Nicholas played a sterling middle and endgame to make critically important moves, just enough to make the difference between winning and losing a game.
With this win, Nicholas won 2.5:0.5 points over Yee Weng, making the fourth game superflous. This pushes Nicholas into the Malaysian Masters Final meeting the waiting IM Mas Hafizulhelmi, the other finalist, in 18-20th December 2009.
