;B[df];W[dg];B[de];W[ch];B[gc]C[There is something strange with this move - the normal joseki is one space to the right (H17), then W F13 and B F16. Now counterattacking by getting out seems easier for white, as blacks close up pincer can become weak. But I am not sure about this.];W[fd];B[ff];W[gd];B[hc];W[hd];B[dc]C[probably dangerous - see var 2]
(;W[eb]LB[db:a][cb:b][fb:c]C[Honte, but to slow. If white does not like var 2 then maybe the variation a-c could be considered - there still remains a peep at B17 and black cannot play J16 now because the cut J17 works.];B[id];W[hf];B[eg]C[Now blacks aggressive strategy seems to have succeeded - because of move 18. ];W[di];B[ie];W[gf];B[gg]LB[fi:a]C[looks like bad shape but it is difficult where to play - perhaps F11 would be a good alternative - but I am just guessing.]
