1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... f8c5  4. d2d3  4... d7d6  5. c2c3  5... c5b6  6. e1g1  6... g8f6  7. a2a4  7... a7a5 The combination of the moves a7-a5 and Bc5-b6 does not seem logical, but it took Sindarov by surprise, and he spent a bit more than half an hour on the clock for his next move. 8. c1e3 Now White reaches the position above, but with an extra tempo (see move 3). 8... b6e3  9. f2e3  9... e8g8  10. b1d2  10... c6e7 Concretely a novelty, but not a new maneuver at all. 11. f3h4 White's plan is very typical—bring the queen to the g3-square, jump to f5 with the knight, and/or sacrifice an exchange on f6. The question is, does he have time for all of this $2 11... d6d5 An instant reaction in the center. Black definitely needs to create counterplay asap.
