You mean you do not yet have the IM title.  In my book, however, anyone with
2200+ ELO is playing at the master level in "slow" games.

Then there are those who play 2400+ in ICC Blitz &/or Bullet.  I don't know how
to catagorize them.  : )

I find it convenient to have my chess engine analyze my games overnight or while
I'm away.  That seems to give better results.  Especially nice is the feature of
Fritz to adjust the analysis parameters.  If only one game is to be analyzed,
Fritz can be asked to do a much more thorough job than if numerous games must be
analyzed overnight.

Later, I very quickly go through the overnight findings just to get a "feel" for
what was discovered.  Then I select that which I will study more closely.

As for "forgetting one's game":  Before I retired from tournament chess, I
played many serious over-the-board games lasting from four to eight hours.
That's a lot of mental effort!  Those games I did NOT forget.  Nowadays, my
chess is limited to blitz, and I play only rarely.  In my view, Blitz is a
legitimate form of the game.  It would be nice to play 2400-level blitz at ICC.
I use the computer to identify my blunders in blitz so that I can become better
at playing blitz, and not so that I can become better at slow chess.  Recently,
I played 60+ blitz games after several years of inactivity.  They were filled
with blunders.  These are what I'm looking at now.  Hypothesis:  If one wishes
to get better at blitz, one must purge the blunders out of one's blitz games.

For the last several years, I have limited myself to in-depth analysis of GM
games.  Also, I used to enjoy creating new opening repertoires.

The above gives an overview of a "user's" use of chess software.  Perhaps other
users have different uses for the software.
