All you need to know about Carpenter's Square - 17
Black corner is under more pressure. How can white make good use of *ws*?
Unlike Diagram 16.2, because of *ws*, black has to play *b4*, leaving the key point to white. After the situation is so-called 'Golden Chicken Standing on One Leg' and black is dead.
Trying to emulate Diagram 16.7, black plays *b2*. However, because of *ws*, is possible now. There is simply not enough eyespace in the corner. Black is dead too.
We've mentioned earlier that does not work. White can follow the sequence in Diagram 16.9 and play directly to kill. Or even simpler white can play here. is a good move, creating miai points 'a' and 'b'. Black can not survive.
Conclusion: this is one of the simplest shapes we've covered so far. Black has no chance.
