Subject: How much advantage we get for White pieces?
When I play White GetClub Chess shows a loss of 1 point and when I
play black GetClub shows itself an advantage of 1 point.

Is having white pieces equal to having an advantage of Pawn?

In most of the games I find GetClub gives 1 pawn advantage when having
white and similarly 1 pawn loss when it is having black pieces.

I have not taught it any thing like that but when it calculate the
position it gives +1.0 point to white?

What do expert players think about it. Does getting white pieces worth
getting an extra pawn?

When playing against Rybka, GetClub always shows +1.0 point for the
player who takes white.

No.

I believe the advantage equates to about 40
rating points, but in any case, it is worth
significantly less than a pawn.

Perhaps the programmers are showing the
position-score from White's perspective,
regardless of who has what color or of who
is on move.

Weak players may confuse you by posting
outmoded or simply poor information, but as
for experts, they seem to perform (nevermind
what they may /say/) roughly 40 rating points
better with White than with Black, on average.

Having this tidbit handy, we can safely ignore
what is said, argued, claimed, propounded or
even bloviated, in favor of real-world results
over hundreds of thousands of games,
averaged.

However, it is quite possible that at the low
level of play at GetClub, the advantage of
having the move is larger than in the world of
competitive chess.

No, it looked perfecly fine here. It's probably your Newsreader's fault.

It was only ISO-8859-1.

Your browser must be showing those numbers differently. Let's try
them this way:

of the c- or f-pawn =3D 1 and 1/2
of the b- or g-pawn =3D 1 and 1/4
of the Knight =3D 4 and 1/2
of the QB =3D 4 and 1/2

Yes this numbers make sense.

My browser is fine,
but I use text based usenet,
subscribed to rec.games.chess.computer.

I avoid web forums anytime I can :-)

Usenet gateway probably twisted it.

Emanuel Lasker, world champion 1894-1921, gave the following table of
relative values in "Lasker's Manual of Chess" (1925):

The Value

of the first move =3D 1
of the second move =3D 4/5
of the third move =3D 3/4
of the fourth move =3D 2/3
of the fifth move =3D 1/2
of the d- or e-pawn =3D 2
of the c- or f-pawn =3D 1=BD
of the b- or g-pawn =3D 1=BC
of the a- or h-pawn =3D 1/2
of the Knight =3D 4=BD
of the KB =3D 5
of the QB =3D 4=BD
of the KR =3D 7
of the QR =3D 6
of the Queen =3D 11

He further wrote: "These are, of course only estimates based on
experience. The numbers given are obviously only approximate. But even
though the position is complicated, they can still be of service in
helping to determine whether one may venture upon sacrificing a piece
for two pawns, and in elucidating similar thorny problems."

looks like missing decimal point or do.

The rule of thumb is that three tempi is about a Pawn. Being on the
move, in general, is worth about 1/3 Pawn.
