Looks like the reversal is likely to be from fear of legal challenge.
Initially, in August, with increasing numbers of trans players applying to play in women's tournaments, the WEPF had put out a joint statement with its main sponsor the Ultimate Pool Group ruling that 'these events will be exclusively open to individuals who are born female.'
But just eight weeks later there was a shock reversal in this decision, which a number of women players have suggested was made under pressure of legal threats from trans competitors.
This bit looks hopeful though. And notably women are increasingly using their name to speak out rather than being anonymous...
Within a week of this announcement more than 60 professional female pool players joined forces through a WhatsApp support group to oppose the changes, the Mail on Sunday has been told.
One player, Lynne Pincher, said: "when I heard the announcement last week I spent most of the day in tears, especially because it came after the announcement eight weeks earlier that it was finally going to be a fair field. I'm worried now about the future of the game for women. If next year we had eight trans players they would probably be in the top eight"
