Implement the outpost evaluation #178

Closed programarivm closed 2 years ago

programarivm commented 2 years ago

An outpost can be thought of as a strategic square where a minor piece — a bishop or a knight — is placed in such a favorable way that the opponent definitely wants to trade it for one of their minor pieces, or is even willing to trade it for a major piece. This usually happens when such square is protected by a pawn and cannot be attacked by an opponent's pawn as described in the example below.

Keep it up, and happy learning!
