As always in the Italian opening, several move orders and alternatives are possible, although the game's character doesn't change much.
1. e2e4 Ding can play all three pawn moves (1.e4, 1.d4, and 1.c4), but opening with the king pawn was a bit of a surprise to me, as it's the one he plays the least. Furthermore, after his win with Black in the first game, one would expect him to avoid the sharp play resulting from a Sicilian defense, for example. But Gukesh decides to play solid, which is a good strategy after a loss. 1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... f8c5  4. d2d3  4... g8f6  5. b1c3 This is the first time Ding has played this move. It's White's third most popular choice. 5... a7a6  6. a2a4  6... d7d6
