By winning game 4 of the rapid tiebreakers — after three draws — Ding Liren became the 17th undisputed world chess champion! Ian Nepomniachtchi seemed to have things under control in the deciding game, and even a bit of an advantage at times, but he overestimated his chances and allowed Ding to get a dangerous passer. Ding kept his nerves and converted his advantage brilliantly. | Photo: FIDE / Stev Bonhage
