You seem to have "handpicked" them for DarkThought because it solves 20 of them in less than 5 minutes on a 500MHz AlphaPC-164 (most of them in less than 1 min) and it keeps the answers for at least another 5 minutes. What I do not like about this test, however, is the fact that a couple of positions are taken from other well-known suites like BK or LCT-II. This breaks independence between test suites and reaps multiple rewards for solving the positions. =Ernst=
