Diagram 33.1: White to play
This is yet another 'incomplete' Carpenter's Square.
Diagram 33.2: Benchmark
We again use the standard Carpenter's Square as a benchmark. Can white can anything better than a direct ko?
Diagram 33.3: Variation
can also play this a very flexible shape to form a ko.
Diagram 33.4: Solution
then 
is the correct combination. After 
, 'a' and 'b' are miai points so the corner is dead.
Diagram 33.5: Variation
doesn't work either. After the corner is dead too due to short of eyespace.
Conclusion: this 'incomplete' Carpenter's Square can be killed. Diagram 33.4 is the only correct way.
