Chitra made her intentions clear with a well thought out game plan in the first frame and continued till she lost out on the black ball in the second.
However, in the third and fourth frame, Belgium's Wendy played a different ball game bagging the latter with a break of 59 and not giving a single red to Chitra.
Wendy continued her imposing game pocketing the fifth frame with minimal fuss.
Earlier, Chitra had beaten compatriot Varsha Sanjeev in the last-eight stage.
