Not really a compuetr Go issue, but I do not think that great wall is
superior even when completed. It is not too bad but it needs a definite
strategy from wall owner. I.e building side moyos using wall as a roof and
hoping that the other guy gets nervous and jumps in. So by being patient is
pretty good defence against it.

But to computer go: It may well that MCTS programs have abilities that match
the great wall fuseki. They do like moyo's and fighting so this sound like a
god match, but i doubt that it gives any meaninful boost. Just fun for a
change.
