The position does not have to be exactly the same, just very similar. Where this is done deliberately by the later composer, the term plagiarised is used.

However, anticipations are not always noticed immediately.

BAD BISHOP  look up translate image
Any ineffective Bishop. When a Bishop has little or no mobility because of being hemmed by Pawns positioned on squares of the same color as the Bishop's square, it is said to be a "bad Bishop".

BISHOP PAIR  look up translate image
Two Bishops vs. a Bishop and a Knight or two Knights. If both Bishops on the same side have survived late into a game of Chess, then their value is enhanced for two reasons. Together they can attack a piece on any color square. Their mobility is usually less restricted by Pawns late in the game. Therefore, a Bishop pair is a notable advantage. Two bishops against a bishop and knight or two knights. Two bishops are effective together because they control diagonals of both colours, and work very well in open positions. See "Opposite colour bishops".
