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. 12... b4a5 There's no need to hurry to capture the knight. 13. b2b4
