What rules should we follow in Chess to win games.
Here are basic rules which I already know.
1. 3 Pawns= 1 Knight = 1 Bishop
2. 5 Pawn = 1 Rook
3. 9 Pawns = 1 Queen
4. King should be saved from attacks.
5. Pawn should be Promoted fast to Queen in end game
6. Knight & Bishops should be promoted ahead to attack opponent.
What else is needed to win Games in Chess. Once I learn new rules I
will add them to GetClub Chess.
Play Chess at: http://www.GetClub.com/Chess.html and tell my which
rules it do not follow.
Now it is fast and plays quite good moves.
Bye

I think it's more like 3.25 pawns for a bishop, and an extra half-pawn if a
side is up a bishop. With opposite bishops, the side with the initiative in
the middlegame is effectively a piece up.
> 2. 5 Pawn = 1 Rook
More like 4.5 or 4.75.
> 3. 9 Pawns = 1 Queen
About right.
> 4. King should be saved from attacks.
Thanks!!
> 5. Pawn should be Promoted fast to Queen in end game
Whenever possible.
> 6. Knight & Bishops should be promoted ahead to attack opponent.
Posted up in enemy territory is more like it.

These numbers were originally used in order to speed
up the search, because integer math was faster than
calculations using decimals.
Note that in general, a Bishop is better than a
Knight, a Queen better than R + N + P (= 9 points).

Actually, this rule should go in the number one position
because it takes precedence over everything else. [See:
the won game section of the rules of chess.]
> 5. Pawn should be Promoted fast to Queen in end game
Many chess programs have had a serious flaw in
that they could not "see" the pawn promoting, so they
failed to take advantage of a passed pawn, or to stop
one of the opponents. In fact, I noted this same flaw
in one featured game by Rybka -- currently rated
around 3000!
Nevertheless, the advancement of a passed pawn
is a matter of judgment; too fast or too soon, and
the pawn may be lost. Too slow or too late, and it
may be a waste of time.
> 6. Knight & Bishops should be promoted ahead to attack opponent.
Hold on there! In the opening phase, the minor pieces
need to be "developed", but it is unwise to launch any
premature attacks.

Search extensions for checks and captures during
tactical exchanges would be a powerful addition. A
very simple example of this is:
1.e4 e5
2.Nf3 Nc6
Now White should "see" that 3.Nxe5 does not win
a pawn because of the recapture ...Nxe5, after
which there are no more immediate checks or
captures (i.e. a "quiet" position). The search
ought to spot this fact *before* doing the next ply,
the one where all moves are examined and scored
and compared.

Somewhat unlikely. Fixed-point calculation is
fairly easily done ... and if you don't want to go down
that road, you can adjust the scale from full pawn (1)
to deci- (10) or centipawns (100) instead.
Evaluating material in terms of pawns predates
computers. The first examples of it I remember off hand date
from around 1850, but I'm certain it's older than that.

It is? The queen is more mobile than the group, but if that's all that is
on the board, most people can't even win Q v. N let alone with the R+P.

Here white is a pawn up. and it proceeds with killing of Blacks Queen
in exchange for Knight and Bishop. White was able to trap the queen by
pinning it against the King.
