Intel Q9550 2.83GHz Quad, LittleBlitzerGUI, 256 MB Hash, 1 Core per Engine, no ponder, no bases, no resign. 50 super-short test-positions (1.a3 a6, 1.a3 b6, 1.a3 c6…..1.h3 g6, 1.h3 h6) = Naked Engines (no openings (book or long test-positions (Noomen etc.)), no endgame-databases) – only engine-thinking from move 2 until mate or draw.
Two lists with exact same conditions except the thinking time. That makes it possible to see, which engine scores better or worse with more or less thinking time...
