We have an experimental version that uses knowledge from my old program
Explorer in Fuego.
It gives a bonus in terms of a number of won simulations to moves considered
good by the knowledge.
As shown in one of Guillaume Chaslot's papers, you can run expensive knowledge
in "heavy" nodes in the tree which already had many simulations, since there
are not many of those.
We have positive results for three types of knowledge on 19x19. Nothing worked
on 9x9 so far.
1. tactical search - give bonus to move capturing/saving unsettled block of
stones
2. patterns - give bonus to moves proposed by Explorer's hand-built library of
patterns (about 4000, irregular size and shape)
3. move filter - hard-prune a small set of moves that Explorer would also
hard-prune
With each of those in isolation we have 60-70% wins against plain Fuego in fast
games. We do not know a good combination of the three, since the current
implementation does not allow us to run more than one such extension at a time.
It is not hard to generalize, but we have not done it yet, and it would need
testing/tweaking of parameters.
