PETALING JAYA: Women’s doubles shuttlers Pearly Tan-M. Thinaah had been trying every trick in the book to overcome new pairings formed after the Paris Olympic Games but without any success.

Yesterday though, world No. 4 Pearly-Thinaah cracked the code when they pulled off an impressive 21-14, 21-11 win over China’s new combo Chen Qingchen-Wang Tingge to reach the Thailand Open semi-finals.
