Yace could not refute Be2 at depth 17,18 New game - Junior 7 2kr3r/p1p2pbp/1p2b3/2p1Pp2/2P2P2/PPN1K3/6PP/2R2B1R w - - 0 1 Analysis by Yace 0.99.56: = (-0.10) Depth: 17 01:23:23 2563254kN 22.Bf1-e2 f7-f6 23.e5xf6 Bg7xf6 24.Be2-d3 Rh8-e8 25.Ke3-d2 Kc8-b7 26.Kd2-c2 c7-c6 27.Rh1-e1 Be6-d7 28.Re1-h1 Bf6-d4 29.g2-g3 Bd4-e3 30.Rc1-d1 a7-a5 31.a3-a4 = (-0.10) Depth: 18 02:12:25 4114307kN (Blass, Tel-aviv 08.10.2002) I stopped the analysis Maybe yace(no material) can find something at depth 19 but it is time to give normal chess programs to calculate to find what they can find. Normal yace understands nothing after a short search but maybe longer search can help.
