Woods has opened up a three-shot lead over the field after again getting the most out of the front nine and finishing yesterday 10 under par.

Those trying to reel him in admit they have their work cut out.

Leading the hunt will be Australia's Greg Chalmers, who was only two shots behind until he bogeyed the 17th hole, along with Newcastle's James Nitties and American Jason Dufner who are tied for second on seven under.

Kingston Heath is expected to get firmer and trickier with warmer weather and winds expected this weekend.

So, with a three-shot lead going into the final 36 holes, can Tiger even be caught?

''I think as a professional you have to believe so, otherwise you may as well just throw the sticks in the bin and go home,'' Chalmers said.
