during early stage of the game against GMARK but may be worth second try. As for the Italian opening, as I recall, Blacks got scared from the c3-line and Whites from an easy draw by the opponent and "boring play". As our Team showed, and also the teams assisting modern top players, nothing is either "boring" or certain any more. This is good opportunity to mention recent magnificent effort by AylerKupp (on his site) in multiple-engine scrutinizing famous position from Fisher-Geller, Skopje 1967 ( Fischer vs Geller, 1967 ) where Fisher unleashed incredible attack but lost the game due to one missed move which was few hours later found as winning and that held as certain until AylerKupp put a "glimmer of uncertainty" to that assessment. |

Interestingly, Naiditsch didn't mention our game against him. <OhioChessFan> You are quite right. The reason for the "duplication" was that someone from our Team, while waiting for the next GM challenge, might be interested to join the game against a very strong grandmaster (who's paying enough attention to the game).

member cro777: It might be interesting to see Naiditsch's comments on the recent game Svidler - Markus Ragger (Schachbundesliga, March 15th, 2015) in the 4.d3 Anti-Berlin. >I looked up this game. Too bad Ragger erred with 22...Nd5 instead of better, engine selection Nc6. I'm wondering how would Naiditsch proceed after 22...Nc6 and would the continuation be just "game won by player who errs 2nd last". Actual game just looks as "surprise preparation" and "deeper memory" of the OTB (2600+) player, not applicable to "our type" of games. During our game I'm pretty sure Naiditsch had this particular line already worked out much deeper than his recent opponent now. I'd say "beware of players who play the same opening with either color of the pieces". |

| Mar-23-15 | | cro777: GM Naiditsch's annotations are from the latest issue (Nr.160) of the Chess Evolution Weekly Newsletter (CEWN). He selected the game Svidler - Ragger as a theoretically important one. This is an indirect recognition by experts (both Naiditsch and Svidler are experts in this Anti-Berlin system) that the World team's opening play was "state of the art". The game has also been video-annotated by GM Jan Gustaffson here https://chess24.com/en/live/video/s... <yskid: Too bad Ragger erred with 22...Nd5 instead of better, engine selection Nc6.> You are probably talking about different game. Ragger played 22...Nb6 (the d5 pawn was safely protected and the knights were ready to occupy their ideal outposts). |

"Black should have tried the more strange-looking 22...Nc6 but if we think from a general point of view, this move is not that hard to find, since Black has 2 pieces for a rook, which means that the 2 pieces should attack something of White and with this move we attack the d4 pawn. 23.Bxf8 Nxf8 24.Nd6 and I still believe that Black’s position is at least very dangerous, but things are objectively unclear aft er

click for larger viewWhite has to find the best plan in this position.
The plan that had occurred in M F Noble vs I A Nataf, 2012 (followed by Svidler as well) was considered the main line: 12.Qb3 d5 13.e5 Nd7 14.a4 a6 15.Be2 c5 16.e6
click for larger viewThis is what I posted during the game: "Black has fully equalized and has no structural weaknesses. In such a situation it is necessary to try to change the pawn structure in order to create some weaknesses in the opponent's camp. In the mainline White tries to achieve this by playing e6 at the appropriate moment." Instead of 15.Bd2, Svidler opted for 15.Bd3 ("This is clearly the best place for the bishop", Naiditsch) and after 15...c5 sacrificed a piece! 
click for larger view16.g4!? Naiditsch: "This very interesting piece sacrifice was clearly
Svidler’s home prepared idea, which started with 14.a4!?. Now things are
getting very complicated."
The Team decided to deviate from the main line, because 12.Qb3 leads to negative computer evaluations, and opted for 12.a3. The Team also gave preference to a less expected move, forcing the opponent to think (Tabanus:"There is one reason to deviate: we'd force him to think"). It was a close decision: 12.a3 (115 votes), 12.Qb3 (102 votes). |
