Regarding this fuseki, called the orthodox fuseki on Sensei's library. I was always told that a is correct, but it seems more pros are choosing to play b now. See e.g. the GoGameGuru Commentary here: http://gogameguru.com/commentary-hane-naoki-yamashita-keigo-66th-honinbo/ In particular, it seems Yamashita played this way in game 3 as well. Is this just a new fad, or has some pro analysis found the older way to be wrong? |

I've seen various commentaries that say it's the new way, but no one claiming that the old has been refuted. I suspect it's a case of trying a new thing out to see if it works, but I don't know for sure. |

Yes, A is generally considered better these days. But the history and reasons for this are deep. To summarize, Black found this position to be very comfortable: Up to 5, Black has a good moyo and will press down on White's right group to enlarge it or attack a deep White stone. 6 & 7 are a standard followup. If Black 3 @ A, then White 6 @ B. This is the other usual way to play. Black can also choose A. Partly because of this, W1 became more popular since 2007. So it's not really 'new'. Because of W1, Black had a chance to update his two-space pincer josekies of A and B. This is largely why many new 4-4 josekies have appeared in recent years. The aim of this distance is to extend from the bottom enclosure and still pressure White. Black C is also popular. |

Where did you find this move?It's been played in quite a few pro games. Here's Cho Hyeyeon's comments about this opening: http://loveku.livejournal.com/44746.html Cool shortcodes for the stones by the way. I'd never noticed you could do that    - now that I look, they were sitting right there the whole time

OK, I take back my words  The move still looks really odd to me though... Apparently my intuition needs work

I don't think the wedge has died completely. Here's Park Yeonghun winning with it in 2010: It's worth noting that black doesn't choose the response outlined above in this game, approahing instead from the enclosure side. Actually black gets some very scary thickness early this game, but white does an amazing job reducing it. Here's another from the 2009 Kisei league: In that one it's a bit different, because white went for the 3-4 points. I'm not sure how that changes the analysis. |

The game was against his master, whose name I can't spell correctly, sorry.He concludes by saying "this move ( ) shouldn't be seen so much in the future pro games".
