context: 1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. b1c3  3... f8b4  4. d1c2 One of White's most solid options against the Nimzo-Indian. 4... d7d6 Probably an indication that Abdusattorov was playing for a win. In the main variations with 4...0-0, the theory is very developed, and it can be difficult to find an idea to unbalance the game. 5. e2e3  5... e8g8  6. f1d3  6... c7c5  7. g1f3  7... b8c6  8. e1g1  8... b4c3 Usually after castling in these types of positions, it's a good idea for Black to take the knight on c3, since without the pin there's always the risk of the knight coming out and the bishop being badly placed on b4. 9. c2c3  9... d8e7 This is inaccurate. 10. d4c5 I like this decision a lot. White is heading for a position with a small advantage, reducing Black's active possibilities.
