That must be wrong if the scores are from Arena. Arena shows the given value/100. Now this could be the end of story but it isn't... Skaki sends 10000 as the mate value and Arena does something very strange here and translates it to 31900. It is Arena who selects that value! Skaki uses 10000. >But you think it is an expression of Mate in 1 with a value of 31900? It should be :-) >Why 31900? Well, in the winboard protocol there is no standard for mate values. The engine can select any value as mate, normally something very high. Many engines have 32767 the hihgest possible signed 16-bit value in town. 31900 is as good as anything here. Terra uses 30000. Now, this time Arena made his/here own choice as explained above. >I'm just wondering why? > >Any ideas? > >Also do you have a copy of Averno 0.2x?
