Why not start with the 5-vertex cross pattern? Going from 1x1 to 3x3 is a huge jump in complexity and debugability. With 5-vertex patterns, you can enumerate
the patterns on paper (there are around 3^4 == 81 of them, ignoring symmetries) to sanity-check the details and see if the general idea works at all. There are
too many to enumerate with 9-vertex 3x3 patterns (around 3^8 == 6561, ignoring symmetries).

Yes. I think it's a good idea, but the devil is in the details. I've
become pretty disenchanted with trying to use 3x3 or 5x5 patterns.
Currently, I have about 300 1x1 patterns (I call them context codes)
that I'm playing around with.
You can also do the same for RAVE without needing any more memory. You
only adjust the RAVE values, at a node, after filtering out moves, in
the playouts, that don't match the context/pattern for that position at
that node.

Subject: Re: [computer-go] 1x1 patterns?!
I had never considered using AMAF with larger pattern. That's an
interesting idea. Perhaps a 5-vertex cross-shaped pattern or a 3x3
pattern. Has anyone tried this?
