Subject: wrong evaluation by Fritz 6a

Hi fellow CCC-ers

I played a blitz game on FICS and came in this lost position.
Analyzing afterwards supported by Fritz I found out Fritz gave the following
evaluation:

OhWellOkay - Jeroen
[D]3R4/p7/1pb1k3/4r2p/4p1p1/2P3P1/PP3P1P/4R1K1 b - - 0 42

Analysis by Fritz 6:

1. = (0.00): 42...Kf5
2. +- (2.22): 42...Bd5 43.b3 Ke7 44.Rh8 Bf7 45.Rh6 Kf8 46.Rd6 Rd5 47.Rxd5
3. +- (2.25): 42...a5 43.Red1 Ke7
4. +- (2.41): 42...Ke7 43.Rc8 Kd7 44.Rh8 Rd5 45.Rh7+ Kc8 46.Rxa7 Rd2 47.b3

Of course after playing Kf5, which I actually did, the assessment is

OhWellOkay - Jeroen
3R4/p7/1pb5/4rk1p/4p1p1/2P3P1/PP3P1P/4R1K1 w - - 0 42

Analysis by Fritz 6:

1. +- (2.31): 43.Red1 Re6 44.Rh8 Kg6 45.h3 gxh3
2. +- (2.16): 43.h3 gxh3 44.Kh2 Rb5 45.b4 Kg4 46.Rg8+ Kf3 47.Rf8+ Kg4
3. +- (2.16): 43.h4 gxh3
4. +- (2.16): 43.Kf1 a6 44.Rf8+ Kg6 45.Rb8 Re6 46.c4 Ba4 47.b3 Bd7


Why does Fritz give the 0.00 evaluation without a further suggested line and
switches to normal evaluation after playing 42...Kf5?
Any ideas, or is this old stuff?

Thanks for your reactions.

Jeroen ;-}
