[#] 12... d7d5 After thinking for 11 minutes, Nepomniachtchi fires a  novelty, but Giri is not impressed at all and keeps blitzing on! 13. b2b3  13... f8b4 After another lengthy deliberation by the Russian GM. 14. b3c4  14... a8a3  15. f4e5  15... f7f6  16. e5d4  16... b6a5  17. f1e2  17... b4c3  18. c1c3  18... a3c3  19. e1f1  19... b5b4 The mark comes predominately for the practical strength of  the move. But having a strong passer on c3 does not look bad either! Giri  knew this move too, but he believed it to be highly unlikely to be played  as both c4 captures look logical and are, in fact, good too. 20. g4g5 Finally, some thought by Giri. 20... e6e5 The point behind  Black's last move. Nepomniachtchi secures his king and himself from any  homemade bombs. 21. d4c3  21... b4c3  22. g5f6  22... g7f6  23. d1b1 Giri is still playing for more than  the position offers him and will be soon sorry.
