Greetings...

Since last issue Joonas, Fizmo and Bvowk have worked together to provide a
new hill server, currently offering three play-by-email hills - beginner,
tiny and limited process.  Check out the new hills at:

  http://sal.math.ualberta.ca/

Three rounds of the Redcoders Frenzy have taken place.  Roy van Rijn took
first place in the Holding Hands and Limited Distance rounds while first
went to Zul Nadzri in the Laughing Loser round.  In the current standings,
Roy van Rijn holds first place with a 35 point lead, followed by Christian
Schmidt and Zul Nadzri in second and third.

Christian Schmidt illustrates another of his papers this issue, sharing the
inner workings of Soldier of Silkland.

342 successful challenges have passed since issue 87, with 15 warriors
leaving the hill with a 3 digit age.  Toxic Spirit attained the respectable
age of 685 before dropping off.  Return of Vanquisher (age 640) and
Thunderstrike (484) perished together in a ;kill accident.  Also pushed
from the hill were unheard-of (355), Numb (312), Now you're in trouble (290),
Candy II (282), Digitalis 2003 (222), Claw 2 (190), Fuse (152), devilish 2.02
test (148), Preserver (144), Mordred's Son (138), Soldier of Silkland (114)
and Tuesday's Torment (103).

Koth report:  Once again Recon 2 is seen most frequently topping the hill,
after 77 challenges.  Toxic Spirit follows closely, taking first place 66
times.  Also performing well were King of Metal (42 times king), Damage Inc
(act II) and Thunderstrike (29 times each), Reepicheep (19), Preserver and
Return of Vanquisher (14 each).

Son of Vain increased it's oldest Koth record, taking first place age 1780.
Then, on 6th October, SoV became the third warrior in Corewar history to
reach the age of 2000.  Congratulations to Ian and Joonas.  The two warriors
which previously made 2000 were Sphinx v2.8 by W. Mintardjo on the Intel
'88 hill - followed by Robert Macrae's Thermite II on Pizza's '94 hill.

88 challenges pass since last issue with Sunset taking the number one spot

Koth since it's arrival - 39 challenges ago.  King of Metal claim's to be

Hand-shake alert: two warriors, Sunset in September and Sunrise are both

Extra Extra - Soldier of Silkland by Christian Schmidt

Last issue I discussed unheard-of which uses a 6-line silk-dwarf combined
with silk/imps.  It reached an age of 355 on the 94nop hill which was quite
good for such a defensive warrior.

However, I was also engaged in writing a nice 8-line silk-dwarf which could
easily be combined with another 8-line paper.  I tested several 6-line
stones, both new and published, prefixing them with a 2-line silk copier.
The best results were achieved when I used the stone from John Metcalf's
Uninvited.

After some optimization of the silk-step, I found a step not only with nice
scores against scanners, but also against several one-shots.  However, the
down-side is, it loses against papers and stone/imps much more than
unheard-of's silk-dwarf.  So, the decision to add a second paper was easy
to justify.

This time I wanted to create a more offensive warrior and I finally selected
the paper from Reepicheep, which gave much better scores than with all of my
own papers.

After finding the best boot positions I added David Houston's extended Q^4
scanner, which gave some extra points compared to the normal Q^4 scanner.

Okay, without further ado, here is the code:
