Based on score the computer makes decisisions. In the position i show, there is no horizon effect, nor deep down the variation a trick. In a 3fold repitition Tiger may show -0.16 but not -2. THis is definately a wrong evalutation. When i play Kd5, or Qd3 it goes to 0.0 at once , so there must be an algorithm problem. (dont know terminology, smthg like fail high..) but definately smthg is not ok.
