double-ladder breaker and flower

Post by macelee »

I am visiting Beijing. On the latest Weiqi Tiandi magazine there's an article commenting the following game with very interesting shapes:

:ws: is a double ladder breaker - it also aims at the cut at 'a'. :b1: managed to defend both sides. But the game developed into a very interesting shape as follows:

This would be a really great position to ask someone "This is a real game. How do think did it happen? Show me the last 7 moves" And I think it would be even possible to solve :)

Interesting game mace. However I was unable to download the sgf from go4go because it's one of your special source games or whatnot. However the only reason I want to download it is to replay it on my phone with a program with next move buttons big enough for my fingers to tap (I use Agora); both the eidogo and go4go viewers are too small and fiddly on a mobile (Samsung Galaxy S3). It would be great if you could make the viewers more mobile friendly, an easier idea than a full-blown responsive or mobile site would perhaps be a different CSS file to make the eidogo buttons bigger based on user agent?

That does not make sense. There is one additional black stone but three extra white stones. Where did the other two black moves go?
Still officially AGA 5d but I play so irregularly these days that I am probably only 3d or 4d over the board (but hopefully still 5d in terms of knowledge, theory and the ability to contribute).

I want to say someone on the boards hacked together an eidogo with more mobile friendly buttons.
