Ed... simply email hsu and ask him.  If you don't have his email, ask and
I can email it to you.  I doubt Hsu wanted to see it called "DB Junior" since
it obviously isn't.  I suspect the marketing folks thought that the "junior"
shielded it from connection with the big iron version.  But it does taint the
'DB Junior' name that was still producing performance ratings well over 2700 vs
GM players...

That is immaterial.  But rather than me explaining this for a second time,
simple contact Hsu.  You will discover that (a) it searches for less than one
second per move (computation time) no matter what you do; (b) it is a web-
based stateless interface with no repetition or game history.  There were
other things 'disabled' to make the 'stateless' facility work...  But ask
Hsu for more details and to feel comfortable with the things I have reported.
It only takes one email...

It isn't the 'real thing' unfortunately.  This is just another effect of
marketing types taking control of something for publicity, without regard
for 'fact'...  I don't think Hsu has had control since the _first_ DB vs
Kasparov match...
