Subject: Junior 7 - very strong indeed but .....

I use chess software not so much to play against them, nor play them against
each other, but rather to use them as engines within Chessbase to analyze games.
 I have been doing this for at least 8 years and believe that I am not too bad
at this.

My hardware is an Athlon 1.2 gig 512 RAM, and until recently my favorite
analysis partner has been HiArcs7.32

Fritz used to be my favorite, but I have been dissatisfied with it ever since
they came out with Fritz6.  With all the additional knowledge they put into it
they also seem to be "dumbed" down its tactical alertness.  It started missing a
lot of tactical shots which is crucial if you are studying a particular opening.

Talking about tactical shots Gambit Tiger 2.0 is awesome, but some of its
positional evaluation is greatly suspect.

I believe Shredder 5.32 should only be used in the endgame.  In the opening and
middlegame its tactics is VERY bad.  In the endgame, though, I have no
reservations about stating that it is in a class by itself.

Junior 7, I am happy to say, has impressed me very much both with its tactics
and positional soundness.  If it were not for the two problems given below I
would instantly recommend it to any of my students (both of the problems are
when you run it as an engine within Chessbase 8) :

 1. If you are analyzing a position and then decide, for example, to do another
operation, for example open a book window to check whether a certain move has
been played before, oftentimes it would crash.

 2. So the best thing is to close the analysis window first before accessing the
book window.  Problem is, it takes forever to unload the junior 7 engine.

I use 184 MEG hash tables, and maybe decreasing the hash would make it "unload"
faster, but the other engines have no problem with unloading and of course you
would want to make use of the maximum power available from your hardware.

Anybody else have a similar experience?
