This was enough to make him the #3 seed for the series finals. Horsey started in fine form of 5 October 2006, with a century against Andrew Blades, followed the next day with another century. He completed a trio of centuries during his 6th game, at the expense of David Price.
Horsey faced Joy Longworth in the quarter-finals, winning 76 – 69 despite Longworth getting the conundrum. This booked a semi-final spot against Richard Brittain. With Horsey trailing by 8 points going into the crucial conundrum, he needed to unscramble MARYSFOOT to progress. However, neither player could find STYROFOAM in the time, giving Brittain the final berth 83 – 75.
