Post subject:  superclass tsumego

we're starting off with a superclass tsumego series, about 2 sets a month we will try to give ranging from 4d to 7d in level of hardness. this thread is to discuss the tsumego since we will not give the answers. Studying this way is harder but more effective. Thanks to adoreme who helps us select these tsumego.

Top right problem:
I haven't found a way for b to live, after white plays n15.
Some sequences:
W n15, B o15, W n14, B n16, W p17, B p16, W o16 (dead)
W n15, B p17, W n16, B n14, W p13 (dead)
W n15, B n16, W o15 (dead)
W n15, B n14, W o15 (dead)
W n15, B o16, W p17 (dead)

If anyone sees how should B respond to live, pm me :P.
