Matacz 1.02 : draw detection bug ?

[Arnaud Lohéac]

Hi Maciej Pestka

i think there is a problem of draw detection with Matacz.

After 3 repetitions, the engine stops playing, without announcing draw and then loose on time

This game was played under the new Arena 1.99 beta 1.

White are loosing here on time instead of claiming draw.

Here is the debug file for the last move of Matacz

I hope this could help :

This Arena beta bug was already reported either in the Arena
or in the Schachwerkstatt forum.
They suggest not to use that beta for games yet.
