The objective of this paper is to present anew dimension of Game Theoretic Se-mantics (GTS) using the idea of the coor-dination problem game to explain thesemantics of metaphor. A metaphoricalexpression1 such as 'man is a wolf' is acontradictory statement that insists allobjects in the set of 'man' also falls under'wolf'. The study of metaphorical expres-sion should be on intentions of such con-tradictory language use, their intendedeffect, and the conditions to lead to the ef-fects. This is the tradition of Rhetoricsince Aristotle. It may be natural to char-acterize this approach as pragmatic in thetradition of the late 20th century paradigmof linguistics, which is the trichotomy ofsyntax, semantics and pragmatics. How-ever the pragmatic approach cannot ex-plain what Richards (1936) called'tension' between two thoughts in a meta-phorical expression. GTS has been devel-oped as a possible substitute to the Tar-skian truth conditional semantics. Thispaper explores a new possibility of GTSin the coordination problem game intro-duced by Lewis (1961) for a semantics,which admits the plurality of meanings.
