In snooker, when potting the colours in sequence, between which balls should the brown be potted?

Snooker is a cue sport that originated among British Army officers stationed in India in the second half of the 19th century. It is played on a rectangular table covered with a green cloth (or "baize"), with pockets at each of the four corners and in the middle of each long side. Using a cue stick and 21 coloured balls, players must strike the white ball (or "cue ball") to pot or pocket the remaining balls in the correct sequence, accumulating points for each pot. An individual game (or frame), is won by the player scoring the most points.

The aim is to pot one of the red balls into a pocket and thereby score a point. If a red ball is potted, you must then pot one of the six "colours". If the player successfully pots a colour, the value of that ball is added to the player's score, and the ball is returned to its starting position on the table. After that, the player must pot another red ball, then another colour, in sequence. The game continues in this manner until all the reds are potted and only the six colours are left on the table. The coloured balls must be potted in the order from least to most valuable ball. The shots are: yellow first (two points), then green (three points), brown (four points), blue (five points), pink (six points) and black (seven points), the balls are not returned to play. When the final ball is potted (the black), the player with the most points wins.
