Last year she faced a torrent of criticism for her apparently deranged tactics and interactions with other runners that had negative results for her as well as competitors, surging, bumping, striking etc. Resulting in championship failure.
This time she seized the lead immediately and ran them all into the ground .....steadily and unstoppably running away from her rivals in a way that must have made Jakob hard when he watched the race. She did exactly what he wants to do and made it work. Bell and Welteji immediately yielded to her and accepted racing for the minor medals by 400.
Id say she employed best tactics of the championship.
