O Yujin has an agressive style, but she prefers to build up thick positions, biding her time to attack. She admires Lee Sedol’s creativity. She would like to reach the top 100 in the world of either sex. But [ext] she says:

I think female players are a little behind male players in terms of concentration and stamina.
