Notable

We saw some large ratings variations this week, with Hossa taking the top
spot away from TDchess.  In fact, two programs have broken the 2600 barrier,
Hossa and PostModernist.  Congrats to Steffen and Andrew!

New highs were reached by Hossa (2638), PostModernist (2607), and
TDchess (2775).  TDchess lost almost 300 points from it's high on March 25,
but was also the games-played leader with 384.  There does seem to be some
correlation between games_played and rating swings, though some programs
are more susceptible to this than others.


Changes

Stobor rejoins the active list, BugChess and Pedestrian go inactive.


u2600 Position of the Week

This comes from a 30 0 game played on ICC this week between GM Wilder and
Ferret.  Wilder, playing white, has given up the forced draw to try for a
win, which he apparently sensed was there.  It looks like he was right, but
he did not find the move, which was 45. Rh8+!
