We estimate that the rank of WinHonte 2.0 is around 4–9 kyu. However, WinHonte, like other computer programs, has strengths and weaknesses that are different from those of human players. Therefore, human opponents will often be able to improve their results against the program by adjusting to its style.

The history of Go stretches back some 4000 years and the game still enjoys a great popularity all over the world. Although its rules are simple (see gobase for a comprehensive introduction), its complexity has defeated the many attempts done to build a good Computer-Go player since the late 70's Presently, the best Computer-Go players are at the level of weak amateurs; Go is now considered one of the most difficult challenges for AI, replacing Chess in this role. The complexity of computer-Go comes from the difficulty to evaluation of given Go board position and the huge branching factor.
