C[In the actual (5 stone handicap) game, Black understandably plays solidly by capturing the 2 stones.  But this capture is a little soft.];

    C[This joseki sequence is OK, but doesn't fit as well as the game line with Black's center right stones.];

    C[White's bottom position is better than the game line.]

    C[On the other hand, Black cannot take time to defend the corner either.];
    W[oj]
    C[White's connection here is too big, because White captures the 3 key center cutting stones.  The following capturing sequences are instructive for kyu players.]

    C[... Black pursues the center group on a large scale.  And fairly soon, Black will be harassing the right side group.]
