This leads to a very dangerous position for Black after Firouzja's next move.
1. g1f3  1... d7d5  2. c2c4  2... d5d4  3. b2b4  3... g7g5 A bold move, that's for sure. 4. h2h3 A good and solid reply. 4... h7h6 The pawn must be defended sooner or later. 5. d2d3  5... f8g7  6. g2g3  6... e7e5  7. f1g2  7... g8e7 Black's plan is to castle and play f7-f5 - his position is very active. 8. b1d2  8... e8g8  9. d1b3 A new move. 9... c8e6 Considering what happens in the game, maybe it was safer for Black to play either 9...f5 or 9...Ng6, with a good position in both cases. 10. d2e4  10... b8d7  11. g3g4 Otherwise Black simply plays f7-f5.
