i don't think that g4 alone is the mistake.
the problem in my opinion is the fact that fritz always has draw
scores.
if you are attacked by your opponent, and all you see is draw
scores, then you don't need a search.
you can replace the search by ONE line:
evaluation :=0.00;
what YOU call mistake, move 41.g4
is only the last mistake.
look:
The draw-score moves: 29,30,31,32,33,34,35,37,38,39,40,41 shows exactly the area
Gambit-tiger gets the evaluation increase.
all the listed moves before, have nearly draw scores !
and now look at gambit-tigers scores in the same time:
this gambit-tiger score sees the plot.
this "behaviour" is in fritz for many versions.
it was world-championship paderborn and it was in other
situations. i guess they cannot fix it, otherwise
they would have done it much earlier.
it must be a major problem. if they would fix it,
fritz would lose strength.
you can forget fritz in those situations. it is BLIND !
guess a boxer, rocky, part V, suddenly gets blind
from minute 29 to minute 41 !
what would happen ? knocked out !
and that is what gambit-tiger is doing with fritz.
how do you want to use an "often blind" program for analysis ?
how do you want to win a tournament or championship with a
blind program?
it makes 400.000 NPS or even more. say 1.000.000 NPS.
and as a result you can replace all the Nodes by:
evaluation:=0.00;
no.
fritz seems to see draw by repetitions for black !
it believes: black is weaker, therefore it would like to draw.
and the best i create some fresh draw lines.
it computes 500.000 NPS to find out NOTHING about the position.
that of course the reason there is no fritz7 on the market.
they can't bring it out. it would lose to gambit-tiger.
thats the reason the latest computer-schach and spiele
has nothing about fritz and much about shredder5.
because fritz is losing against gambit-tiger by
2xn to n (with n=number of winning points) against
Gambit-Tiger.
they HAVE no product. they had one, but when rebel was released
they had none. so they now try to adapt.
but how to fix something they have been unable to fix
for many versions. the "bug" was in fritz6, in fritz5.32,
it was in fritz4 and in fritz3.
this shit draw-behaviour is part of fritz' strength.
how to fix it ?!
they can only operate the beast and stand the opponent
making jokes about their program and about the draw-score.
making a bored face when opponent puts a finger on the draw-score.
thats all they can do.

How shall fritz6 win or stand games it shows NO IDEA about what happens on the
board ?!
In move 37. It even believes it is better again. In the moment is sees the
problem (move 41.) it is too late and it loses very fast.
The draw-score moves: 29,30,31,32,33,34,35,37,38,39,40,41 shows exactly the area
Gambit-tiger gets the evaluation increase.
In the moments Gambit-Tiger SEES and idea and evaluates it, Fritz sees only
Silly draw-scores or scores nearly sero.
