Go up one level in this thread


Shalom Uri!
I don't look for excuses to weakness of Rybka in endgame : I just notice that in
endgame its depth is curiously low , compared to fast engines as Junior or
Shredder : these increase their depth in endgame , as Rybka decrease it
You know as well as me that Junior7 has almost no endgame knowledge , and yet it
performs very well against Hiiarcs in endgame , chiefly because Hiarcs has not
enough time left to analyze deeply
Do you find normal that , in endgame ,Rybka analyze only to depth 10 , as its
opponent analyzes up to depth 17 , and why? because it is in Zeitnot
It happens precisely against the engines that seek complications in middlegame :
Rybka performs much better with those which accept simplification
