SSDF had sense maybe 10 or 15 years ago. What is the reason for so prehistoric rating list??? Pleistocen era hardware, Houdini engine completly missing, just Stockfish 3 included...it is time for retirement
I would win against Stockfish 5 with Rybka 4. People absolutly don´t understand that you don´t have to be GM...you have to know engine weaknessess and have experiences with analysis!!!
