Kata Yagura is rarely seen in Kakukawari games . The gold & king are slided together by 1 square right . It prevents an opponent's drop of a Bishop at 5h , 6i (or 5b ,4a) square .
But this idea gives a weak point in 8th (or 2nd) file in the same time .
Kata Yagura is sometimes called "AMANO Yagura" , named after "AMANO Souho" , one of the strongest Shogi Players in Edo era .
