The Most Important Positional Principles

1. Pair of bishops is a serious advantage (especially in endgame). If you have pair of bishops – try to open the position. And in opposite if your opponent has it  try to close the position.

2. If you have advantage in space – avoid exchanges, which can lead to exemption of the play. When you have advantage in space your opponent’s pieces choke of the lack of space and fetter in maneuvers. That is the reason why you should avoid exchanges in such situation.

3. While you possess the initiative it is better to avoid simplifications. Every exchange should be motivated; it means it should bring some positional or tactical dividends.
