I suspect that you did not give the engines enough time.

Some minutes are not enough for them and they probably need at least some hours and maybe some days to avoid Rb5.
Parent - - By Master Om (Bronze) [in] Date 2011-10-10 13:09
Ok. I got it.
What is the minimum correct amount of time i should give ?
Parent - - By Uri Blass (*****) [il] Date 2011-10-10 13:25
I guess that after 5 hours part of the engines are going to solve it.
Parent - - By Master Om (Bronze) [in] Date 2011-10-10 15:37

>5 hours


:confused::confused::confused::confused::confused:
i.e. you near about spend this much cpu time/engine in your corr games !!!
Parent - By Uri Blass (*****) [il] Date 2011-10-13 17:45
yes
In correspondence games I may use even more than 24 hours of computer time in some positions.
