Chessbase is not like Chessmaster when giving full analysis. I know what you
mean about chessmaster, thats why I never really looked at this feature in
chessbase. Chessbase is much more in the style of chess Informant with not much
text at all. Very easy for us "old school" chess players to read and understand
as written text. Chessbase stays mostly with what computers are good at as you
pointed out above, but it will show you "of course not Nxf3?? and why.  I will
give an example below.

[Event "16"]
[Site "London m4  ;HCL 18"]
[Date "1834.??.??"]
[Round "62"]
[White "Macdonnell A"]
[Black "De Labourdonnais L"]
[Result "0-1"]
[ECO "B32/06"]
[Annotator "Shredder 7.04 (180s)"]
[PlyCount "74"]
[EventDate "1834.??.??"]


[d]3b1r1k/3P2pp/8/p7/2Q1p3/8/PP1p1pPP/2R1qR1K w - - 0 34

34.Qc5
[34.Rfxe1?? is not to be advocated because of the following mate in 2 fxe1Q+
35.Rxe1 dxe1Q+ 36.Qf1 Qxf1#]

Chessbase analysis of  move 34 Macdonnel - De Labourdonnais 1834. Chessbase is
saying it agrees with 34. Qc5 as the best move and give a simple "trap" to be
avoided.

This is just a quick example to address the point you made above.
