She was also Estonian rapid chess champion six times (for U18 girls in 2001-2005 and for U18 in 2007) and junior team champion for boys (2003) and for girls (2003 and 2004). In six of those tournaments she obtained 100% score by winning all the games. She was awarded the Woman Grandmaster title in
Antalya in November 2007, thanks to her results at the Mediterranean Flower WGM Tournament in
Rijeka 2006 and at the
European Women's Championship 2007 in
Dresden, Despite having lived all her life in Estonia, Valentina Golubenko and her parents decided to hold Russian citizenship. Golubenko's family claims that the decision of the Federation contradicts FIDE's General Rules for participation in FIDE events. Estonia's leading grandmaster
Jaan Ehlvest agrees with this opinion. As a solution, the Estonian Chess Federation proposed Golubenko to apply for Estonian citizenship; this proposal was rejected by the Golubenko's family. ==Career in Croatia==
