Core Warrior is a weekly newsletter promoting the game of corewar.  Emphasis
is placed on the most active hills--currently the '94 draft hill and the
beginner hill.  Coverage will follow where ever the action is.  If you have
no clue what I'm talking about then check out these five-star internet locals
for more information:

FAQs are available by anonymous FTP from rtfm.mit.edu as
pub/usenet/news.answers/games/corewar-faq.Z
FTP site is: ftp.csua.berkeley.edu /pub/corewar

Greetings.

There has been a lot of discussion recently in r.g.c about new opcodes and
new standards. Here is what Scott Manley wrote:

I also think such a group is needed. However, who is going to create it? I
am willing to collect a list of names of those who are interested in being
a part of the core of this group. It would also be good if you could give
me some details in what areas you would like to contribute, eg. writing code,
writing documentation, writing newsletters/articles, developing standards,
promoting the game, vote taking, management of tasks, etc. And if you can 
write code, which languages can you code in? The more details there are, the 
easier it will be to allocate tasks.

One of the problems with creating groups like this is that nothing will ever
get done unless someone takes the initiative. A list of volunteers is a good
start. I will post this list (assuming I get any volunteers) in a week or so
or include it in the next CW.

have the patience to fill in the details this week.

Q^2 scans are still dominating the most of the top positions on the hill.

Edgar is back from vacation! Atom Smasher 2 made a brief appearance but was
killed for some reason :-) Just out of interest, it was just an imp/stone 
with a Q^2 scan. These Q^2 scans seem effective enough to upset pspace logic
sometimes.

It'll be a long ride to the top because of the 'test' option. Maybe a new HOF

The Hint
Quick Scanners
by Anton Marsden

This hint is for the more "developed" players. If you would like to find out
more about the best qscanners around, check out some of the older issues of
CW (37 and 40 in particular).

QScans are great if you want to use them as a front-end for a paper/bomber
but they are not as effective when coupled with scanners, the reason being
that the scanner will detect the qscan code and attempt to neutralise it.
It's not so bad if your scanner just drops one or two bombs on the scanned
position but usually you want to drop a carpet of bombs. There are several
ways this could be dealt with: either modify the scanner or modify the
qscanner. Modifying the qscanner is probably the best option.

If you have a mod-4/8 scanner with small distance between scanned locations, 
eg. SEQ pos,pos+12 you can align the qscan such that it is invisible to your 
scanner:

SEQ 100,200
JMP fnd
SEQ 300,400
JMP *-2     ; scanned
SEQ 500,600
JMP fnd
SEQ 700,800
JMP *-2     ; scanned
...

For a mod-5/10 scanner, try using a combination of SNE/SEQ and SEQ in your
qscan. In some cases it won't be necessary to hide the qscan from the scanner
completely, but the more that's hidden the better.

implement than the above code suggests... but good luck :-)
