In the first set of the match between Magnus Carlsen and Levon Aronian on Thursday all four games ended in a draw. On Friday, they fought tenaciously. Carlsen won games 1 and 4.
Endgame expert Karsten Müller was most interested in game 3, however. In the rook ending a pawn down, Aronian proved to be a great defender.

In the Armageddon decider of the other semifinal, Alireza Firouzja had the black pieces and a single oversight cost him the game. A draw would have been enough for him, though according to the rules he entered this game with 4 against 5 minutes on his clock, a crucial factor in these encounters — especially when there is no increment.
