      AB: The hormone testosterone (T) has a central role in recent 
          theories about allocation of status ranks during face-to-face 
          competition. It has been methodologically convenient to test the 
          hypothesized T mechanism in physically taxing athletic contests, 
          where results have been supportive, although their 
          generalizability to normal social competition is questionable. 
          Competition among chess players is a step closer to normal social 
          competition because it does not require physical struggle, and it 
          is the arena for tests of the T mechanism which are reported 
          here. We find that winners of chess tournaments show higher T 
          levels than do losers. Also, in certain circumstances, 
          competitors show rises in T before their games, as if in 
          preparation for the contests. These results generally support 
          recent theories about the role of T in the allocation of status 
          ranks.
