This is the move of choice if Black doesn't want to sharpen the game with g7-g5. 7. h4g3  7... d7d6  8. a2a4  8... e8g8 Caruana deviates from the game he played in the recent Grand Swiss, although the ideas remain similar. 9. a4a5  9... a7a6  10. b1d2  10... c8e6 There are many possible plans for Black. 11. c4e6  11... f7e6  12. e1g1  12... f6h7  13. c2c3  13... h7g5 Only now Caruana started to think.
