Life on the second and third lines series #2. Play to get a chance of life, or play T for tenuki if white is unconditionally dead. Other problem(s) in the series: 22639, 22803, 22829, 22339. Sorry for the lack of incorrect variations earlier; I have added some more. If you turn on "public attempts" in your user settings, I can see which variations you played, and know which ones to add.
