Yes, once you get used to the speed, CB really can cause one to want to tear
one's hair out. I once was getting ready for a tournament and thought of fitting
a CA tree on one CD, and a CB tree on another. The CA tree, from a 1 million +
game DB took about 30-40 minutes to do, then I came around to CB: the first
thing it told me was that I didn't have enough hard disk space. I was surprised,
and checked only to see I had about 1.5 Gigs. Astonished, I split the DB (about
1.1 million games) in two and had it start. 10 hours later it was still
going.... I kid you not. Both of these were done on a K6/233 + IDE HD at the
time.

Of course, but it is annoying enough to be a problem in my case. I suspect it
has to do with two things:

1) The type face I am used to seeing in chess literature tends to look much more
like that of CB hence the matter of familiarity.

2) The lines that determine the shape of the pieces are very thin so that the
pieces don't stand out quite as clearly.

Naturally, this may all be just me, but I believe that where one person
complains about it, there are ten other silent miffed ones as well.

Perhaps this was a memory problem. At the time I used 32 Mb, and though Rebel
would indeed load fairly quickly, the minute I had it start analyzing, the HD
would go crazy for about a minute before Rebel even gave the results for its
first ply.

I think it should be possible to sort them out.

I don't see why CA could not handle all aspects (except for the multimedia) of
reading/converting .cbh files perfectly. Aside from the pawn-structure symbol,
which causes a small window representing the pawn-structure to appear in
commented CB games, there isn't anything CA doesn't have as well:

- colored arrows and squares in order to highlight moves or squares.
- timed moves... Actually, CA doesn't actually have it, but it is amply used in
all of their training products, so I imagine this would be a simple thing to
include.
- Notation symbols describing the moves and positions.
- Themes: strategical, tactical, etc...

The only thing I still regret is the lack of follow-up on the other programs
such as Strategy, Studies 2.0, etc... These had PGN notation problems which were
eventually sorted out by CA4. These also didn't allow one to use any other
engine than Dragon, despite having Zarkov 4.2 (used by CA3), or the Craftys also
used in CA4. This detracted a lot from them as part of the whole idea was to be
able to train with specific positions against the computer, only, in this case,
it was literally impossible to play against any opponent other than Dragon, or
an external program (no later than Rebel 9). I had wanted to play against Fritz
and Hiarcs (CB) but the PGN notation problem made this impossible. The board in
Strategy was already very limited as it looked absolutely tiny on my screen in
1k x 768 resolution. Again, a small patch to correct this should have been
possible.
