"I am very happy to become Goa's first Woman Grandmaster," an elated Bhakti said.
"It's a dream of every chess player to achieve this feat and I am glad that I could finally do it.
"I will now strive hard to achieve IM (International Master) and IGM (International Grandmaster) titles," Bhakti said.
