Thus everything will depend now on Black. Will the temporary advantage in strength be good enough to ruin the center with breaks c7-c5 or f7-f6, or will White be quick enough to stabilize the position $2 9... e8g8  10. c1e3  10... c8f5 Completing development. 11. e1g1  11... e4c3 This is not the most common idea. 12. b2c3  12... f7f6 Black has no other plan. 13. d1d2 And Praggnanandhaa comes with a logical and strong novelty. The center is now overprotected and the rooks are connected. 13... f5e4 Murzin keeps fighting for the center. 14. b5c6 A key resource for White that not only provides enough control over the d4-e5 squares, but which also blocks the remaining black bishop. 14... b7c6 Following the forcing line. 15. e5f6  15... e4f3  16. f6g7  16... f8f7  17. g2f3  17... d8f6 It is important to bring the queen in. 18. f3f4  18... f6f5 Murzin in following his plan. 19. g1h1  19... f7g7  20. d2e2 Now White can claim a certain edge. 20... g8f7  21. e2f3  21... a8g8  22. a1e1 Praggnanandhaa has stabilized the position and Murzin is practically forced to go for 22... f5g4 The only chance. 23. f3g4  23... g7g4 White is clearly on top, but can he win this $2
