| Oct-01-18 | | Sergash: At the time of this game, she was known under the name of Anita Hersvik, which later changed for Gronnestad after she got married. Born in October of 1982, she had turned 19 in the recent months and was allowed to participate in the "under 18" championship. Apparently she was never rated higher than a good Expert, reaching a maximum ELO of 2099 in 2005 (https://www.365chess.com/players/An...). In Chessbase, she is rated 1959 for that game. Carlsen, for his part, had recently turned 12 years old and was rated 2127 for that tournament. <2...Nb8-c6 3.d2-d4!> In a game played in 2001 against a player rated 2425 vs 2064 for Carlsen, Magnus had played 2...d7-d5 3.e4xd5 Qd8xd5 4.d2-d4 Nb8-c6 5.Ng1-f3 Bc8-g4 6.Bf1-e2 c5xd4! 7.c3xd4 e7-e6 8.Nb1-c3 Bf8-b4 9.0-0 Qd5-a5! 10.a2-a3 Bb4xc3 11.b2xc3 Ng8-f6 12.Ra1-b1 0-0 13.Rb1-b5 Qa5-c7! 14.h2-h3 Bg4-f5 15.Nf3-h4 Bf5-g6 16.Nh4xg6 h7xg6 17.Be2-f3 a7-a6 18.Rb5-c5 Nf6-d7! 19.Rc5-g5 Nc6-e7!? 20.Qd1-b3 Ra8-b8 ⩲ M G Petrov vs Carlsen, 2001, draw. <3...c5xd4! 4.c3xd4 d7-d5 5.e4xd5 Qd8xd5 6.Ng1-f3 e7-e5 7.Nb1-c3 Bf8-b4 8.Bc1-e3?> When he played 3...c5xd4!, Carlsen transposed in one of his previous games (M Weighell vs Carlsen, 2001, 1-0), where White had played 8.Bc1-d2! Bb4xc3 9.Bd2xc3! e5-e4 10.Nf3-d2?! (10.Nf3-e5! ⩲ Komodo 9.42 64 bits) Ng8-f6! 11.Bf1-c4 Qd5-g5! 12.Qd1-b3 0-0! 13.0-0-0?! (13.h2-h4!= Komodo 9.42 64 bits) Bc8-g4 14.h2-h4!? (simply 14.Rd1-e1! ⩱ Komodo 9.42 64 bits) Bg4xd1? (14...Qg5-f4! ⩱ Komodo 9.42 64 bits) 15.Rh1xd1?? (15.h4xg5! ⩲ Komodo 9.42 64 bits) Qg5-f5-+ 16.g2-g4? (16.Nd2-f1!

| Oct-03-18 | | Sergash: <11...e5-e4?! 12.Nf3-d2 Bg4xe2 13.Qd1xe2 0-0 ⩲> 11...e5xd4! 12.Nf3xd4 (12.c3xd4 0-0= Ladislav Knazovcik (2280) - Lubomir Kozlicek, Czech Republic Championship in Luhacovice 1993, round 10, 1-0; or 12.Be3xd4N!? 0-0= Stockfish 9 - 64 bits POPCNT) Bg4xe2 13.Qd1xe2 (also playable 13.Nd4xe2 0-0= Stockfish 9 - 64 bits POPCNT) 0-0= Hauke Dutschak (2240) - Aleksandar Vuckovic (2265), Wuerttemberg Championship (Germany) 1995, round 4, 1-0. <14.f2-f3?! e4xf3! 15.Nd2xf3 Nc6-a5!= / ⩱> Anita missed 14.Rf1-e1N! ± Stockfish 9 - 64 bits POPCNT. Note that 15.Rf1xf3 Ra8-c8= (Stockfish 9 - 64 bits POPCNT) might be better here. <16.Nf3-e5?!> Wanting to control Black's c4 outpost. Better play: 16.Be3-f2 Rf8-e8 (16...Ne7-g6 17.Bf2-g3= or 17.Qe2-d3= or also 17.Qe2-c2= Stockfish 9 - 64 bits POPCNT) 17.Rf1-e1= or 17.Ra1-c1= Stockfish 9 - 64 bits POPCNT. <16...f7-f6> More precise is to first play 16...Ra8-c8! 17.Ra1-c1 (or 17.Be3-d2 f7-f6! 18.Ne5-d3 Ne7-g6 ⩱ Stockfish 9 - 64 bits POPCNT) f7-f6 18.Ne5-d3 Qd5-f7 ⩱ Stockfish 9 - 64 bits POPCNT. <17.Ne5-g4> Why not 17.Ne5-d3!= / ⩱ Stockfish 9 - 64 bits POPCNT. <17...Ne7-g6?!> 17...Qd5-c6! 18.Ra1-e1 Na5-c4 ⩱ Stockfish 9 - 64 bits POPCNT. <18.Qe2-c2?! Na5-c4 ⩱> 18.Be3-d2!= Stockfish 9 - 64 bits POPCNT. <19.Rf1-f5?? Qd5-e6!-+ 20.Be3-f2 Nc4-d6!▢ 21.Ng4-e3 Nd6xf5▢-+> A terrible mistake... 19...Ra1-e1 ⩱ or 19...Be3-d2 ⩱ Stockfish 9 - 64 bits POPCNT. |

