comment: A solid choice, but the alternatives are interesting.
context: 1. g1f3  1... d7d5  2. g2g3  2... c7c5  3. f1g2  3... b8c6  4. d2d4 Another new opening in the match. 4... e7e6  5. e1g1  5... c5d4  6. f3d4  6... g8e7 A rare move. As usual, Gukesh demonstrates a new idea early in the game. This time, however, it will backfire—White will achieve a pleasant position. Black's idea is to exchange on d4 and get the knight to c6. The downside to this strategy is that Black's king can be a bit unsafe in some positions without the knight nearby, although this may seem far from reality at the moment. 7. c2c4 The best reaction, attacking the center. 7... c6d4  8. d1d4  8... e7c6 Black follows the planned strategy. Now White has several possible queen moves.
