1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. b1c3  3... f8b4  4. e2e3  4... e8g8  5. c1d2 A fashionable variation in the Nimzo-Indian. You can check my analysis of Nakamura-Praggnanandhaa from the same tournament. 5... b7b6  6. f1d3  6... c8b7  7. g1e2 [%c_effect e2;square;e2;type;Interesting;persistent;true] The development of the knight on e2 in this line is somewhat surprising. 7... d7d5  8. c4d5  8... e6d5  9. e1g1  9... f8e8  10. a1c1 The game has transposed to a position that has been played by strong grandmasters a few times. 10... a7a6 A good move in order to play ...Bd6 without having to worry about Nb5. 11. f2f3  11... b4d6
