It seems xboard now has a new default hash memory option. Polyglot would send :-
But earlier my engine received:-1312393771.993 GUI->Adapter: accepted option
1312393771.993 GUI->Adapter: accepted done
1312393771.993 GUI->Adapter: memory 68
1312393771.993 POLYGLOT setting the amount of memory to 68Mb
1312393771.993 POLYGLOT Nalimov Cache is 0Mb
1312393771.993 Adapter->Engine: setoption name Hash value 68
which is under the UCI option section of the polyglot .ini file.1312393771.993 Adapter->Engine: setoption name Hash value 256
So my engine finally only set hash memory only to the default from xboard. I think other engines should be affected if they run under polyglot.
Rasjid.
