He was on course to even wrest the fourth game after he compiled a wonderful effort of 101, but a costly lapse by him gave a window of opportunity to Advani.
Composing himself, in a superb rally the maestro chalked up a classy break of 127 to snatch the game and draw level once again at 2-2.
Then Advani struck a purple patch, cajoling and nursing the balls at the top of the table to craft identical unfinished breaks of 150 in the fifth and sixth games to run up a crucial 4-2 games lead.
Not giving up, Sitwala put up a tremendous show of skill, patience and temperament to strike a break of 134, but sadly, when in prime position he could not hold the balls together to give another chance to Advani after a sequence of safety exchanges.
