I've puzzled over game 2 a bit, because coming "out of book" a pawn down
really made no sense...  When we started this match, we started off with
the idea of level 0 120 180 (2 hours on the clock, 180 seconds added after
each move.)  I wanted to run Crafty in "tournament mode" and with "book
random 0" (which says search the book moves and ignore any that lose
material or have bad scores).  Since I couldn't make this the default and
leave it logged on, I chose to set those inside crafty when it noticed
"level 0 120 180".  Of course, after game one, Mark and I agreed that the
time control was *way* too long and reduced it to 30 180...  But yours
truly forgot to change the code that sets tournament mode and book random 0.

Which at least explains how Crafty could leave book at -1.5...  I found
it this morning after game 3 had started..  and have corrected the "patch"
so that crafty should generally not fall into a -1.5 hole.  I can't do this
for "normal" server games because the search is deterministic and would play
the same move every time, which is sure death.  :)
