Section 3: Playing Area
The Baulk-line and Baulk. A straight line is drawn 29 in (737 mm) from the face of the Bottom Cushion, running parallel to it from side cushion to side cushion; this is the Baulk-line, and the intervening space nearer the Bottom Cushion is termed Baulk (Section 1, Rule 1(d)).
The "D". A semi-circle is marked within Baulk, with the centre of its straight section at the middle of the Baulk-line and a radius of 11½ in (292 mm) (Section 1, Rule 1(e)). At the start of each frame, and whenever the cue-ball is "in-hand," it must be played from a position on or within the lines of the D (Section 3, Rule 5).
Spots. Marked at each corner of the D, the spot on the right (viewed from the Baulk end) is the Yellow Spot and the one on the left is the Green Spot. Four further spots sit on the table's centre longitudinal line: the Brown Spot, in the middle of the Baulk-line; the Blue Spot, midway between the points on the Top and Bottom Cushions perpendicular to it; the Pink Spot, midway between the Blue Spot and the point on the Top Cushion perpendicular to it; and the Black Spot, 12¾ in (324 mm) from the point on the Top Cushion perpendicular to it (Section 1, Rule 1(f)).
Pockets. There is a pocket opening at each of the four corners of the table and one at the middle of each of the two longer sides, giving six pockets in total (Section 1, Rule 1(g)).
Setup. At the start of each frame, per Section 3, Rule 2(a), the 15 Reds are positioned in a tightly-packed equilateral triangle with the apex Red set above the Pink Spot, as close to the Pink Spot as possible without touching it, and the base of the triangle parallel to the Top Cushion. The six colours are placed on their designated spots as described above.