| Oct-07-18 | | Sergash: <24.Nf5-g3?!> Stronger is 24.Nf5-e3-+, still losing though. Stockfish 9 - 64 bits POPCNT. <24...b7-b6> Enough for the win, but 24...Ra8-c8! with the idea 25.Rb1xb7 Ne7-d5-+ is stronger. Stockfish 9 - 64 bits POPCNT. <25.Rb1-e1?!> Anita seems to struggle to setup a plan. More commendable is 25.c3-c4 Ra8-c8! 26.c4-c5-+ Stockfish 9 - 64 bits POPCNT. <25...Qe6-f7?!> The general level of play seems to have deteriorated since the last few moves! Carlsen, knowing he is winning, was possibly losing interest or his focus in the game. The obvious 25.Qe6-c4!-+ is much stronger. Stockfish 9 - 64 bits POPCNT. <26.Ng3-e4> Again, better is 26.c3-c4 f6-f5 27.c4-c5-+ Stockfish 9 - 64 bits POPCNT. <26...Ne7-d5> 27.Ne4-d6 is not a threat because of 27...Re8xe1+. Still, the best move appears to be 26...Ra8-d8!-+ Stockfish 9 - 64 bits POPCNT. <27.Qc2-b3> Better is 27.c3-c4!? f6-f5! 28.c4xd5 Re8xe4 29.Re1xe4 f5xe4 30.Qc2xe4 (30.d5-d6 Qf7-e6-+ Stockfish 9 - 64 bits POPCNT) Ra8-e8-+ followed by Qf7xd5. Stockfish 9 - 64 bits POPCNT. <28...f6-f5 29.Ne4-g5 Re8xe1+ 30.Bf2xe1 Qf7-e7 31.Be1-d2 -+> Stronger: 28...Nd5-f4!-+ Stockfish 9 - 64 bits POPCNT. |

| Oct-08-18 | | Sergash: <34...Rd8-c8! 35.Bd2-f4 Qd6-d7▢ 36.Bf4-e5 h7-h6!-+> Of course not 34...Qd6-c7?? 35.Ng5-e6 ∓ and Black is not winning anymore! And after 35.Bd2-f4 of course not 35...Qd6xf4?? 36.Qb3xd5+ Kg8-h8 (or 36...Kg8-f8 37.Qd5-f7#) 37.Qd5-d8+ Rc8xd8 38.c7xd8R# or 38.c7xd8Q#. <37.Ng5-f3> Anita could have gone with 37.Ng5-h3 instead, planning Nh3-f4. But after 37...Kg8-h7!-+ Black doesn't have any difficulty winning. Stockfish 9 - 64 bits POPCNT. <41...Qd7-c6 42.Nf3-e1> 41...Rc8-c1+! 42.Kg1-f2 Rc1-c3-+ Stockfish 9 - 64 bits POPCNT. <45.Qa3xa7?! Rc8-c1! 0-1> 45.Qa3-f3 would have lasted a few more moves, but after 45...Rc8-c1! 46.Be5-g3 f5-f4! 47.Bg3-f2 Nd5-e3!-+ there is no light at the end of the tunnel... Stockfish 9 - 64 bits POPCNT. The game moves reflected the difference in strength between the two players. After the blunder 19.Rf1-f5??, the already inferior White position became hopeless and Carlsen never gave any chance of a comeback. |
