This choice of is a relatively modern move, which became quite popular in the 1990s. Its aim is to get sente. A black stone at a is more or less required, but in this joseki it is almost always present anyway. White invariably answers at 2. Black 3 next is the proper move; Black b is a bit of an overplay. After this, White can choose between c and d.

If White does play the marked stone, Black will not answer it - if Black does intend to answer it, Black would have done better to play the old variation. White's follow-up will probably be and here. This also shows why the stone is important. Without it, White would play the double hane at rather than , which would not be to Black's liking.
