Strategy

A successful pétanque team has players who are skilled at shooting as well as players who only point. For obvious reasons, the pointer or pointers play first – the shooter or shooters are held in reserve in case the opponents place well. In placing, a boule in front of the jack has much higher value than one at the same distance behind the jack, because intentional or accidental pushing of a front boule generally improves its position. At every play after the very first boule has been placed, the team whose turn it is must decide whether to point or shoot. Factors that count in that decision include:
How close to the jack the opponents' best boule is,
The state of the terrain (an expert pointer can practically guarantee to place within about 15 centimeters if the terrain is well tended, not so if it's rocky or uneven), and
How many boules each team has yet to play.
A team captain, in an idealized game, requires his pointer to place a boule reasonably close in approach to the jack (paradoxically, in competition, the first pointer sometimes aims not to get so close to the jack that the opponents will inevitably shoot their boule immediately). They then visualize an imaginary circle with the jack as its centre and the jack-boule distance as radius and defend that circle by any legitimate means.
