Here is the output of CSTal (k5/100 Mhz), commercial version, in the position AFTER Nxe4 by fritz5. You see that cstal does not consider Nxe4 at any place. Therefore I posted the game as an example game where Fritz5 made a WEAK-move (from my personal point of view). IMO human chess players would not take on e4 since this makes it possible for white to pin the knight. Fritz and also other programs do this. Although they are good in finding tactical key-moves in other positions, they fail here. 000:02 2263n/s d1 +0.96 a8d8 b1b3 b5c4 d6d8 e8d8 d3c4 f6e4 b3b7 NULL 000:02 2518n/s d1 +1.04 b5c5 b1b3 b7b6 f3d4 NULL 000:02 2914n/s d2 +1.04 b5c5 b1b3 b7b6 f3d4 NULL 000:03 2390n/s d3 +1.04 b5c5 b1b3 b7b6 f3d4 NULL 000:06 2278n/s d4 -0.05 b5c5 b1b3 b7b6 f3d4 c5d6 c4d6 e8e7 d6f5 e7d7 f5g7 NULL 000:10 2137n/s d4 +0.79 a8d8 b1b3 b5c4 d6d8 e8d8 d3c4 d8c7 NULL 000:18 2128n/s d5 +0.75 a8d8 b1b3 b5c4 d6d8 e8d8 d3c4 d8c8 NULL 000:42 2069n/s d6 +0.75 a8d8 b1b3 b5c4 d6d8 e8d8 d3c4 d8c8 NULL 002:38 2052n/s d7 +0.75 a8d8 b1b3 b5c4 d6d8 e8d8 d3c4 d8c8 NULL 007:29 2057n/s d8 +0.89 a8d8 b1b3 b5c4 d6d8 e8d8 d3c4 d8c8 e4e5 f6d7 f3d4 d7e5 NULL When Fritz5 played Nxe4, the output of CSTal was the following, instantly the evaluation sees the win...

As a result or answer on my post Enrique and Moritz posted strange posts with unmotivated games were cstal loses. I don't understand this kind of "answer". My example was an effort to answer on demands by people of this club to show weaknesses in fritz-playing. I think this game was a weakness. I did not CONSTRUCT or PRODUCED this game to attack fritz or moritz or enrique. In fact this game was played 2 days ago, and since it shows a weak move, I thought - why not posting it to express my personal and subjective point of view. I am afraid of the kind of reaction by enrique and moritz. I would have wished that people replay the game and maybe try with their own programs (ferret, crafty, mchess, junior, chesstiger, diogenes, comet, ...). Instead enrique and moritz felt the need to "answer" in a reflex with losses of cstal (in a kind of automatism he instantly turned my example and showed HIS example in the same headline, just replaced fritz5 with cstal. I have shown that the example he chose was not well chosen since the game he posted was mainly determinated by the opening and the non-trivial-temptation Bb4.) and claims of results and calling this example worthless and cherry picking and and and. Why do we have to do this. Moritz even tried to link my post of a weak position with rgcc and a 1.5 years campaign of a guy from there. He began with the statement to analyse the game, and suddenly linked this with rgcc topics. Isn't it possible to discuss in a normal way ? Is it legal to misuse my example game to relate it with a guy who called other people 1.5 years long all kind of nasty-words ? I am shocked that moritz and later also enrique tried to suggest this. IMO this cannot be related, and I will not accept this. not as a member. and not as a friend.
