At Play Go at online-go.com! | OGS, OGS Joseki says that the position is settled.
A month or so ago, though, a new-ranks 4d player advised me that Black should take the R13 atari immediately, a recommendation I just remembered whilst reviewing a sanrensei game.
What do you think of this? I can see that it removes a white point in sente, makes a potential point for Black, and removes the possibility of S14 being a white eye, a fact that might be relevant in certain obscure ko situations. And it won’t be sente after Black fixes the cut with O13.
Also, regardless of whether Black makes that atari, it should be noted on the position that Black very often does play the O13 fix. In fact, it’s questionable whether the position can really be called settled with the P13 cut still on the board.
