Very large knight's move
The very large knight's move is often a good extension along the side (J: dai-dai-geima-biraki).
The very large knight's move may also be used to approach a corner stone very loosely (J: dai-dai-geima-gakari).
It is not a go term though. Its use in shogi is due only to the fact that the people inventing the large variants were Buddhist priests. Maka is Sanskrit maha = big.
