III.  The Scoop:

The great mixing bowl we call 'King of the Hill' was whipped furiously this
week, and one long-time competitor was slopped out (hey, you try coming
up with the metaphors!):

 21  38/ 51/ 11               Charon v8.1   Cisek,Strack,Kline     124     629

Charon has had a long and successful run, was killed by imps, then
reprogrammed back to the top, but has been on the skids the last couple
of weeks.  It is a prime example of teamwork, as Stefan and I took a turn
at beefing up JC's original concept.  We would add a fourth author,
but there aren't any more consonants in CiSeK!  :-)  What's next for Charon?
Maybe a decoy (ignore those groans from SS).  Maybe a gate?  Or maybe just
a new constant.  Maybe someone could figure out how to eliminate the 
jmp instruction I added to get the extended scan time.  I waited a few days
and resubmitted Charon, but it only lasted seven challenges, so the current
version is dead dead dead.

Charon's demise is due in part to the hard work on the part of many
to create a successful stone fighter.  Stones are always hard on scanners
and there have been quite a few tried on the Hill recently.  Then along
comes Dan Nabutovsky to show how it's done.  His 'Moonstone' program (source
just published - everyone send him a thank-you) is riding high on the Hill, and 
looks like it has staying power.  Moonstone is not as small as earlier
bombers, and also differs in its amazingly small bomb-step size, and 
simplified gate.  It has a very interesting, compact, phase-switching mechanism
which is worth studying.  (Uh-Oh, latest standings show Moonstone dropping,
anyone going to 'fess up and tell us why?)

'+0 Stormbringer', current endurance champ, took a near-fall
along with former high-riding 'Sphinx v2.8' and sometime leader 'Night',
but, once again the imps out-tough the challengers.  (Too late to
name it Methuselah now, DN)

 20  28/ 34/ 38              Pippin V 1.1      Arno Fuhlendorf     123      23

Speaking of rankings, here's an interesting Top Ten, proving that both
old and new programs are enjoying their successes (longevity on the right):

  1  47/ 44/  9               Medusa's v7   Mintardjo & Strack     150      82
  2  47/ 45/  8                 prototype        Stefan Strack     149       1

Best pun of the week (non-native English-speakers please bear with):
   A challenger has arrived on the hill!  Vital statistics:
   Program "Consumption" (length 100) by "Arno Fuhlendorf"
   (contact address "fuhlendo@rho.uleth.ca"):
   ;strategy  consumption be done about all these imps

S. Strack is proving that the NAME is everything in CoreWars.  His
'prototype' program consistently scores higher than the same code
put up as 'Agony'.  Just part of the fun, right Stefan?  (Uh-Oh again,
latest standings put Agony 5.0 solidly on the top!)

A. Pierce put in an appearance this week.  Giving 'Twill' a try, Andy?
Got to make it imp-proof :-)

U. Koistinen!  Do not give up so easy!
    Program "Impkiller 0.2" (length 8) by "Urban Koistinen"
    (contact address "md85-epi@nada.kth.se"):
    ;strategy 1. Bomb with spl -1
    ;strategy 2. Bomb with dat
    ;strategy 3. coreclear
    ;strategy 4. kill self

Hey, Albert Ma, leave the removing to the competition!
    Program "testimp" (length 45) by "Albert Ma (stone by P.Kline)"
    (contact address "ama@Athena.MIT.EDU"):
    ;strategy just testing the viability of imps on hill
    ;strategy imp launch is my own (reverse engineered)
    ;strategy stone is from Imprimis 6
    ;strategy if this actually makes it on the hill
    ;strategy I will remove it.

  V.  The Quick Look:

-------------------------------------------------------------------------------
 VI.  The Hint:

    Optimal-shmoptimal.  Dan Nabutovsky is using 7 as a bombing increment
step with great success in Moonstone.  There really is a lot to be explored
out there.
