Our earliest database example is when Cho Hye-yeon played it in a very similar position against An Tal-hun on 16 August 2004 in the 15th BC Card Cup. She won.
Having had this move played against it by Chang Hao, Ch'oe Ch'eol-han tried it himself very soon after, exactly as here, on 19 January 2005 in the 24th KBS Cup against Yi Yeong-ku. Ch'oe lost again.
