Temperature is a term imported from combinatorial game theory that refers to the urgency of a play. Hotter plays are more urgent[1] than cooler plays. Temperature is related to several common Go terms. Generally, the temperature of the whole board, or simply, the temperature, corresponds to the size of the largest play. As the game progresses, the temperature tends to drop. The local temperature corresponds to the size of the largest play in a region of the board. Generally speaking, a gote play lowers the local temperature and a sente play raises it, while if the local temperature stays the same, the play is ambiguous. The ambient temperature refers to the temperature of the rest of the board besides the local region. In general it is the value of tenuki. As a rule it is time to make a local play when the ambient temperature drops below the local temperature. Sometimes the choice of a local play depends on the ambient temperature. A gote play, which lowers the local temperature, may be played with sente if its gote response is hotter than the ambient temperature. When both a local play by either player and its gote response are hotter than the ambient temperature, the play is double sente. If two gote plays have the same size (in other words, if they are miai), then their combined temperature is lower than the local temperature of either one. If a play is the last one before a significant drop in the temperature of the whole board, it is tedomari. Tedomari is worth fighting for, as a rule. Comment on game temperature moved. See also Temperature and Terminology Discussion. [1] This is not the same sense of urgent as in Play Urgent Moves Before Big Moves. Both kinds of moves are urgent in this sense. -- Bill Spight Path: CGTPath · Prev: Minimax · Next: Environment This is a copy of the living page "Temperature" at Sensei's Library. ![]() |
