Hi Dann, I am not to familiar with EPDs. Is there a way to store a position with multiple evaluations through opcodes (not only one single pm or bm)? I think : 1. the position plus 2. Shredder - depth 15 (or time 300) - bm e2e4 - eval 0.55 - second bm d2d4 plus 3. Fruit - depth 15 - bm d2d4 - ... all in one single line, and so on for each position. and in case it's possible, do you know a program which is able to read and/or produce such data ? Thanks Marc
