Robert Blair and partner Gabby White are through to the second round of the Li Ning Singapore Open, but Imogen Bankier and Chris Adcock lost in the first round.
Scotland's Blair and England's White beat Canadian pair Toby Ng and Grace Gao 21-13 21-13.
They now face Thailand's Sudket Prapakamol and Saralee Thoungthongkam in the second round.
It was the Thai pair who eliminated Bankier and Adcock 21-15 21-19.
Should Blair and White win in the second round they could face fellow Britons Nathan Robertson and Jenny Wallwork in the quarter finals.
Only eight ranking places separate the three British pairs vying for the Olympic mixed doubles place.
Robertson and Wallwork are ranked 15 in the world, with Adcock and Bankier at 20 and Blair and White 23rd.
