In Response To: No fireworks, but I still blundered (Timothy Chow)

Magriel's criteria suggest a safe play, so I decided to move my blot on the 15pt. However, there are still plenty of indirect fly shots, not to mention our straggler in the opponent's home board. My interpretation of these results is that making the 8pt reduces our blot count, which limits the damage if White starts to attack. Not that the 8pt doesn't have some value, but I do think Magriel's heuristic that points 6 pips apart can't be part of the same prime is still valid.
