We should reconsider the value of the Queen.................

[pichy]

Is the value of the Queen too high if it is set to 9? Here are two interesting position that can give us an ideal of how to set the correct value of the Queen.


PS: We should reconsider the value of the Queen to no more than 8.5 at the most

In the first position a Bishop and a Rook value at 8 points give us a draw [:wink/size]
[D]8/8/8/3kb3/3r4/3KQ3/8/8 w - - 0 1

But if we add an extra pawn making it 9 points to both sides according to the old values of the pieces then Black win easy

[D]8/8/8/2bkp3/3r4/3KQ3/8/8 w - - 2 1

[hgm]

In the first position a Bishop and a Rook value at 8 points give us a draw

Well, that is consistent with a Queen value of 10, right? R+B ~ 8, and +2 is within the draw margin for Pawnless end-games (where the score has to be divided by 2, approximately). Even +3 in a Pawnless end-game (i.e.minor ahead, e.g. KRNKR )is usually not enough.

The second position of course says nothing about the Queen value, as there is no Queen (on the next move).

You made a good point Muller, if it is White to move in this position where the King is not in check the best that White can do is get a draw:

You made a good point Muller, if it is White to move in this position where the King is not in check the best that White can do is get a draw:

Well, that is still consistent with Q=10: R+B+P = 9, so you have +1, which is still well below the draw margin, as white is still Pawnless.

I like the evaluation of the pieces according to Emanuel Lasker 1947 where on average the queen value should be 8.5


In chess, the chess piece relative value system conventionally assigns a point value to each piece when assessing its relative strength in potential exchanges. The exact piece values will depend on the game situation, and can differ considerably from those given here. In some positions, a well-placed piece might be much more valuable than a badly-placed piece may be completely trapped and, thus, almost worthless.
Standard valuations
The standard valuations for the pieces are as follows,these are the values used today:
Queen-9
Rook-5
Knight and Bishop-3
Pawn-1
King-1000000000000000000000000000000000000000000000000000000000

In the endgame, when there is little danger of checkmate, the fighting value of the king is about four points (Lasker)
The king is good at attacking and defending nearby pieces and pawns. It is better at defending such pieces than the knight is, and it is better at attacking them than the bishop is (Ward).
This system has some shortcomings. For instance, three minor pieces (nine points) are often slightly stronger than two rooks (ten points) or a queen (nine points) (Capablanca, de Firmian,Fine , Benko ).
Alternate valuations
Although the 1/3/3/5/9 system of point totals is generally accepted, many other systems of valuing pieces have been presented. They have mostly been received poorly, although the point system itself falls under similar criticism, as all systems are very rigid and generally fail to take positional factors into account.

According to Burgess, Lasker (in his book Lasker's Chess Manual) gave these relative values for the early part of the game (Burgess 2000:491): World Champion Emanuel Lasker (Lasker 1947) gave the following values (here scaled and rounded so pawn = 1 point):

World Champion Emanuel Lasker 1947 gave the following values (here scaled and rounded so pawn = 1 point):
• pawn = 1 (on average)
• knight = 3½
• bishop = 3½ (on average)
• rook = 5 (on average)
• queen = 8½.
However Lasker adjusts some of these depending on the starting positions, with pawns nearer the centre, and bishops/rooks on the kingside, being worth more:
• centre (d/e-file) pawn = 1½ points, a/h-file pawn = ½ point
• c-file bishop = 3½ points, f-file bishop = 3¾ points
• a-file rook = 4½ points, h-file rook = 5¼ points.


Howard Staunton in The Chess-Player's Handbook notes that piece values are dependent on the position and the phase of the game (the queen typically less valuable toward the endgame), but gives these values, without explaining how they were obtained (Staunton 1870, 30–31):
• pawn 1.00
• knight 3.05
• bishop 3.50
• rook 5.48
• queen 9.94
In the 1817 edition of Philidor's Studies of Chess, the editor (Peter Pratt) gave the same values.
The 1843 German book Handbuch des Schachspiels by Paul Rudolf von Bilguer gave
• pawn 1.5
• knight 5.3
• bishop 5.3
• rook 8.6
• queen 15.5
When normalizing so that a pawn equals one:
• pawn 1
• knight 3.5
• bishop 3.5
• rook 5.7
• queen 10.3
Yevgeny Gik gave these figures based only on average mobility:
• pawn 1
• knight 2.4
• bishop 4
• rook 6.4
• queen 10.4
• king 3 (as an attacking and defensive piece)
but Andrew Soltis points out problems with that chart and other mathematical methods of evaluation (Soltis 2004:10-12).

