How many points is each chess piece worth? I am a beginner at chess; please answer this question for me.

How many points is each chess piece worth?
The answer by MikroDel gives the commonly-used &quot;Reinfeld values&quot; of pawn=1, bishop=knight=3, rook=5, and queen=9 (kings are essentially worth an infinite number of points, because the game ends if it is lost). While this is a good guide, chess is rarely that simple. Many books will give the value of bishops as 3.5 instead of 3, simply because they are often much stronger than knights in endgames and open middle-games.
There are other things to take into account as well. For example, bishops are much stronger if you own both of yours, but you opponent has already lost/traded one or both of theirs. The nature of the position can also affect the worth of individual pieces, as a position that is completely blocked up might leave a bishop with no useful squares to go to while a knight may be able to jump straight over the obstruction.
Another example of how the Reinfeld values can be misleading is that 3 minor pieces (bishops and knights) are often more powerful than a single queen, provided that they are used properly.
For some further reading, you might also want to take a look at http://en.wikipedia.org/wiki/Chess_piece_relative_value which has a much more detailed explanation.
