Endgame-Weakness by Stockfish 1.8!

Ich schreibe auf deutsch (sorry) damit ich schneller fertig bin. Mit einem englischen Text würde ich sehr lange brauchen. Ich bitte darum um Verständnis.

Ich spielte mit Stockfish 1.8 auf Playchess (with my second account Solist) einige games (nur wenige Games!) aber 3 von diesen wenigen games, hat Stockfish 1.8 wegen seines schlechten Endspiels verloren!! Hier 3 Beispiele.

Game 1:

Mein Kommentar: Anstatt hier wartend auf Remis zu spielen, spielt Stockfish 1.8 76. d5? (oh NOOO), und nach 76...c4!! war die Partie für Stockfish 1.8 sofort verloren!

Game 2:

In der folgenden Partie stand Stockfish 1.8 mit Schwarz sehr gut, aber im Endspiel verlor er die Kontrolle, und hat ein Spiel verloren, das man normal nicht verliert! (Oh NOOO).

Position after move 66:

Stockfish 1.8 spielte hier fatal 67. Bxf3?? (oh NOOOOOOOOOO!) und das Spiel war sofort verloren, wie man sehen kann!

Warum spielt Stockfish 1.8 im Endspiel so schlechte Züge?
Why try Stockfish 1.8 in the endgames so much bad moves?

ED.

PS: In the last 2 games I played with "Mobility (Middle Game)=105."

OK, hier ein Spiel (das letzte bisher) das Stockfish 1.8 soeben gewonnen hat:

Re: Endgame-Weakness by Stockfish 1.8

In my example with game 1, Stockfish played real 75. d5??

Here is a analysis by Stockfish 1.8 w32 on my core 2 Duo 2.66 GHz. You can see that Stockfish cannot see that after 75. c4!! - game is lost for white! :(

(Nemeth, Privat 03.07.2010)

And in my last example (that with Bxf3??), yes, on playchess Stockfish played this incredible move! :(

I am not lucky with this version of Stockfish 1.8, sorry. Here is in the engine anything (hash or something) wrong!!

Stockfish 1.8 loses on time with a draw position (on playchess)!

Please, I need a "time management" (time buffer for playchess!).

German (original):

Du hast Recht, aber so ist es ein sehr schmaler Weg zum Remis, du musst ganz genau spielen!

Einfacher und easy war axb5.

Insgesamt: Stockfish 1.8 macht bei mir keinen guten Eindruck, weil die Bewertungen von Zug zu Zug, zu sehr schwanken.

Ich muss darum Klartext schreiben, denn was nicht gut ist, sollte man nicht schön reden!

English (bad translate):

You're right, but it is a very narrow way to draw, you have to play very well! Simple and easy was axb5.

Final: Stockfish 1.8 makes me a bad impression, because evals from move to move, vary too much. I have to write about plain language, for what is not good, you should not talk about beautiful!

Hello!

Frank Quisinsky wrote in german CSS Forum

http://forum.computerschach.de/cgi-bin/ ... ?pid=28007

that Stockfish 1.8 32-Bit is ~20 ELO weaker then Stockfish 1.7.1!! :roll:

That is not a surprise for me, see my games in this thread!!

Now Frank is testing a 1.8.0a (Beta) get from Programmer.

That are now good news for me and (I hope) for SF too.

20 ELO weaker than SF 1.71?! In my opinion that's not confirmed. I'm reading conflicted reports suggesting it's actually 20 to 30 ELO better than Stockfish 1.71.
