comment: Ding has never played this before. With this move he shows that he wants a position without much theory and without many risks for this game.
context: 1. g1f3 Historically Ding’s main move is 1.d4. In his first white game he went for 1.e4. Now he tries a third option. 1... d7d5  2. e2e3  2... g8f6
