White trys to get out c1 bishop and Bg5 is not that good } ( 4...dxc4 5.e3 b5 { Black is trying to hold on to c4 pawn but it's too early } 6.a4 a6 ( 6...b4 7.Na2 { White will win one of the pawns b4, c4 back } ) 7.axb5 cxb5 8.Nxb5 axb5 9.Rxa8 ) 5.e3 { capture of c4 is defended now } ( 5.Bg5 { This is not such a good move because black is able now to capture c4 pawn and hold on to it } dxc4 6.e3 b5 7.a4 Bb7 { The rook is protected now and also b5 pawn will live } ) e6 { semi slav } 6.c5 { Grab some space and control b6 and d6. Here black has to make a decision to live with this pawn or not on his own territory and this can happen by moving b6 } Nbd7 ( 6...b6 7.b4 ( 7.cxb6 { Best move } Nbd7 8.Bd2 Qxb6 9.Na4 Qa7 10.Rc1 { White has a lot of piece activity on the queen side. } c5 11.Be2 Be7 12.O-O c4 13.b3 cxb3 14.axb3 O-O 15.Ba5 { We have ideas of b4, Rc7, Nc5. White is very active. Bc8 is the bad bishop for black and it's very hard to exchange it. In the game black is succeeding to exchange the bad bishop from c8 } ) a5 8.a3 axb4 9.axb4 Rxa1 ) 7.b4 b6 8.Bb2 a5 9.a3 { b4 is reinforced that means that c5 will life } Be7 10.Bd3 O-O 11.O-O Ba6 { Black is playing with a space deficit, but his able to exchange his bad bishop with the good bishop of the white side } 12.Ne1 { Preparing to capture with the night. d3 square is a nice square for the night, but black can strike to the center by playing e5 but this is leading to big complications and an unbalanced position } Bc4 ( 12...e5 13.Bxa6 Rxa6 14.b5 cxb5 15.c6 Nb8 16.dxe5 Ne8 ) ( 12...Bxd3 13.Nxd3 Qc7 14.Qe2 Qb7 15.f3 axb4 16.axb4 Rxa1 17.Rxa1 Ra8 18.Rxa8+ Qxa8 { Black is benefiting after all these exchanges } ) 13.Bxc4 { Black bishop MUST be capture if not black will play b5 having double protection of the bishop } dxc4 { Black has a passed pawn and it can be also protected by b5, D file is opened, white has a 2(e3, d4) to 1(e6) pawns majority in the center } 14.Qe2 Rb8 { Indirectly defending the pawn because in the end Bb2 will fall } 15.Ra2 ( 15.Qxc4 bxc5 16.bxc5 Rxb2 ) b5 { Queen side is locked and black has protected passed pawn. In this game rooks are a problem for black and don''''t contribute to this game at all and this is due to move 12... Bc4. In order to save the pawn black is closing the position. Where do we proceed from here? This is an important position of this game. If black wants to exchange pieces he has to play 12... Bxd3 } 16.e4 { This is a very important move to play right now. There are other things that white can do regroup the rook from a2 it''''s no longer require to watch over Bb2. Regroup the night to c2 } ( 16.Ra1 { If we play a passive move black will take advantage and try to exchange pieces like Nd5. That''''s why we have to control d5 square by playing e4 then do the Ra1, Nc2 or Bc1 rerouting the bishop to h2-b8 diagonal } Nd5 ) Rb7 { preparing to come on the D file double the rooks. Another thing is that the night will reroute to b8-a6-c7 and watch over the d5 square. If white plays e5 then night will jump to d5 square } 17.Nc2 Nb8 18.Raa1 Qc8 19.Rad1 Rd8 20.Bc1 Na6 21.Bf4 Rbd7 22.h3 Ne8 { This allow bishop to go to f6 and pressure d4 pawn } 23.Qe3 { preparing to go to g3 to watch over g3-b8 diagonal and g3-g8 line followed by Bh6 making black to play g6 and cause weakness on the dark squares. Nc2, Nc3 and b4 pawn are controlling the entry points (a1, a2, a3, a4, a5) on A file } Bf6 24.e5 { Is played with tempo. We give up d5 square and we have 2 pawns that are controlling d6 square } Be7 25.Ne4 Nac7 26.Nd6 Qa8 27.Qg3 Nd5 28.Ne3 Nc3 { Threatens e2 forking the king and the queen } 29.Rde1 Bxd6 { Black captures the night from d6 in order to play Ne4 } 30.exd6 Ne4 31.Qh4 Nd2 { Black is winning the exchange. The night moved from d5-c3-e4 with tempo and d2 } 32.Nd5 { Sharp move a discovered attack on Nd2. If Nxf1 we play an intermediary move Nb6 heating the rook and the queen } Nxf1 33.Nb6 Qa7 34.Rxf1 { Maybe it was better to take with the king so the rook can stay on the semi open file. Maybe the king want to stay away from any surprising checks } Nf6 { White can take the rook from d7 but it does not make any sense because the 2 rooks are not doing anything and the value of the night is very high } 35.Be5 { Putting pressure on the night and on g7 pawn indirectly } Nd5 36.Nxd5 { Not taking the rook because the rooks are not doing anything. The black night is an active piece and we have to remove it } exd5 ( 36...cxd5 { This is not good because white has 2 passed pawns } ) 37.Bxg7 Kxg7 { White is down a full rook but the 2 rooks and the queen are not doing anything } 38.Qg5+ Kf8 39.Qf6 { White threatens Qh8# } Kg8 40.Qg5+ Kf8 41.Qf6 Kg8 42.Re1 { Preparing a rook lift } axb4 43.Re5 { Best move } ( 43.Re3 Qxa3 44.Rg3+ Qxg3 45.fxg3 { Black has 2 passed pawns and he wins the only way is to give a perpetual check } ) h6 44.Rh5 ( 44.Qxh6 { Bad move } f6 { queen and rook are able to defend from lateral } ) Qxa3 45.Qxh6 { Right move threatening Qh8# } ( 45.Rxh6 Qc1+ 46.Kh2 Qxh6 47.Qxh6 ) f6 46.Qxf6 { Aronian resigns due to Rh8# } Rg7 47.Qxd8+ Kf7 48.Qe7+ Kg8 ( 48...Kg6 49.Rg5+ Kh7 50.Qxg7# ) 49.Qe8#1. d4 d52. c4 c63.
