An approach can have different meanings
- In general it means a move played in the vicinity of a position, as in Black approaches the white framework. In Japanese it translates to tsume.
- More typical is the move played in the opening, named Corner approach, also known as kakari.
- Moves that are needed at the start of a semeai (so count as extra liberties for the underdog) are called approach moves
- We can also speak about a player's approach to the game, his manner of treating it, or his behaviour to it.
This move is a Tsume definitely, and it also exposes a weakness, so it may be called a kakari (maybe elaborate on Japanese terms on a separate page)
