White sacrifices a stone at 1, and then proceeds making two eyes by capturing 2 and 4, sacrificing the marked stones.
At several stages, White can make a mistake.
It's tempting to protect the marked stones, but Black 2 makes it ko. If White connects at a, Black b kills unconditionally.
This exemplifies the proverb "Get strong at Gote". White dies in gote, the worst of all events, because Black can almost fill White's eyespace with a bulky five at any time.
Simply connecting is not good enough. After Black 4, Black will be able to almost fill White's eyespace with a killing shape.
Maybe this 1 is a candidate that comes to mind. Black grabs the vital point at 2. If , then
blocks on the outside. If White plays at a to prevent the snapback, he dies in gote.
