I have found a possible problem in this joseki, see josekipedia:
They comment this white's move as "Makes life". But it seems to me that white is dead actually - what about this sequence?
$$c Black kills white? $$ --------- $$ ...3412.- $$ .XXOO5OO- $$ .XOXOOX.- $$ ..OXXX.X- $$ ......X.- $$ ........-
So that T18 move seems like a big mistake. White perhaps should have played R19 instead and go to a ko fight?
So is there a mistake on josekipedia or did I miss something?
