　　In double round robin tournament when you are losing first game, you have a chance for revenge. Today also everybody expect that Topalov will give big fight to young star Carlsen!

　　1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 6.Ndb5 d6 7.Bg5 a6 8.Na3 b5 9.Bxf6 gxf6 10.Nd5 Bg7 11.Bd3 Ne7 12.Nxe7 Qxe7 13.0–0 0–0 14.c4 f5 15.Qh5 Rb8 16.exf5 e4 17.Rae1 Bb7 18.Qg4 Rfe8

　　Magnus is repeating same line which bring him pain in Sofia against Shirov in the last round

　　[In database we discover several interesting games issuing other lines 18...Kh8 19.Bxe4 Bxb2 20.Re3 (20.Bd5 Qc7 21.f6 Bxf6 22.Qf5 Be5 23.Rxe5 dxe5 24.Qf6+ Kg8 1/2–1/2 Luther,T (2536)-Muzychuk,M (2427)/ Neustadt an der Weinstrasse 2009/CB09_2009) 20...Bxe4 21.Rxe4 Qf6 22.Nc2 bxc4 23.Rxc4 d5 24.Rb4 Bc3 25.Rxb8 Rxb8 26.Ne3 d4 27.Nd5 Qe5 28.f6 Rg8 29.Qd7 Qe8 30.Qe7 Ba5 31.Rd1 Qa4 32.Qe2 Rg5 33.Rb1 Rxd5 34.Qg4 1–0 Shirov,A (2730)-Markos,J (2565)/Montcada 2009/CB39_2009]

　　19.cxb5 d5 20.bxa6 Bc6 21.Rc1

　　Normaly such a move should be novelty, but...

　　[In upside mention game between Shirov and Carlsen, Alexey continued 21.b3!? Kh8? (After Carlsen lost a game, other lovers of Sveshnikov variation continue research of this line, find better defense 21...h5! 22.Qg3 Kf8 23.Nb1 Be5 24.f4 Bf6 25.Qf2 Qb4 26.a3 Qd4 27.Bc2 e3 28.Qf3 Bb5 29.Re2 Bxa6 30.Qxh5 Bxe2 31.Qxe2 Rec8 32.Kh1 Qb2 33.Bd3 Qxe2 34.Bxe2 Rxb3 35.g4 Rcb8 36.g5 Rxb1 37.gxf6 Rxf1+ 38.Bxf1 Rb2 0–1 Koch,J (2453)-San Emeterio Cabanes,J (2392)/Le Port Marly 2009/CB23_2009) 22.Nc2 Be5 23.Be2 d4 24.Bc4 Rg8 25.Qh3 Rg7 26.g3 Rbg8 27.Qh6 Qc7 28.Nb4 Ba8 29.Nd5 Qd8 30.Rxe4 1–0 Shirov,A (2745)-Carlsen,M (2770)/Sofia 2009/CB22_2009]

　　21...exd3!N

　Before this move, first time in this game, Carlsen start thinking, but the same time showing that, for him Rc1 is well known move and he is trying just to remember how to play next moves

　　[We find only this game in chess data 21...Bd7 22.Be2 Rxb2 23.Rc7 Qd6 24.Rfc1? (24.Rxd7! Qxd7 25.Bb5 Rxb5 26.Nxb5+-) 24...d4 (24...e3–+) 25.Bc4 d3 26.Qh5 Re7 27.a7 Qxa3 28.Bd5 1–0 Koeller,O (2290)-Schelle,A (2150)/Aschach 1998/EXT 2000]

　　22.Rxc6

　　and again Magnus start to play fast with slight smiling

　　22...Qe2 23.h3 Rxb2 24.f6

　　Difficult to comment when all this moves are so obvious

　　24...Qxg4 25.hxg4 Rxa2 26.Nb1 Bf8

　　27.Rc3

　　[It looks much dangerous for black 27.Rd1 but after right move 27...h6! (Worse is 27...Ra1 28.a7 d2 29.Kh2 d4 30.Kg3 Rxa7 31.Nxd2 Ra3+ 32.f3 Rd3 33.Rcc1±) 28.a7 (28.Nc3? d2 29.Nxa2 Re1+ 30.Kh2 Rxd1 31.a7 Rh1+ 32.Kg3 d1Q 33.a8Q Qd3+ 34.f3 Qe2µ) 28...Rxa7 29.Nc3 Bb4 30.Rxd3 Ra1+ 31.Kh2 Rc1µ Threatening d4]

　　27...Rxa6 28.Rxd3 Rxf6 29.Rxd5

　　[Again it looks white is getting advantage after 29.Nc3 Bc5 30.Rf3 (30.Nxd5? Bxf2+!) 30...Rxf3 31.gxf3 Rd8=]

　　29...Bb4!

　　Cutting white's Knight!

　　30.g3

　　[30.Nd2 Bxd2 31.Rxd2 Rfe6=]

　　30...Re2

　　Rest is very clear and no need for any comment. Just we can make a conclusion that, Carlsen and his team (we know this is Kasparov!) working hard and for any opponent will be difficult to surprise in the opening Magnus

　　31.Kg2 Be1 32.Rf5 Rxf5 33.gxf5 Bb4 34.Rc1 h5 35.Rc4 Rb2 36.Nc3 Bxc3 37.Rxc3 Rb5 38.Rf3 Kg7 39.Kh3 Kh6 40.Kh4 Rb1 41.Kh3 Rb5 42.Kh4 Rb1 43.Kh3 ½–½
