Therefore Nepomniachtchi hurries with his counterplay. 10... a7a5  11. b4b5  11... c6b4  12. c1a3 In return Dominguez seizes control of the  beautiful a3-f8 diagonal. Black's castling became close to impossible with the advance of the h-pawn, but the king would not be safe in the middle  neither. 12... b4d3  13. c2d3  13... c8d7  14. f4a4  14... e7f5  15. a1c1  15... g7g5  16. h2h3  16... a8c8  17. c1c8  17... d8c8  18. e1e2 This was why Dominguez postponed the  castling. The rook on h1 is preventing any play related to the g5-g4  break, while it is ready to shift to the queenside at once. Black might  still be OK, but the correct path became very narrow and he erred at once.  18... c8b8 In the search of counterplay Nepomniachtchi sends the  queen on a seemingly better working place. Unfortunately for him his  threats are not as strong as he thought. 19. d2b3  19... b8a7 The queen switches on the attack of the f2 pawn.
