Having fought back on two occasions in the first mini-session to be level at 2-2 Higgins then took control in the second.
The second mini-session was blighted by both players failing to finish off frames and letting their opponents back in.
In the fifth Higgins let Selby in only to then find himself back on the table as his opponent was unable to dislodge the reds that had nestled on the side cushion, and Higgins made no mistake this time as he took a lead for the first time.
The sixth took a while to get going but when Higgins did find himself amongst the balls he made it count, making a break of 95.
Selby was guilty of throwing away a frame in the seventh as he led 52-1 only to miss a red and see Higgins come back with a break of 58.
Then in the final frame before the break it had seemed as if Higgins had it all wrapped up but he missed a couple of pots and all of a sudden an epic safety battle unfolded, with Selby producing a sensational pot on the red.
