One common dilemma that players routinely face is that of hitting a tasty blot or making a strong blocking point. In very general terms, hitting the blot is most likely right. Hitting both gains ground in the race and prevents your opponent from improving his structure, which in normal positions will outweigh other choices.
As your opponent’s position becomes stacked and stripped, however, hitting blots recedes in importance while building blocking points grows. The reason has to do with timing. A stacked position can be repaired, but typically some time is required. A game with hitting and recirculating of checkers provides exactly that sort of time. A prime, however, tends to shorten the game, as a single bad roll can destroy the weaker player’s position in an instant. By building a prime, the aggressor can accelerate the crisis point to his advantage.
