 ICC account names that differ from the program name:
 ----------------------------------------------------------------------------
 ArasanX (Arasan), jlong (Galahad).

Notable

LambChop tops the list this week, at 2586.  Interesting to note that LambChop
runs on a P133, while Chopster (P3/500) and Beadle (P2/266), running the same
program, are rated 2590 and 2585, respectively.  This probably shows the
importance of opponent selection, since their formulas differ.  And, too,
blitz ratings can swing a lot.  But the fact that the three accounts are
within 5 points of each other is remarkable.

Hossa was again the most active program, while Rajah made the largest gain
with 123 points.  Also gaining quite a lot was Galahad, and based on some
of its games this week, I expect similar gains in the future.

One new high wes recorded, by Galahad (2462).


Changes

Rookie goes inactive.

u2600 Position of the Week

This is from the game Amateur-Phalanx21 (pikozrout), played this week on
fics.  The correct move is an intuitive choice for humans, and likely for
some programs.  Even if yours likes it initially, see how long it takes for
the score to jump up.  (Ne4 was played in the actual game.)
