Teimour Radjabov continued to torment Daniil Dubov by inflicting a 63-move defeat in the first game of the second set of their semifinal clash in the $200,000 Airthings Masters online rapid chess tournament on Friday.

A day after gaining from Dubov’s oversights and winning twice to take the first set 3-1, Radjabov patiently capitalised on an early pawn-gain and scored a third win in the contest.

In the other semifinal, Levon Aronian started the second set with a draw against Maxime Vachier-Lagrave. On Thursday, Aronian continued his relentless form seen against Hikaru Nakamura in the quarterfinals,
by defeating Vachier 3-1 in spite of losing a knight for nothing in the final game.
