And boy, were they. As is the custom in the ACPT, Puzzle #5 separated the wheat from the chaff. The puzzle was courtesy of David J. Kahn, who caused the wrath of over 500 of the 700+ solvers who still held papers at the end of the time limit.
Puzzles Four (Paula Gamache) and Six rolled as expected with little drama or surprise, but much love to the constructors. And when Maura Jacobson's name was announced as the Puzzle Six constructor, the solvers produced an ovation as loud and as long as any the ACPT has ever experienced.
We are still also waiting for official standings to be posted. As soon as we know, you will know. Remaining constructors are Oliver Hill (the youngest ACPT constructor ever) and Bob Klahn, with the latter the heavy favorite to provide the themeless crusher that will decide the champions.
