TE[1]C[Correct answer
Black must play 1, because the corner stone is the more valuable one.

C[…White cuts off the black stone with 2 and 4, but Black replies by weakening the white stone with 5 and 7. Black has nothing to complain about.]

C[…White can also answer the block at 3 by cutting at 4. Black profits with 5, and White’s shape leaves much to be desired.]

BM[1]C[Wrong answer
The connection at 1 is the wrong choice.
