C[The game move.  Black incorrectly seems to think that connecting safely with the lower center group is necessary.  However, this move is not only on dame, but also unnecessary.  Even if Black does not play around here, the reader can verify that White cannot cut off the lower center group.];

C[Again, Black unnecessarily connects.  Black has not read out the safety of the lower center group.  Black can do much better than this sequence.]

    C[Knowing that White cannot cut off the group, Black might push here to attack White's entire lower left group.  But Black has an even simpler strong approach.]

    C[Finally, Black takes a firm grip on the marked stone.

The enormous difference between this position and the main line (from the actual game) should be obvious.]
