While 27-year-old Advani, the seven times World Champion, hammered compatriot Rupesh Shah 1,647-705, Sitwala edged out Sourav Kothari 558-562 in another all-India quarter-final.
Advani, who crafted two double centuries and four centuries, will take on Sitwala in the top-half of the draw while in the other semi-final reigning champion Mike Russell, who ousted Geet Sethi 1,345-739, meets Mathew Bolton who defeated David Causier 927-891.
“I am very happy to be playing fellow-Indian and a great friend in the semis. With two Indians at the table, we are guaranteed a spot for the country in the finals of the Time format and it also gives us a great chance of bringing the title home,” said Advani.
In the points format quarter-finals, top seed Advani went down 1-4 to Peter Gilchrist, who thus set up a clash with Rupesh Shah, a 4-2 winner over Ashok Shandilya.
The other semi-final will be between Bolton, who overcame Devendra Joshi 4-0, and Causier who ousted Martin Goodwill 4-1.
