!!! To demonstrate which resources Black has available in this variation, this sub-variation illustrates what happens if Black has lost an additional liberty earlier. !!!

Please assume that is this liberty-losing move. Then, White will be able to capture Black's top right group (with here), but now Black will close the upper left corner (with here).

Result: Black gets the centre (), and the entire left side (, because he can sacrifice the five -stones, in a similar way to our solution, in a nakade-shape) and wins easily.
