Hi,
I have to face this problem:
When using aspiration search at the root with window <eval-100,eval+100> I
occasionally get fail high - for example when I have found a mate. Problem
is when the returned score (let's call it S)is actually the exact value of my
position - in this case I do a research with window <S,+infinity> but
I'm unable to set PV properly at that ply - and if it's last ply of the search
PV is wrong... (e.g. showing PV not leading to mate even though returned score
says it will be mate...).
I set the PV in the tree when:
1) I got cutoff
2) eval()>alfa
Thank you in advance for your suggestions.
