;Comment[A very flexible move.
Jiang Zhujiu said that the reason he played here was because most dan level players know this Joseki, and so he played this move to make it more interesting for black. chuckle :-\)]
White[hp]
;Comment[I prefer J3 because it can get territory right away. Later, if white enters 3-3, black can play at C4. If white plays E4, black can play at D3
to get corner. If white plays at D3, Black C3 should be good enough. Anyway, black will become more flexible around the corner.]

more liberty.
Jiang Zhujiu said the same thing.]

;Comment[White made a severe mistake for this. White should play at L6 or around K13. The three pieces are not big at all. After black discards the three pieces, white has a real
hard time. You will see why white plays very strongly later.
Jiang Zhujiu disagrees. He played here because a black move at N2 would reduce white's territory too much.]
