Higgins started brightly and although Robertson had the first opportunity, it was the Scot who took the first frame thanks to an earlier break of 66 which immediately set the quality of the match.
The World number four looked to have doubled his lead with a break of 62 in the second but was powerfully overshadowed by Neil Robertson who made the highest break of the match so far with a well crafted 80 to level the match.
The third and fourth frames were both very tight affairs, with both players having strong chances to take both frames, but it was John Higgins who took them both and moved two clear of his opponent to set an early score line of 3-1.
Higgins created a three frame advantage just before the mid-session interval thanks to a break of 68 but Robertson pegged the Scot back to just two after the re-start with two sizeable contributions of 40 and 41.
The left-hander started to find his feet and although it eventually took him three bites at the cherry and was gifted four points thanks to a foul by Higgins, Robertson came within one frame of levelling the match at 4-3.
John Higgins responded like all great players should in a scrappy frame with both players producing numerous unforced errors, but it was the Scot that stole the longest frame of the match so far and in doing so takes a two frame lead into tomorrows conclusion.
