So I generated then with some restrictions: * Have at least 50 legal moves in the last position of the line * Restricted maximum ply to 14 * Each move of the line doesn't have a CAP Score (CAP was such a really cool project!!) less than -.50 or more as +.50 * My line generation out of my book should automatically omit doubles 1.d4 d5 2.e4 e6 3.Nc3 dxe4 4.Nxe4 Qd5 5.Nc3 Bb4 6.Nf3 Nf6 7.Bd3 [51]
