Definition:Hawk-Dove

Definition
Hawk-Dove is an instance of a class of games whose mechanics are as follows:

There are two players: animals fighting over some prey.

Each can either behave like:
 * a dove, in which they cooperate and share

or:
 * a hawk, in which they fight for full control.

If they both act as doves, they both obtain a goodly part of the prey.

If they both act as hawks, they lose control of the prey, and the latter escapes, so they receive nothing.

If one acts as a hawk and the other as a dove, the hawk controls the entire prey, granting the dove some small portion.
