The side which wins the rook is said to have won the exchange, while the other player has lost the exchange, since the rook is usually more valuable. Alternatively, the side that has won the rook is up the exchange, and the other player is down the exchange.
Is a rook worth a Knight and bishop?
A Rook in play is worth nearly a Knight and two pawns. A Rook and pawn are nearly equal to two Knights, but are not so good as a Bishop and Knight. The Bishop is the more useful for stopping passed pawns; the Knight for attacking pawns on either color, especially doubled pawns.
When does a bishop become active in chess?
A bishop is called active if he is in front of his pawns and inactive if it’s trapped between his own pawns. From these simple definitions, anyone can understand the difference between them. People tend to confuse these definitions because in many cases both of them are valid.
What makes a good bishop a bad bishop?
It is obvious here that there is a distinction between a good and a bad bishop. If a Bishop is on the same color square as his own pawns, then it is considered as a bad Bishop. Another identification of a bad Bishop, obviously very similar to the previous one, could be the Bishop who can attack his own pawns only.
How do you keep a pair of bishops together?
Basic Idea: Keep the bishops together. They form a large net (restricted area) from which the opponent king cannot escape. Keeping the bishops together and using the king for support, make the restricted area smaller to push the opponent’s king back to an edge rank or file.
How are auxiliary bishops chosen in the Catholic Church?
Auxiliary bishops are usually given to dioceses that have a large population or other needs that warrant one or more auxiliary. Some American archdioceses have several, such as Los Angeles, which has seven active auxiliaries. The diocesan bishop will ordinarily prepare the terna of candidates, which he turns over to the nuncio.
