Moscow: Indian Grand Master Pentala Harikrishna registered his first win of the Moscow FIDE Grand Prix after he got better of English GM Michael Adams here.

The Hyderabadi playing with white pieces on Tuesday night took the aggressive route from the word go and the Englishman could not do much and wilted under the pressure to concede the game.

"After a few inaccurate moves in the initial stages of the game, Adams gave me a good position. From there on, I gradually improved my position and won," Harikrishna said after winning the tie.

With the win, the World No. 16 Indian now has maintained his unbeaten run against Adams this year and recorded his second successive victory against him.

With one win, three draws and a loss in five games so far in the campaign, Harikrishna has accumulated a total of 2.5 points and is placed 13th on the leaderboard.

After a day's break, Harikrishna will resume his campaign against Greek GM Boris Gelfland in the next round of this elite tournament, which gives the participants a chance to qualify for the Candidates Tournament.
