Broken ladders

Examples of professional play

Almost an example of a ladder ko (as ko is only very near, but not affecting the ladder liberties itself) played by professionals, but most of all, the ladder is not working: [ext] broken ladder ex. 1 provided by Go4Go.net?.
I don't understand this part of the game. tderz

There is another example of a broken ladder between Feng Yun 9p and JZJ, 9p: broken ladder ex.2
I think to recall that Feng had Black and JZJ a moyo which Feng entered, where by a cutting stone was apparently controlled in a ladder.

Feng won the game because that ladder was broken and so JZJ's strategy.
However the most interesting point for me was, that Feng seemingly waited some moves before pulling out that stone (played some moves into the corner first, as she was seeking for live on the edge). I guess that was for maximising the dammage.
I sent her once an e-mail with that question, but of course Feng is very busy. I wrote already something here here on SL regarding that game. tderz
