For reference, the same pincer against the high approach move has also become prevalent recently. It does not have quite the pedigree of the previous pincer - only 450 examples and rather fewer ways for White to answer. It also did not really enter the repertoire in open-field play until the 1960s, although there was an example by Go Seigen in 1954 in a three-stone handicap game.
This opening has been called the Magic Dirk, by analogy with the wider pincer the Magic Sword. As far as we know, the name is due to David Mitchell, a British 4-dan now in Australia.
The bloodthirsty name seems apposite for a Korean fuseki. Strangely, though, despite the fact that it is quite common now, most Koreans seem to avoid it. It is popular with both Chinese and Japanese players. The pincer against the low approach is the one to concentrate on here.
