Balance of power
As a part of positional judgment players assess the balance of power. The question analysed here is: who has the stronger positions on the board at this stage? Although it is not easy to quantify, the relative strength or weakness of a player's positions is known as the concept of thickness.
If both players are not significantly behind in the balance of territory, the one who is ahead in the balance of power has the better chances to win. There are various techniques to convert a power advantage into a territory advantage. Examples are using the position of strength to set up an attack, or using it as a support position to invade a territorial framework.
