Although I cannot give a definitive answer, I have often used several different
engines to do automatic analysis, [which I call "overnight analysis" since I
typically have the program running at night while I'm sleeping,] of  a serious
game.  Generally, Shredder seems to give the best results most of the time and
Fritz second.  Junior behaves like a wild horse, often diverging widely from the
other engines.  Note that a PV is ***NOT*** displayed in this mode.  Analysis
lines presented in such analyses are not PVs.

For analysis with the human present, Fritz is my choice since Shredder still
appears to have a credibility problem with it's PV.  When I'm sitting in front
of the computer screen, I use infinite analysis mode.
