A review of ChessBase Magazine #214, June 2023, was published on the web site of the German company on September 7, 2023. Among the many topics of interest, one should mention a deep study of the last World Chess Championship match which culminated in the historic victory of 丁立人 (Dīng Lìrén) over Ian Alexandrovich Nepomniachtchi. No wonder, therefore, that four-time Women’s World Chess Champion 侯逸凡 (Hóu Yìfán) annotated, with her customary thoroughness and objectivity, the final crucial tie-break game:
Ian Alexandrovich Nepomniachtchi – 丁立人 (Dīng Lìrén)
World Chess Championship 2023; tie-break game 4; time control: 25 minutes plus 10 seconds per move; Astana, April 30, 2023
8/6pk/5r1p/p1pQ4/1b6/4B1PP/4qP2/2R3K1 w - - 10 46
46. Qe4+. An historic moment! While most of the people are already expecting the next tiebreak mini-matches, 丁 (Dīng) decides to fight for a win. Practically, it’s a nice test, as both were under very few minutes, and Nepo probably already expected a draw. With such mindset, things may go wrong as what happened in the game.
46. ... Rg6!? 47. Qf5?! Now things have started to go wrong. 47. h4 was more precise: 47. ... a4 (47. ... h5 48. Rc2 Qd1+ 49. Kg2 Qd6 50. Qf5 — Too many weaknesses for Black to protect) 48. Qf5 Qg4 49. Qc2 It is impossible for Black to keep both passed Pawns on board while stopping the h4-h5 threat.
47. ... c4! 48. h4? Towards the wrong side. 48. Qf4 was the only way to prevent the Black Queen from taking over the b1-h7 diagonal: 48. ... c3 (48. ... Bd6 49. Qxc4 Rxg3+ 50. fxg3 Qxe3+ 51.

48. ... Qd3−+. Now it’s a clear win for Black.

59. Qc7? Missing the final chance of the match. Honestly speaking, under super high pressure, such move may occur with high probability. However, with a closer look one would understand, the key thing is to control the golden g6 square. 59. h5! Bf8 (59. ... a2 60. Qf7+−) 60. Qf7 Qd3 61. Bxc3! Qxc3 62.
