If you mean Fritz 8X3D, I would agree that it's not strong enough because it was
the earliest version, but I prefer analyzing with Fritz 1.2.0 (Bilbao) or Deep
Fritz 8. They are more sophisticated than the predecessor. Of course, the style
I use (developing complicated acute positions) may count too, but on the whole
I'm quite happy with DF8. As a proof I can present a position arisen in ICCF
WS/M/003. What we'are having now, is a complicated endgame.
The game is still going on but I'm sure it's dead won, so I'm giving it now.
[D] 7k/3r4/2rN1p1p/2P4P/1P1p4/P2bpKR1/6P1/2R5 w - - 0 56

I've analyzed this endgame with different engines (Shredder 9 UCI, Fruit 2.1,
Hiarcs 9, Fritz 8 Bilbao, Deep Fritz 8) but it's only DF8 that produced the
correct easy winning move sequence: 56.Rg4 Rdxd6 (56...Rcxd6 changes nothing
much) 57.cxd6 Rxd6 58.Rc8+ Kh7 59.Rc7+ Kh8 60.Rgg7! +-
I don't know, if the hardware counts here (Celeron 333/128MB RAM) and with the
better hardware other chess engines would also find the sequence, but with what
I have this engine seems to work best of all. The other engines proposed 60.a4?!
as the best move.

Kind regards,
Alex
