Carlsen is back at +1 and has White against Wang Yue. His last attempt in Slav Defense was an opening failure against Aronian but he should have done some repairs. The Chinese is generally playing very solid chess and his games are not that spectacular but the combativity of the young Norwegian may turn any game into a real show. Stay tuned at 16.00 CET.
1.d4 d5 2.c4 c6 3.Nc3 Nf6 4.e3 a6 Wang prefers the Chebanenko line instead of the more fashionable Meran.
5.Nf3 b5 6.b3 The old move. 6.c5 is more popular these days.
6... Bg4 7.Bd2 Nbd7 8.h3 Bxf3 In this structure Black is always ready to trade his Bishop for Nf3.
9.Qxf3 b4 10.Na4 e5 A logical attempt by Black to use his lead in development.
11.Rc1 Bd6 ( Winning a pawn is very risky: 11... Bd6 12.c5 Bc7 13.Bxb4 O-O 14.Be2 Ba5 ans White has it hard to coordinate his pieces.)
12.cxd5 cxd5 13.dxe5 Nxe5 14.Qd1 O-O 15.Be2 The opening resulted in a very untypical kind of position with isolated pawn. It should be evaluated as about equal. Black has no light-squared Bishop but his pieces a excellently centralized.
15... a5 16.Rc2 Qe7 ( I think that Black has to fight for the 'c' file while consolidating his grip on the center. A sample line to demonstrate the setup: 16... Ne4 17.Bc1 Rc8 18.Bb2 Qf6 19.O-O Qe6)
17.Bc1 Rad8 18.Bb2 Ng6 19.O-O Ne4 Wang is playing natural moves but letting White to control the 'c' file and a1-h8 diagonal may become a problem in the long run.
20.Bd4 Nh4 21.Bd3 Nf5 22.Bb6 Rb8 Clock readings: 1.03 1.04
23.Bxe4 Black pieces looked very menacing in the center but 23.Qf3 deserves attention.
23... Qxe4 24.Rd2 After a lot of considerations.I guess, calculating the consequences of the exchange sacrifice had cost so much time: (24.Rd2 Rxb6 25.Nxb6 Nxe3 26.fxe3 Qxe3+ 27.Rff2 Qxb6)
24... Rxb6 25.Nxb6 Qe5 Wang prefers to shatter the pawn cover of the King.
26.Re1 (26.g3 Nxg3 looks very dangerous but after 27.Nxd5 Nxf1 28.Kxf1 the position is about equal)
26... Qh2+ 27.Kf1 Qh1+ 28.Ke2 Qxg2 29.Rxd5 Ng3+ 30.Kd3 Bc7 Carlsen took a great risk and his King may soon end up in a very unpleasant situation.
31.fxg3 Bxb6 32.Kc4 Rb8 Perhaps this is the move Carlsen had missed.
33.Kb5 Clock readings: 0.01 0.33.
33... Bd4+ (33... Bd8+ should win in few moves.))
34.Kc4 Bf6 Now White is back in the game - 34...Bb6
35.Qd3 Qxg3 36.Rd1 Qc7+ 37.Rc5 Qb7 38.Qd6 Qe4+ 39.Rd4 Qc2+ 40.Kd5 Qg2+ Carsen survived the time trouble but his position remains difficult.
41.e4 (41.Kc4 Qe2+ 42.Kd5 Re8)
41... Rd8 42.Qxd8+ Bxd8 43.Rc8 g6 44.Rxd8+ Kg7 45.Rd3 Qc2 A patient player like Wang usually delays moves like 45...f5. His goal is to create a passed 'b' pawn first.
46.Kd4 a4 47.bxa4 Qxa2 48.Kc5 b3 49.Rb8 b2 50.Rdb3 Qxa4 51.Rxb2 Qxe4 Black won the 'e4' pawn, trading the potential weaknesses on the queenside in the meantime.
52.R8b3 Kh6 53.Rc3 f5 54.Rbb3 Qe5+ 55.Kc4 Kh5 Black plan is simple: King to 'h4' and pushing pawns.
56.Kd3 Kh4 57.Kd2 f4 58.Rf3 g5 59.Rfd3 Qc5 60.Rbc3 Qf2+ 61.Kd1 Qf1+ 62.Kd2 Qg2+ 63.Kd1 Qe4 64.Kd2 h5 White is completely helpless. And Carlsen resigned. 0-1
