Over night I performed some Monte-Carlo runs (with the heuristic by Stefan Schwarz). Starting position (from the challenge game) x1 x6 x3 -- -- x5 x2 -- -- -- x4 -- -- -- y2 -- -- -- y3 y1 -- -- y4 y6 y5 X to start; score after 50,000 games: 24,952 - 25,048 Starting position (my setup with 180 degree symmetry) x1 x6 x3 -- -- x5 x2 -- -- -- x4 -- -- -- y4 -- -- -- y2 y5 -- -- y3 y6 y1 X to start; score after 50,000 games: 25,077 - 24,923 Starting position (my setup with mirror symmetry) x1 x6 x3 -- -- x5 x2 -- -- -- x4 -- -- -- y3 -- -- -- y2 y6 -- -- y4 y5 y1 X to start; score after 50,000 games: 25,165 - 24,835 So, within standard deviation, all the results are the same. Ingo. PS: In another series I will test Theo's setup versus it's symmetries.
