An interesting property of Pikemen is the dichotomy between attacking and defending. An attacking piece has very little defensive value, since any other piece can capture it, yet it must become vulnerable in order to threaten an opponent's pieces. A defending piece, being upright, cannot attack at all, but can only be captured by a limited number of pieces; 3-point pieces cannot be captured at all while upright. A player who creates a strong attack formation will be exposed to counterattacks, and a player who plays very defensively will be slow in acquiring points. This creates an interesting balance between aggressive and cautious play styles.
A common and obvious strategy in Pikemen, as well as Chess, is pinning. An upright piece cannot be reoriented if it is being pointed at by another piece, lest it be captured. A 3-point piece can be immobilized by a 1-pointer, but only as long as the 1-pointer is there. Pinning is commonly resisted via counterattacking the pinning piece.
It gives you a definite advantage to have as many 3-pointers mobile as possible. The game is all about points, and 3-pointers are the best way to rack up points. Each pinned 3-pointer is diminished in its ability to apply offensive pressure to your opponent.
