Nicol David - who is currently based in Amsterdam where she trains with Dutch national coach Liz Irving, the former world No2 from Australia - now faces top seed Cassie Jackman, the England No1 who crushed Ireland's Madeline Perry 9-4 9-1 9-0. The other semi-final will also be an Anglo-Malaysian affair - between sixth seed Sharon Wee, currently the highest-ranked Malaysian in the world, and England's third seed Vicky Botwright.
