R14 in this one are technically incorrect (although they are the right
moves, of course).

In both cases black can push through and cut on S15 and S15,
respectively. Of course this is bad as white can take the ponnuki, but
if white insists on defending the 3-3 invasion stone, he can only get a
ko.

I would suggest a restricted_genmove C16 C15 test for the first
position. Not sure about the 2nd (S15 is another move to make life,
btw).
