The
Colorado Chess Informant
(CCI) is the official publication
of the CSCA, published four times a year in January, April,
July and October.
Articles in the CCI
do not
necessarily reflect the views of the
CSCA Board of Directors or its membership.
It is something, how far that computer chess programs have
come in such a relative short amount of time. Today they are so
powerful that even that app loaded on your cell phone could rou-
tinely defeat Granmasters, even the current World Chess Cham-
pion if he would decide to take on the silicone monster, which I
doubt that he ever would. It could be extremely embarrasing to
have his Norwegian backside thoroughly kicked from here to
next Tuesday.
Today, players use chess programs to work out ideas and ana-
lyze, even Grandmasters regularly use them to test out ideas be-
fore tournaments or matches. Perhaps that is how it should be.
Gone are the days of “Man vs Machine”, it is just no contest
anymore.
May Caissa be with you.

Electronic voting/by-laws proposed changes.
I
joined the CSCA board because I felt the organization was becoming irrelevant after witnessing events the last couple years. In
particular if you couldn't get to the Colorado Open you had no or difficult representation and the results didn't seem to always
represent the membership as a whole-not surprising when so few attended the meeting. But, rather than complain I decided to help
out.
First, thanks to all the volunteers and sounding boards who pitched in and gave advice and did the legwork to investigate by-laws
and electronic voting in other states and the USCF take on it and looked at several (not free) electronic voting systems available.
Paul will be soon be calling a membership meeting to vote on a ballot measure, per current by-laws requirements, to place the pro-
posed changes before the membership. It will include the exact wording and plans. Here's the basics.
Electronic voting:
Implement voting by email on some votes (an “e-vote”). A ballot may be an e-vote if...
1. The President declares it so (always assume no other by-law restrictions such as certain Board and fiduciary responsibilities).
2. The Board votes by majority to make it so.
3. By membership petition.
The process:
There will be a minimum time for the e-vote to be in front of the membership for open discussion, likely (we're still hammering out
the details) 3 weeks. This allows for discussion by individuals, on blah-blah-blah's, sorry, blogs, etc.
The author of the e-vote will be able to post on the CSCA site an official “pro” discussion. We'll also post a “con” side but need to
figure out who would “own” that (likely a Board selected volunteer).
An e-mail will be sent to all members who wish to be included, meaning they've provided an email address, with the ballot measure
wording, website for information, and intrinsic security information. Security is a major consideration. There are several methods to
insure the email comes back from the address it was sent to and not forwarded to a third party or intercepted.
“Replying” with For or Against completes the member side.
Ballots will be tallied by the Secretary or Board.
Communication:
The President will announce the results either on the official “Presidents Plate” or during a membership meeting.
Separately, we'll also be proposing the Board be elected by e-vote, and “cleaning up” legal issues around minors acting as agents for
the CSCA.
My personal take on this is it's a way to improve input with low risk while maintaining membership ability to make changes via the
petition route.

Brief Analysis of the
ARB System (A00)
© Copyright 2015 by Colin James III. All rights reserved.
The ARB system is named as such by its author Anthony R.
Brown who invented it to play against computer engines. A
merit of the system, as the Hippopotamus opening (B00), is that
the pawn structure dictates both the defense and the offense,
supporting Philidor that pawns are the soul of chess.
Brown assigns piece values as: Q 9.0; R 4.5; B 3.5; N 3.5; and P
1.5. The rook has a value lower than 5.0 for the purpose of being
a pawn nanny on the flank or for sacking.
The pattern of pieces is the same for Black or for White in
reverse. For Black, Brown's moves not in strict order are:
1...e6
2...d6 3...h6 4...a6...g6 6...b6 7...Bb7...Bg7,
followed later by
knight moves such as
Ne2
and
Nd2,
as in Diagram 1. For White,
Brown's moves are the same but on opposite colored squares as:
1.e3 2.d3 3.h3 4.a3 5.g3 6.b3 7.Bb2 8.Bg2,
with a move in hand
over the black pattern.
1.e3 e5 2.d3 d5 3.h3 Nf6 4.a3 c5 5.g3 Nc6 6.Ne2 (transpose
6.Bg2 Be6 7.Ne2) 6...Be6 in Diagram 2.
Diagram 2
7.Bg2 Bd6 8.g4 0–0 9.Nbc3 h6 10.Ng3 Qd7 11.0–0 Rad8 12.b3
a6 13.Bb2 Rfe8 14.Rc1 Bc7 15.Nb1 d4 16.Nd2 b6 17.Re1 Nd5
18.Nde4 Rf8 19.a4 g6 20.exd4 exd4 21.a5 Nxa5 22.Qd2 Kg7
23.Ra1 Bf4 24.Qd1 Qc7 25.Ne2 Nc6 26.Rxa6 Bc8 27.Ra1 f5
28.gxf5 Bxf5 29.c3 Bxe4 30.dxe4 dxc3 (transpose 30...Nxc3
31.Nxc3 dxc3) 31.Nxc3 Nxc3 32.Bxc3+ Nd4 33.Ra2 Be5
34.Qa1 Rf7 35.Re3 Kh7 36.Qf1 b5! (commence the win) 37.Bb2
Qe7 38.Rd3 Qh4 39.Bxd4 Bxd4 40.Rdd2 Qg5 (prepare the king
side whammy, with a rook and opposite color bishop, in
Diagram 3, and ending with (-#29) 83.Ra2) 0-1
Diagram 1
Brown often keeps the king uncastled to move around behind
the mass of pieces in the center of the board. In Brown's
expositions, the move choice by the computer is not always the
strongest from the engine. Hence the same chess engine does not
necessarily reproduce the same computer moves as published by
Brown. The time control is usually 60 seconds per move. Brown
typically plays a chess engine only once to demonstrate his win.
No anthology of multiple games per engine is published as yet.
The last message traffic for ARB is from 09/2013 of non-
academic internet writings.
ARB is not an effective strategy to obtain computer draws.
