In the board game Go, a is a tactical situation where two adjacent groups of different colors battle to capture each other because there is not enough space for both groups to secure two eyes and become safe. One common outcome is that one group is captured, resolving the race. In the most simple situations it is possible to predict this result, by counting the liberties on each group: if for example there are four liberties each, the advantage will lie with the player able to play first, while if one side has four liberties and the other five, the result is already decided and neither player will continue (the player who is behind will normally leave the area alone, seeing it as a future source of ko threats). There are numerous other possible outcomes, for example a seki, a ko of a direct or indirect nature, and (rather rarely) more exotic types of repeating situation such as triple ko or chosei. In the more orthodox races some theory is available to help understand the status as far as liberties goes, when these are not obvious; but such theories are not so far able to give an exhaustive description of all capturing races.
