Planning the game

I (Holigor) want to start this discussion with a need for classification. The reason for this comes from my draughts experience. I can outline several possible types of positions:

• Balanced positions - both opponents have about the same sure territory and approximately equal spheres of influence.
• Corners against frameworks.
• Thick but slow against thin but fast.
• Positions where one of the opponents has a weak group.
• Positions where both opponents have weak groups.
• Positions with multiple weak groups. Vulnerable to splitting attack or leaning attack.
• Add another type here.

Of course, tactics play a major role and you have to see those important points and weaknesses in the positions of your opponent. But, I believe there are several general ideas for each type of position. It would be helpful to develop the list of those ideas.
