So quickly banged out his next couple of moves. The threat is  e4-e5.
1. g1f3  1... d7d5  2. d2d4  2... g8f6  3. c2c4  3... e7e6  4. g2g3  4... d5c4  5. f1g2  5... f8b4  6. c1d2  6... a7a5  7. e1g1  7... e8g8  8. b1a3  8... b4a3  9. b2a3  9... b7b5  10. d1b1 All of this has been seen so far with  Carlsen uncorking novelty now. 10... c7c6 Which is a generally  useful move. The long diagonal is blocked, the seventh rank opened for the queenside rook and Black does not yet determine his bishop position.
