Apr-18-09  Bautismo: Nice display by Carlsen on increasing the pressure on the pawns to move them forward

  alexmagnus: Looking at where and when the game was played... LOL, I imagine it - in the Nordic team championship they let the kids battle it out. Would be funny if the game was decisive for the outcome of the team match :)
Sep-02-14  MarkFinan: Still think this is a great display of Lock. Maneuver. Crush. From a boy of his age anyway. I¬†couldn't really see the blunder from black until I ran the game though the engine, but I don't think black should have exchanged queens because it made any defence he had a lot harder. And a forced mate in 6 from this position.

Jan-08-16  Sergash: Jon Ludvig Hammer was born the same year than Carlsen and in July 2015 was the the #2 player of Norway with a Elo of 2677 (World #63). He was also a Carlsen helper for the 2013 World Championship. He is a grand master since 2009.
Jan-08-16  Sergash: <14...a6?!> 14...Nb6= or 14...a5= appear to be the only moves maintaining equality. Now after 15.a5! Carlsen blocks the Q-side, leaving the c6-pawn vulnerable on an open file.

<17...Rfe8> (why not 17...Bxg3 18.hxg3 ) <18.Rfc1> a logical move, but interesting was: 18.Bxd6 Qxd6 19.h3 Bh5! 20.Bf5 Komodo 9.2 64 bits.

<19...Kh8!? 20.Na2> interesting but possibly stronger was, for example, 20.Rb2 Bxg3 21.hxg3 Qd6 22.Nd2 Komodo 9.2 64 bits.

<20...Nb8?!> 20...Ne8! with the idea of Bxg3 and Nd6 . Komodo 9.2 64 bits. After 20...Nb8?! 21.Nc5! Black cannot trade this strong knight...

<22.Bf5?! Bxf5 23.Qxf5 > Again 22.Bxd6! Qxd6 23.h3 Be6 24.Rb2 Komodo 9.2 64 bits.

Jan-08-16  Sergash: As MarkFinan pointed: <(...) I don't think black should have exchanged queens because it made any defence he had a lot harder.>

On the Komodo engine, <29...Qxf3?! 30.gxf3 >. Instead, 29...Re6! .

<31...Nb8> is inferior. Sronger is 31...Re6! .

<33.Rc5> (threat: 34.Rxd5) <Rec7 (only move) > Of course not 33.Nxc6?? Rec7 34.Nxb8 Rxc3 35.Rxc3 36.Nxa6 =.)

Magnus made a mistake on <34.e4?! dxe4 > and Jon could breathe more lightly! White had to take his time. For example, he could bring the king closer to the centre with 34.Kg2 .

The losing move: <35...f6?! 36.Ng4! > 35...Re7! 36.f3! Rd8 37.Ng4 (or 37.Rd1 Re6 38.Ng4! followed with Nf6) Rxd4 38.Ne3! (threatening the fork Nf5+) Kf6 Komodo 9.2 64 bits.

<37...Kf7 38.Nf5> (threatening Nf5-d6+) <Ke6?!> (better is 38...Kg6) 37...Re8!

The final mistake was <42...Re8?>. White was threatening Re5-e7+, but the 'lesser evil' was 42...Rh8, freeing the c8 square for the black king.

<44...Rc7> The longest survival was through 44...Ke8 45.Re1! (even stronger than 45.Nd6+) Rxe7 46.Rxe7+ Kd8 47.Ra7! but only a machine would go for such a line (here Komodo 9.2)! After 44...Rc7 and as was already mentioned in previous posts, White mates in 6 moves starting with the played <45.Rd1+!>

The mate in 6 moves goes as follows:

45.Rd1+! Ke6 46.e8Q+ Kxf5 47.Rd6 Re7 48.Qxe7 Kg4 (if 48...g4 49.Qf6+ Ke4 50.Rd4#) 49.Qe6+ Kf3 50.Rd3#

I skipped all the shorter mates along the way.

May-09-23  Gaito: There is a YouTube channel where this game is analyzed and discussed (, but the opening moves are given in different order, namely:

1.d4 d5 2.c4 e6 3.Nc3 Nf6 ed 5.Bg5 Be7 6.e3 c6 7.Bd3 Be6 8.Nf3,

which seems to be a more logical way of playing the opening moves (for both sides), and the same position is reached after White's eighth move.

My question is: What was the real order of moves of this particular game in the opening before the ninth move?

May-10-23  Gaito:

This is the so-called "Carlsbad Pawn Structure". In the old days of the classical masters, White's most common plan was to undertake the typical "minority attack" with b2-b4 and then the breakthrough b5, and so forth (see diagram below):

A typical example was the game Capablanca vs Golombek, 1939 (see diagram below):

That game can be seen in this link: Capablanca vs Golombek, 1939 In the Carlsen vs. Hammer game White adopted this old strategy. Nevertheless, some modern mastres sometimes prefer a different plan, namely to prepare a K-side attack with White, which is also feasible.

May-10-23  Gaito: There are plenty of examples of games with the "Carlsbad Pawn Structure" where White managed to successfully undertake the "minority attack" on the Q-side (b2-b4-b5). Another good example that comes to my mind is the game Geller vs. I.A. Horowitz, 1954. See the following position:

May-10-23  Gaito: As mentoned below in another of my comments, regarding the "Carlsbad Pawn Structure" White has an alternative plan, (instead of undertaking the minority attack b2-b4-b5) and that is to castle queen-side and carry out a K-side attack. An example that comes to my mind is the following position

This is from a game Geller vs Averbach, USSR Ch., 1950. White castled long and attacked on the K-side. A very nice game! The game can be seen in the following link:

Geller vs Averbakh, 1950

I remember that also Garri Kasparov used to attack on the K-side with White when he had the Carlsbad Pawn Structure.

Personally, my humble opinion is that the minority attack on the Q-side is the easiest and most logical plan to carry out with White, as in the Capablanca vs. Golombek game mentioned below.

May-10-23  SChesshevsky: <...order of moves of this particular game...>

Don't know but ...Be7 before ...Nf6 is the Charousek -Petrosian QGD trick stopping Bg5. At least for a bit. But seems to most often just transpose.

Black playing ...b5 to hinder the minority attack (and sometimes to suggest 0-0 for white) is very committal. Here follow up just saddles black with the backward ...c pawn.

In recent Erigaisi-Kramnik Satty blitz, Kramnik's ...b5 was followed up with quick queenside counter play. Not sure if it's best but likely better than the backward ...c pawn.
