Approach

An approach can have different meanings

1. 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.
2. More typical is the move played in the opening, named Corner approach, also known as kakari.
3. Moves that are needed at the start of a semeai (so count as extra liberties for the underdog) are called approach moves
4. We can also speak about a player's approach to the game, his manner of treating it, or his behaviour to it.
