A few months ago, we were told by Bill Worley from HP Labs in California
that Grand Master David Bronstein would be at their Labs and David would
be interested in playing casual games with DT.  We suggested that
a handle be created for David and the games be played over ICS.  We
were expecting to play the games in peace and quiet without much fanfare,
but word got out and the games became daily spectacles on ICS for a while.

DT II was being modified for further software work when the games were
started, and not available for the first 7 games, which were played by
DT I.  There were quite a few problems with the ICS setup in the early
games.  David played the games on his own board and an operator (Mr. Bob
English) operated the ICS interface for him.  Bob was using the ASCII
interface for the first 3 games, and a few operator errors were made.
XICS interface was used afterwards.  The lack of a running clock display
in the current XICS interface might have contributed to David's time
trouble (any programmer listening?).

The final tallies are favorable for both DT I (5 wins, 1 losses, and 1
aborted [operator typo, objectively David should have won]) and
DT II (8 wins, 1 draw, 1 loss, and 1 aborted speed game [typo again]).
However, the tallies do not tell the whole story.  The first two wins
by DT I were probably more due to operator overhead (fast games, ASCII
interface and first time operator).  David was recording his thoughts
on a tape recorder during the games, which at least should be regarded
as an X factor.  Furthermore, David was apparently more interested in
creating "fun" positions than worrying about winning the games.

The games themselves were all quite exciting.  I should have been
spending time working on the new machine, but ended up finding myself
glued to the tube watching the ups and downs of the games.  Personally,
I am amazed at David's wild but logical imagination.  The old warrior
showed that he still had the magical touches.  In all of DT I's games
and quite a few of DT II's games, David had winning positions at some
point.

Below are the games.  Sorry that DT I's games are in a strange format.
DT II's games are in standard algebraic.
