This is a problem I invented based upon what might happen if black didn't defend his three cutting stones in the Taisha.

If you think white can capture black by playing at A, play there. Otherwise, play B.]

(;W[sa]C[ - Because of white's defects at A and B, it is very hard (maybe impossible) for white to simply net black. See 'Navigate Solution' for a couple of ways for black to break out. I'm not saying white can tenuki, becaues white can start a good attack on the three black stones, it's just that they are hard to capture directly.RIGHT]
