Another 22 characters shaved off:

#!perl -ln0
$:='((?=W|.{9}W)|(?<=W.)|(?<=W.{10}))';{1while s/w$:/W/s;/ $:/gs>//gs&
+&print+("@-E-1"+1)=~y/./ /r;y/W/x/;s/w/W/&&redo}

EDIT: Down to 109. I’m starting to like it, but we can likely get this under 100.

#!perl -ln0
$,='((?=.(.{9})?g)|g(.{9})?\K)'until!s!$,w!g!s;$,=/$, /gs>//gs&&!map!y
+!.! !>print,"@-e-1"+1;y&g& &&&redo

EDIT2: While my first solution was correct, both solutions in this post have the same problem: if playing a single black stone captures multiple white groups, this move is printed multiple times. Here’s a 127 stroker that prints each move only once:

#!perl -ln0
map{1while$,=s=$,w=g=s?'(g|(?=.g|..{9}g)|g.{9})\K':/g/>/$, /s&&map{y!.
+! !;print;redo}/x/+"@+E-1"or y&g&b&}"$`x$'"while/ /g

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
