Yes. To check this, I just downloaded KQBKQ tables. For 149. Kb4 Crafty had shown -4.6 (about the same as for the 45 last moves). For its 150th move, Crafty had shown -Mat10, for its 151st move -12.36 and for its 152nd move 0.0 (after which black still can mate). >After that DTC- and DTM-optimal play mate on Black's move 155 which does indeed >wrap up the game for a win with exactly 100 plies in the last phase. > >Was either side playing with the DTC- and/or DTM EGTs? Both engines had acces to all 4-men tables (distance to mate). Regards, Dieter
