Howdy!

A couple of life and death problems ...

Problem a: White moves, black dies (5-7 kyu range)

Problem b: Black moves, black lives (relatively easy - 15-20 kyu?)

I found problem "a" while working through Maeda's Life and Death (elementary level), by Maeda Nobuaki. Interesting problem!

Howdy WJE,

Take another look at Problem a (not quite that simple). Your answer for Problem b is correct.

Enjoy!
