context: 1. g1f3  1... d7d5  2. c2c4  2... d5d4  3. b2b4 Another different opening in a match in which the players don't want to repeat their preparation with White. 3... c7c5  4. e2e3  4... g8f6 Played after almost 40 minutes. 5. a2a3 A new move in this position, although I found one game that transposed to it. This game actually started with 1.a3 $1 5... c8g4 A new move that cost Ding a lot of time on the clock. 6. e3d4  6... c5d4  7. h2h3  7... g4f3  8. d1f3  8... d8c7  9. d2d3 White needs to play incisively. The continuation of the game is slow and quickly leaves Black in a good position.
