The Bishop Pair by Efstratios Grivas

The possession of the bishop pair (vs. bishop & knight, or knight pair) is an important strategic element that may guarantee superiority and even determine the outcome of the game. In modern chess, the bishop pair has been established as a positional advantage in the majority of cases, and it’s very common nowadays to hear teachers tell their students ‘keep your bishops’ or ‘capture that bishop’.
In today’s chess, the importance given to this element has increased to the point that in some of the most popular opening variations, the main goal has become to gain the bishop pair. That is because the bishop pair can be a powerful advantage in any phase of the game. For example, it’s a lethal weapon in an attack against the king. It can also be very efficient in attacking weaknesses: one bishop can put pressure on the target, while the other attacks the defending piece. However, it is the endgame where it is particularly strong.
