3-4 point approach from the wrong direction
However, when is already on the board (a common situation, which occurs in the Chinese fuseki and the small Chinese fuseki), things are different: A kakari 'from the right direction' is now pincered automatically, giving black an advantage in this corner. Because of this, a kakari like now becomes an alternative. Black making a corner enclosure may now be overconcentrated.
A 'kakari from the wrong direction' against a stone on the 5-3 point is rare; against a stone on the 5-4 point it sometimes does happen, and in this diagram is most common. The reason for this difference is that here does look into the corner, while if the black stone were at a, it would be completely closed away from it.
