All this is already well-established by opening theory. 10. b2c3  10... e8g8  11. f3e1 An interesting move, much less played than 11.Nb3. 11... c8d7 Arjun was probably surprised by White's last move since he responded with an inaccuracy. It's important to keep the pawn on b7 defended for now. Both 11...Rd8 and 11...Be7 are better. 12. a1b1 It's not easy for Black to protect the b7-pawn. The problem is that b7-b6 is tactically refuted due to the loose placement of the bishop on d7. 12... c6a5  13. d2b3 Forcing the exchange of knights, after which the pawn structure is improved. 13... a5b3  14. a2b3  14... d7c6  15. g2c6  15... b7c6  16. e1d3 The opening is a success for White, with a comfortable advantage in a risk-free position. 16... c5e7 A new move. 17. c1e3  17... f8c8  18. e3c5  18... g8f8  19. b1a1  19... c8c7  20. g1f1
