A new move.
1. d2d4  1... g8f6  2. g1f3  2... d7d5  3. c1f4 The long-awaited moment has arrived when the London System makes its first appearance in a world championship match. If I have criticized London players, here I demonstrate my complete regret for doing so. This is not a very common weapon in Ding's repertoire, but he has used it before, and Nepomniachtchi said he expected it at some point. 3... c7c5  4. e2e3  4... b8c6  5. b1d2  5... c5d4  6. e3d4  6... c8f5  7. c2c3  7... e7e6  8. f1b5 Not the most popular choice. 8... f8d6  9. f4d6  9... d8d6  10. e1g1  10... e8g8  11. f1e1 There are not many games in this position, and most of them are by GM Gata Kamsky, a great expert in the London System. The position looks calm and even monotonous; it is difficult to predict the fireworks that we will see later. White's plan is to try to exert some pressure on the queenside, advancing the a-pawn and trying to get the knight to c5. Black's position is very solid, but there is no clear game plan. 11... h7h6 A useful move, giving the bishop a square and the king some air. However, due to White's next move, this move may not be the most accurate.
