1. d4 Nf6 2. c4 g6 {Offering a Kings Indian or Grunfeld} 3. g3 Bg7 4. Bg2 O-O 5.   Nc3 {Both sides have developed quickly and we have reached King's Indian   territory} d6 6. Nf3 Nbd7 {An interesting move, Black wants to advance either   the 'e' or 'c' pawn but without allowing a Queen trade} 7. O-O e5 8. e4 {   Nice move, in general neither side wants to break the central tension} Re8 9.   d5 {White blocks the centre and hopes to dominate with his extra space} Nc5 10.   Ne1 a5 {Another important move, making the b4 push more difficult to achieve}   11. Be3 b6 {Another defender for the Knight and a possible new diagonal for   the light squared Bishop} 12. f3 {another dual purpose move, e4 is protected   and the Black pieces are denied the g4 square, both sides are playing good   moves and showing understanding of the opening} Bd7 13. Qd2 Qc8 14. Nc2 {   Both players are looking for a pawn break but where will it come from?} Bh3 {   Nh5 looking to play f5 was better} 15. Na3 {Excellent move, White wants a   Knight on b5 but prefers to keep the more active horse on c3} Bxg2 16. Kxg2 {   White must stand better, as the light squares on the queenside will be excellent outposts} Qd7 17. Rad1 Nh5 {Very nice, Black is now ready for f5} 18.   Nab5 f5 {The game is going to get messy, the question is which King will be   the safest?} 19. exf5 gxf5 20. b3 {maybe a3 to threaten b4 was better} Rf8 {   my engine gives this as level, White has control of the queenside and Black   has open files on the kingside} 21. Kh1 {Nice, White anticipates the 'g' file   opening} Nf6 22. Qg2 Kf7 {I think the King would have been better on h8,   keeping the 'f' and 'g' files for his pieces} 23. g4 f4 24. Bxc5 bxc5 {White   is now better, the Knight on b5 is just annoying and the other is looking at   e4, Black needs to defend very well to survive} 25. g5 {Brilliant, White   forces the Knight back} Ne8 26. Ne4 Rg8 {Black can only wait for the attack}   27. Rg1 Bf6 {A clever move taking advantage of the pin} 28. Qf2 {A really   strong move, breaking the pin and giving the Queen entry on the dark squares.   Nxc7 was also found by the engine} (28. Nxc7 Qxc7 29. Qh3 Bd8) 28... Bd8 29.   Qh4 Qf5 30. Rg2 {looking to double Rooks, Rg4 was also good} Qg6 31. Qg4 {   White is winning, but, how does he break through?} a4 32. h4 h5 33. Qd7+ Kf8 {   Black has defended but is now very passive and can only await to see what will   happen} 34. Rdg1 Rg7 35. Qc6 Rb8 {The position is almost Zugzwang, probably   White can simply take on a4} 36. Nf6 {White made this move quite quickly,   possibly because his opponent was very short of time, but now Black has a way   out} Bxf6 37. gxf6 Qxf6 38. Rxg7 Qxh4+ {Chess can be cruel, for most of the   middle game the Black King was a target, now roles are reversed} 39. Kg2 Nxg7   40. Qxc7 Qg3+ {Black can now force a perpetual} 41. Kf1 Qxf3+ 42. Ke1 Qe3+ 43.   Kf1 Qf3+ 44. Ke1 Qe3+ 45. Kf1 Qf3+ 46. Ke1 {A really interesting game and both   players can take a lot of credit from it} 1/2-1/2   

   1. e4 e5 2. Nf3 Nf6 3. Nc3 {Carlsen   chooses to avoid mainline theory and just gets developed} Nc6 4. a4 {Again a   move to get So away from his preparation} Bb4 {A good move, the more so as   White can not play a3 to chase the Bishop away} 5. Bd3 {This looks strange but   of course So already has a piece on b4 so is not able to threaten the Bishop   on d3} d6 6. O-O O-O {Both players have castled, Carslen now looks to untangle   his pieces} 7. Nd5 Bc5 8. c3 {Carlsen is slowly improving his position, if he   can move the light squared Bishop and play d4 then So's kingside may come   under attack} a5 9. Bc2 Nxd5 {So captures to give himself some space but gives   Carlsen an important tempo} 10. exd5 Ne7 11. Ng5 {Where is the Knight heading,   e4 maybe?} h6 12. d4 {Interesting move, now both White Bishops are free and   Carlsen is looking to attack the King} Bb6 13. Nh7 {With a very original idea   to follow} Re8 14. Nf6+ gxf6 {The position is equal but much more fun to play   as White} 15. Qh5 e4 16. Re1 f5 {This looks sensible but in fact Carlsen is   now winning} 17. Bxh6 Nxd5 {Preventing the Rook lift to e3} 18. Bg5 f6 {   The final mistake, the rest is easy for Carlsen} 19. Bb3 {Pins the Knight and   more importantly allows the mentioned Rook lift} c6 20. Re3 Kf8 {Taking the   Bishop does not help} (20... fxg5 21. Bxd5+ cxd5 22. Qg6+ Kf8 23. Rh3 Be6 24.   Rh8+ Bg8 25.
