Sometimes, being simple-minded gets you into great trouble, like my analysis
yesterday.  (By the way, I have analyzed every position in the game at 400
seconds and am going to reanalzye the interesting ones at long time control).

Anyway -- lowly Beowulf gobbled this one up.  Of course, it does not see any
great advantage, and only has the pv right for the first few moves. (analysis
out to 148 seconds)
