My apologies for the delay in posting. Here is our winner, Colie Hoffman!
Colie's winning word was "schism." Colie and Joe Nofziger used up all the really difficult words (e.g. zugzwang, bouquiniste, lagniappe, estaminet, vichyssoise), so we had to revert to the merely difficult (e.g. muumuu, exchequer, mulct, troglodytic, asceticism). Several of the contestants went many rounds this time. Yippee!
