The NEBB-Rankingslists (Naked Engine Bullet and Blitz) now with Stockfish 2.2.2 (Intel-Compile) – much better than a usual bugfix(!!!):

Intel Q9550 2.83GHz Quad (no SSE support, Vista 64bit), 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. Elos calculated with bayeselo (fixpoint Stockfish 2.1.1 JA 3000 Elo).
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...
