Andy Souwer
In July 2004, Buakaw became the K-1 MAX World champion beating John Wayne Parr, Takayuki Kohiruimaki and previous champion Masato in the finals. In 2005, he nearly repeated his run for tournament champion but lost the extra round in a controversial decision to Dutch shoot-boxer Andy Souwer in the finals. In the 2006 K-1 MAX World Grand Prix, Buakaw again faced Andy Souwer in the finals but this time defeated Souwer by TKO with a flurry of punches; thereby winning his second K-1 World MAX title and becoming the first man to win such title twice.
