A little bit about SOS:

"SOS is an amateur program which was started in 1993 and has since then competed in a number of tournaments. The newest version runs on multiprocessor systems with a parallelized version of mtd(f) as its minimax search algorithm. SOS used to be a relativley fast searcher and relied on outsearching the opponent. This has changed now and more knowledge and special cases have been implemented which slow it down. Little effort is spent on the opening book. It plays a very broad range of openings. However it learns to avoid unsuccessful lines and tries not to repeat lost games. It uses publicly available endgame databases."