Grandmaster Larry Evans gives the values:
• pawn = 1
• knight = 3½
• bishop = 3¾
• rook = 5
• queen = 10 (Evans 1967).
A bishop is usually slightly more powerful than a knight, but not always – it depends on the position (Evans 1967). A chess-playing program was given the value of 3 for the knight and 3.4 for the bishop, but that difference was acknowledged to not be real (Mayer 1997).
Another system is used by Max Euwe and Hans Kramer in Volume 1 of their The Middlegame, with values
• pawn = 1
• knight = 3½
• bishop = 3½
• rook = 5½
• queen = 10.
Bobby Fischer gave the values:
• pawn = 1
• knight = 3
• bishop = 3¼
• rook = 5
• queen = 9
An early Soviet chess program used
• pawn = 1
• knight = 3½
• bishop = 3½
• rook = 5
• queen = 9½
Another popular system is
• pawn = 1
• knight = 3
• bishop = 3
• rook = 4½
• queen = 9 (Soltis 2004).
Changing valuations in the endgame
The relative value of pieces changes as a game progresses to the endgame. The relative value of pawns and rooks may increase, and the value of bishops may increase also, though usually to a lesser extent. The knight tends to lose some power, and the strength of the queen may be slightly lessened, as well. Some examples follow.
• A queen versus two rooks
• In the middlegame they are equal
• In the endgame, the two rooks are somewhat more powerful. With no other pieces on the board, two rooks are equal to a queen and a pawn
• A rook versus two minor pieces
• In the opening and middlegame, a rook and two pawns are weaker than two bishops; equal to or slightly weaker than a bishop and knight; and equal to two knights
• In the endgame, a rook and one pawn are equal to two knights; and equal or slightly weaker than a bishop and knight. A rook and two pawns are equal to two bishops
• Bishops are often more powerful than rooks in the opening. Rooks are usually more powerful than bishops in the middlegame, and rooks dominate the minor pieces in the endgame

I have got this information from wikipedia but i have put it in my own words

[Graham Banks]

Is the value of the Queen too high if it is set to 9? Here are two interesting position that can give us an ideal of how to set the correct value of the Queen.

PS: We should reconsider the value of the Queen to no more than 8.5 at the most

I disagree with you completely.
I believe that the value of the queen is under-rated, especially if you take the old pawn=1, knight/bishop=3, rook=5, queen=9 values as a base.

Any Chess engine could easily be modified to adjust the value of the Queen depending on the stage of the game like Lasker recommended before the era of computer, for instance if the game has not reached the endgame which is normally after move 40 then this logic could be applied.


if(Condition)
Statement1;
else
Statement2;


if(Number of moves < than 40)
Statement1;value of Q=10.5
else
Statement2; value of set Q=8.5

showing a particular position where the queen is useless says nothing about its optimal value in a computer chess program.
just take an open source program like Fruit for instance, and try to modify the queen value, you will see !
otherwise use CLOP to calculate optimal piece values. You'll be very surprised (and not just by the queen)

This is where a top GM excel over top engines, that in certain positions where the position is closed or blocked the engine only think about the value of its pieces, for instance in this internet game GM Nakamura knew that the two Rooks where not superior to his two Knights and made the down exchange. Rybka only knew that the two Rooks each worth 5 points and an extra bishop was winning but GM Nakamura knew how to evaluate the position better, in reality the two rooks and extra bishop were useless in such position and with time pressure Rybka not knowing what to do or how to break the position finally lost the game:

So here White just plays e4
What is the value of the two queens?
