example of a strong renewable
Zack Brown
I just finished this game with a friend of mine:
1)
2,1VW
1,3HS
2)
0,1HNE
0VENN
3) 4,2VWW
3VWN
4)
2HN
0,3VES
5)
3HNW
3,6HS
6)
2,4VEN
3,3HN
7)
0,6HS
6,4VW
8)
3,9VW
5,4VE
9)
6,5VW
3,5HS-W
10)
3,9,1H2-2S-S
6,3VW-NW
11)
3,9,1V2-1E-ES
Basically, as soon as the renewable comes into being, the game is
over. This is partly because black already connects 3 sides in a
virtually impervious way, and partly because the threat to win can't
be defended while simultaneously destroying the renewable.
If you look at the position when black swapped the piece over to
construct the final renewable, the win does not look at all like a
done deal. I'd guess that black has a significant advantage, with such
a strong connection against the West wall; but it's hard to poke
through to the other side.
So in this case, white had to stop the renewable before it got
started. So instead of capturing black's two rectangles with
9) ... 3,5HS-W
it was necessary to do something about that renewable on the upper
edge. So maybe after
9) ... 3,8VE-NE
10)
6,4HNWS
5,7HS
Now white is still threatening to capture the two rectangles from
before, and has another threat to capture the string of pieces to the
right of those. White has also connected three sides, making it a
stand-off position. All the big white squares in the middle of the
board are now either impervious, or easy for white to swap back into
with material gain. Black still probably has the advantage because of
the strong West wall, but there's still plenty of play left in the
position.
So just by allowing that one strong renewable, the position was an
immediate loss for white. That's how it seems to me.
Be well,
Zack
