Occurred in my last game. White resigned instead of playing the circled move. In the game I thought the white move would save the group. Not sure if my opponent read it out, or didn't even think of the move. Relatively easy if you look at it as a tsumego, but I think I might have missed it ingame.

Black connects two above . If white captures, black atari the two stones to the right a bit.
By the way, this doesn't seem to be a good way to post problems as there is no easy way for me to get at the board position to post moves.

white is less dead than possible.

I could only think of this, not sure why I never considered trying my third move as a first move. It still dies, but white gets away slightly.
