I heard about a pro comment that the Great wall and similar openings are quite feasible, but also quite easily thwarted. If you opponent plays it, you just prevent him from completing it by taking the last point yourself. This should give him an inferior position. If you let him complete it, he probably has a superior position. Dave

Ki Press; 1996. I can only recommend it for the many fresh ideas. A few days ago I found time again to read in it. This time I was impressed by Bruce Wilcox's strange opening "Great Wall", where Black starts with a loose wall made of 5 stones, spanning over the whole board. Bruce proposes to play this setup as a surprise weapon, even against stronger opponents. Now I made some autoplay tests, starting from the end position given in the appendix of this mail. * one game with Leela 3.16; Black won. * four games with MFoG 12.016; two wins each for Black and White. So there is some indiciation that the Great Wall works even for bots, who are not affected by psychology. I would like to know how other bots perform in autoplay after this opening.
