Nepomniachtchi is OK with the doubled pawns.
1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5  3... a7a6  4. b5a4  4... g8f6  5. e1g1  5... f8e7  6. d2d3 A modest, solid line. White often plays like this when he wants to avoid the Marshall  Gambit. 6... d7d6  7. c2c3  7... e8g8  8. b1d2  8... f8e8 A standard regrouping that aims  at the center. 9. f1e1  9... e7f8  10. d3d4 White gains control of the center, but  this comes with a price. 10... b7b5  11. a4c2  11... e5d4  12. c3d4  12... c8g4
