is a good exchange for Black since it prevents White from pressing Black down as in the joseki]W[nn]

;C[The triangled stones are, as we say in German, 'krass geschnitten',
i.e. cut while Black is solidly connected. Normally, when you cut a keima, the cutting stones are also
cut, this is why this shape is too bad for White. I was looking for an English translatation for the
'krass geschnittenes Keima' j8-l9, and I came up with 'Fiercely Cut Keima', or short 'F*CK'. This is
what it should feel like for White. 'F*CKs' are usually much worse shape than empty triangles]B[ik]CR[jl][kl][jk]TR[kk][il]

;LB[jh:B][ji:A]C[Why? You lose other sente moves, such as m10 or n11 or maybe o10, if you might
need them. And you lose a liberty at m10. For instance, after the exchange, it is harder to answer
a white move at 'A' with the hane at 'B'.]B[mk]
