That value doesn't learn you much. If it picks a suboptimal solution, it may find a mate in 100 somewhere in the tree. You can get nearly the same info now by looking at 'MaxDepth', which is the deepest line it visited. Since it was 27 ply, the mate it found cannot be deeper than 13 moves. This does not mean there cannot be a shorter mate. -- GCP
