blockquote, div.yahoo_quoted { margin-left: 0 !important; border-left:1px 
#715FFA solid !important; padding-left:1ex !important; background-color:white 
!important; } I speculate: nakade involves creating a shape (such as three in a 
row or a bulky five) such that, if captured, it would only form one eye, given 
the proper placement. I can imagine a set of patterns which enumerate the 
possibilities. Some examples exist, however, which are quite complex.

I am trying to re-create the fast rollout policy as described by deepMind but 
got stuck on the nakade patterns:
"Nakade, # of patterns 8192: Move matches a nakade pattern at captured stone"

the "at captured stone" confuses me, my first thought is: "this is only 
computed if stones have been captured recently" but i don't think that is 
correct. how should i read it?
since they say "# of patterns 8192" i imagine they found some way to hash them 
just like the 3x3 and 12point diamond shapes but so fari have not found a way 
to do so. I found that other engines use heuristics to find nakade patterns so 
my question is does AlphaGo use patterns and does somebody know how this works?
Thanks!
