 | | An Englishman: Good Evening: The game follows such well-known paths in the Semi-Tarrasch that the praise slightly puzzles me. The sequence of d5, e5, and finally Nd4 has appeared before (didn’t Kmoch call it a “sweeper-sealer” pawn sacrifice?). Can’t deny that the finish looks like Fischer at his best. |

| Jul-06-20 | | SChesshevsky: <...for the commentators to consider this game a masterpiece...> Certainly nice play by Magnus. But Giri not seeming that familiar with the opening and going way down on the clock probably influenced the outcome more. It feels like whites always a bit better in these semi-tarrasch exchange variations. Blacks best drawing chances seem to be if one has put the time into working out clear equalizing ideas like I believe Leko and the Chinese like Ding and Wang Hao have done. Or be extremely clever and dynamic like Kramnik. Even in those cases, draws aren't usually simple. Without some clear ideas and being way behind on the clock, the chances for a bad semi-tarrasch result probably go up significantly. |

In the game Kasparov vs Najdorf, 1982 Stockfish indicates that it took just one mistake - the wrong rook by ...Rae8 instead of ..Rfe8 - to give White an advantage instead of equality One alternative to 18...Ne4 is 18...Nd7 offering to return the pawn at once eg 19 Bxd5 Bxd5 20 Qxd5 Nf8 |

 | | AylerKupp: <SChesshevsky> It feels like whites always a bit better in these semi-tarrasch exchange variations.> I agree, but it's more than just a feeling, certainly at the top level. The ChessTempo database has 2,015 games where both players are rated 2400+ after 1.d4 Nf6 2.d4 e6 3.Nf3 d5 4.Nc3 c5. It has White winning 30.1%, drawing 55.9%, and losing 14.0%. That's a scoring % of 58%, more than the usual 55%. It always seemed to me that in this opening Black works very hard and must play accurately in order to just to hold a draw. It's like a Grunfeld, Exchange variation but without the dynamic play provided by Black's Bg7. Why would Black players play this at the top level, particularly if they are hoping for a win? Perhaps this is one example of hope springing eternal. Oh well, maybe when I become a top player I'll be able to answer that question. ;-) |

| Jul-07-20 | | MordimerChess: A lot have been said already about the game and variations. But remember - we always need two players to create a masterpiece :D My video analysis:

| Jul-07-20 | | SChesshevsky: <...Why would Black players play this at the top level, particularly if they are hoping for a win?...> Probably some players like the semi-tarrasch as by passing the exchange lines with e3 or Bg5 can allow Black a freer version of the QGD. Though it's probably true that wins with Black in the exchange version might be more flukes than anything else. Maybe trying to be too tricky with Black just increases losing chances. An example might be:
Carlsen vs Kramnik, 2016 But seems white has enough out of the opening that passivity probably dooms black as well. Seems the trick is to just get enough counter play to draw. A tricky balance. Feels great when accomplished but really frustrating when lost. Couple interesting counter play draws were:
Gelfand vs Kramnik, 2017 Mamedyarov vs Ding Liren, 2019 |

| Jul-23-20 | | tonsillolith: That knight on <f5> is really well placed. It serves so many different purposes in the final sequence, including enabling the <30. e6> push by protecting both queen and rook. It comes quite close to having all four rear moves serving defensive purposes and all four forward moves serving attacking purposes. |

Anish Giri played here 23...Ne6, a move that looks logical and not too bad, yet with it Black allows the White knight to occupy f5. Black might have tried 23...Bc8 or 23...Qd7 instead, with an eye on f5 so that White's knight could not jump onto that important square. |
|
| Oct-10-23 | | Gaito: Kasparov once stated that "Carlsen's style is a lethal combination of Karpov and Fischer". I guess he had in mind games like this one when he said that. In this game Black was not guilty of making any big mistake, but just a few "little mistakes" or "tiny mistakes". Karpov was a master of exploiting "little mistakes" by his opponents. Here we see Magnus Carlsen as a master of exploiting very little mistakes by Anish Giri. And when the position was ripe, Magnus finished the game off just like Bobby Fischer would have done, in the most speedy, brilliant and precise way. This is a breathtaking game by Carlsen, and it was a rapid game! |

In the diagrammed position Black played 25...Nc5. Not too bad, but it is in fact another "little mistake" by Anish Giri. This can only be disclosed if we analyze the position with the aid of a powerful engine. Komodo 13 suggests that Black play 25...Bd5! with the following possible continuation: 25...Bd5 26.Nd6 Bxb3 27.Nxe8 Rxe8 28.axb3 h6 29.Qg3 f6, with an evaluation of +0.77. After 25...Nc5 the engines's evaluation is +1.19. |

BLACK TO MOVE
This position is extremely difficult to defend for Black, and more so in a rapid game with just a few minutes on the clock. Therefore, Anish Giri might be forgiven for having chosen the losing move 29...Rd8, which allowed a brilliant finish by Magnus. The engine (Komodo 13) gives the position as clearly favorable for White, and gives as the best possible defense for Black the surprising move 29...Bxf3!?, with the idea that if White then plays 30.gxf3?, then 30...Qc1+ 31.Kg2 Qc2+ 32.Qf2 Qxf5. Very likely Anish Giri would have seen all this if he had just more time to think. However, after 29...Bxf3!? White could play 30.Rc4! with an evaluation of +1.51. |

| Oct-10-23 | | Gaito: The opening moves of this game were highly theoretical (or "book moves"), which make this game an important one for the theory of the Semi-Tarrasch Defense of the QGD.

17.d5, as played by Magnus is the main "book move", but some other moves have also been played in this position. For example 17.Qe1. Also 17.Qd3 has been played, (e.g. Wesley So vs. Leinier Domínguez, a game that ended in a draw.) |

18...Ne4, as played by Anish Giri is the main line (or "book move").
Some other moves have also been tried here, for example: 18...Nd7, as played in a game Carlstedt (2444) vs. Colpe (2348) which ended in a draw. I am far from being an opening expert, but I just found this information in big database available in internet (it is free). |

Anish Giri played here 19...Qc7, which had been played before several times. Other moves have also been tried in the diagrammed position. In a game Yuniseky Quesada (2515) vs. Díaz Pérez (2460) from a championship of Cuba Black played 19...Nc5! which appears to be the best move, or at least the move that engine Komodo 13 suggests. |

20...a6 was apparently a theoretical novelty (but not a very impressive one). In a game Amartuvshin (2350) vs. Batchuluun (2536) the game went as follows: 20...Rxe5 21.f3 Rh5 22.h4 Nd6 23.g4 Rh6 24.Nf5 Qc5 27.Ne7+, and White won in 34 moves. What is Black's best move in the diagrammed position? The engine (Komodo 13) likes either 20...Qc5 or 20..Rcd8 (with equality in either case). In a game played at the Chennai Olympiad on July 8, 2022 between Lee (2390) and Tin (2552) there followed 20...Qc5 21.h4 b5 22.a3 Qb6 23.f3 Nc5 24.Kh1 g6 25.h5 Ne6 26.Qh4 Nxd4 27.Rxd4 Rc1+ 28.Kh2 a5, and Black won in 53 moves.
