There's no need to hurry to capture the knight.
1. c2c4  1... g8f6  2. g1f3  2... e7e6  3. b1c3  3... d7d5  4. e2e3  4... c7c5  5. d2d4  5... a7a6  6. c4d5  6... e6d5  7. g2g3 [%c_effect g3;square;g3;type;Inaccuracy;persistent;true] In the post-game interview, Carlsen said that he doesn't understand why players keep choosing this line, as he thinks it's very comfortable for Black to play. In light of these words, I guess I have to label 7.g3 as a dubious move. It's hard to argue against Carlsen's chess understanding. 7... c5c4 [%c_effect c4;square;c4;type;GreatFind;persistent;true] Carlsen has experience with this move. He has won all the games he has played in this position. 8. f1g2  8... f8b4 This is a great square for the bishop. This piece is ready to capture the knight on c3, if necessary, followed by a knight jump to e4. 9. e1g1  9... e8g8  10. f3e5  10... f8e8  11. c1d2  11... b8c6  12. a2a3 A new move.
