12. Ng5. It is just a little tactic. 12. exd5 was probably preferable. 12. ... Bxg5 13. Bxg5 f6. After 13. ... Qxg5 14. exd5 and White will regain the piece with equality. 14. Be3? It’s amazing how little it takes for White to be inexorably crushed. 14. Bd2 at once was much better.


14. ... d4! 15. Bd2 b5 16. Rfc1 Qd6 17. Bf1 Rac8 18. Qe1 a5 19. a4 dxc3 20. bxc3 b4 21. Be3 Rfd8 22. Rc2 f5 23. f3?! ⌓ 23. f4 seems to make a little more sense, even though Black would play 23. ... fxe4 24. dxe4 c4 anyway, with great superiority. 23. ... fxe4 24. dxe4 c4 25. cxb4? A ruinous error, which loses immediately, but by now White had very little hope of stopping the avalanche — for instance: 25. f4 b3 26. Rf2 Nb4! and there’s a roller coming.


25. ... Nd4!−+ 26. Rf2 axb4 27. f4 c3 28. Rc1 Bg4 29. Kg2 Qc6 30. Bd3 Nb3 0 : 1.

  1. In his report for ChessBase India, Shahid Ahmed writes that "Pragg punished IM Volodar Murzin for passive play. White had to take on d4, 15.cxd4 Nxd4 is still good for Black. 15...b5 16.Rfc1 Qd6 17.Bf1 Rac8 18.Qe1 a5 and Black just rolls all his pawns down the board, eventually forcing White to resign after 30th move." -- see https://chessbase.in/news/Julius-Baer-Challengers-Chess-Tour-Hou-Yifan-Challenge-Day-2-report
