In round 10, Ding Liren scored a second consecutive win by beating Richard Rapport with the black pieces. In the endgame, he had the more active king and that proved to be the crucial factor to decide the winner of the encounter.
Rapport gave up the exchange with 45.Rxd4 (also allowing his king to escape via g1), but even the opposite-coloured bishop ending is lost for White as the black king will quickly invade on the queenside.
Round 12 saw Alireza Firouzja holding a draw with black after some adventurous play against Jan-Krzysztof Duda. But how could have Duda got better winning chances in this position?
37.Rxf7 was not precise. Keeping more tension in the position with 37.Rfg2 would have given White good winning chances.
