4463 enclosure, 2-5 approach
    Keywords: MiddleGame, Joseki

Very low approach to 4463

One way to enter a framework built up around a 4463 enclosure is with W1 on the second line. This gives better chances of unconditional life than the 3-3 invasion, which normally becomes ko. On the other hand: there are some complex variations possible; White may need to apply sabaki techniques; and it is undeniable that White may end up with a low position.

Black's answers

In pro games, four replies from Black are seen: in order of popularity, they are a, b (see 4463 enclosure second-line diagonal attachment), c and d. Naturally, since this is a middlegame joseki, any nearby stones may have a big effect on the choice of direction and subsequent fighting.
