4... exd5 Magnus took the pawn 4.cxd5 with obvious intention to avoid Lasker Variation which has big drawish tendences.Rememer,for example, the Candidates Match Kramnik-Radjabov
5. Bf4 c6 6. Qc2 Bg4 The idea behind 6....Bg4 is to prepare light squared Bishops exchange Bg4-h5-g6 if White develops his Bishop to d3. Few games on high level with this live, White's main options are : 7.e3 and 7.f3, the second option is more agressive followed by O-O-O and e2-e4, for example Shirov plays it. Shirov - Spraggett in 1990 was : 7.f3 Bh5 8.O-O-O Nf6 9.e4 Bg6 10.Bd3 O-O 11.e5 with good chances for White which Alexei converted into a victory. Another option for White is 7.e3 which is extremely solid comparing with 7.f3. After 7.e3 Black can play 7....Bh5 with the idea to exchange Bishops after 8.Bd3 Bg6. The most common plan for White in Carslbad structure (which we already have on the board) is a pawn minority attack like Ra1-b1,b2-b4-b5 with the idea to create Black's pawn weaknesses on the queenside. While Black has to look for counter on the kingside or prepare c6-c5 when White plays b2-b4-b5
7. e3 Bh5 8. Bd3 Bg6 9. Bxg6 hxg6 10. O-O-O A novelty by Carlsen, 10.f3 and 10.Nf3 are other moves tried, but obviously Magnus chose the most agressive weapon. His idea is to attack Black's King on the kingside by "g" and "h" pawns promotion if Black castles short. As an alternative,White can look for play in the centre,for example,preparing e3-e4 promotion, but let's not forget that Black can castle long. Black's long castle in Queen's Gambit Declined is a normal thing but in this position it will be more difficult to do as White has a Bishop on f4 so Black will not have Kc8-b8-a8 idea.

10... Nf6 11. f3 Nbd7 12. Nge2 12.Nge2 is a flexible move,White develops a piece and doesn't show his cards yet having at his disposal both ideas e3-e4 and g2-g4 promotion. I guess,if Black's King stays in the centre White will push e3-e4 and when Black makes a short castle,Magnus will make g2-g4 with following h2-h4-h5
12... b5 a little bit dubious decision by Black as Naka starts the attack with his own King in the centre
13. e4 Magnus' reply looks obvious - a central promotion 13.e3-e4. Black weakened his queenside : now the pawn c6 and c5 square are weak. Black will have to suffer by dynamical play, as positionally he is worse.
13... b4 14. Na4 dxe4 15. fxe4 Qa5 we can already evaluate the position after the opening outcome. White got better position as now Magnus has a strong pawn centre,safe King and nice developed pieces, while Black has many pawn weakness and uncastled King. For sure, in the next moves Black will look for agressive counter to compensate positional weaknesses.
16. Kb1 As we can see from the move 16.Kb1,Magnus wants to stabilize his position. An interesting choice by White!The real idea of Magnus was to safe his King and start an attack. Now the question is who will be faster with the attack. White relies on h-pawn while Black has to prepare c6-c5 promotion.
16... O-O 17. h4 Rfe8 Black wants to liberate f8 square for the Knight to defend the King
18. e5 Nd5 The main question of the position is will Magnus win with the direct attack or not? 19.h5 looks natural,opening h-file. Black will start looking for counter with some sacrifices like b4-b3 but I'm not sure that it's sufficient
19. h5 g5 Black doesn't want to open h-file,so Naka plays 19...g5 but now White has at his disposal an interesting break : 20.h6 g6 21.e6 and Black has serious problems on the kingside
20. h6 g6 21. Bc1 Carlsen preffers to avoid complications and just returns with the Bishop intenting to play e5-e6 the next move
21... N7b6 22. Nc5 Bxc5 White has to change his plan all the time after Black's move,now after 22..Bxc5 the key point will be dark squares,especially the diagonal a1-h8, as Black exchanged his Bishop which was defending dark squares.
23. dxc5 b3 24. Qxb3 Qxc5 Now 25.h6-h7+ seems to be logical to prevent Kg8-h7 by Black
25. Nd4 White sacrifices a pawn on e5 with the idea to open a1-h8 diagonal.
25... Rxe5 26. Nf3 Re2 27. Nxg5 Qe7 White now has a big advantage, but at the moment there are not direct ways for win. Concetration and precise calculation is needed for win.
28. Qd3 Rf8 29. Rdf1 White is preparing a sacrifice on f7, so a move with f-pawn for Black is needed. All White pieces are placed greatly, so that Black can't exchange Queens and create an attack.
29... f5 30. g4 Na4 Even 31.Ka1 seems to be logical to prevent any kind of Black's counterplay
31. Qd4 Magnus wanted to win immediately with h6-h7+ but unfortunately Black can close the diagonal by Qe7-e5. Carlsen just wanted to exchange Queens and keep the attack, after queens exchange Black wouldn't have any counter.
31... Qe5 32. Qxe5 Rxe5 33. gxf5 gxf5 34. Nf3 Re7 now white can win the exchange after after 35.Rfg1+ Kh8 36.Rg7! or 36.Nh4. Black's Knights are too far away from the kingside so Black has to lose material.
35. Rfg1+ Kh7 36. Rg7+ Kh8 37. Rhg1 Rfe8 38. Nh4 Rxg7 And Carlsen won the game! Thank you for following with me GM Ipatov. Expect videos later today from GM Danielsen. See you tomorrow for more live analysis on ChessBomb.com and Chessdom.com! 1-0
