International Master Dronavalli Harika held Armenian Grandmaster Hrant Melkumyan to a draw, while compatriot Tejas Ravichandran's dream run was halted by Grandmaster Ghaem Maghami Ehsan of Iran in fourth round of the 12th Dubai International Open Chess tournament here.

Harika played solidly with white pieces to keep the aspirations of Melkumyan at bay in a King's Indian defense game and the Armenian could do no better than holding on to an equal position in a keenly contested encounter.
