Sugai played a very strange move on his last game, after exchanging bishops on 3c and with his gold on this square he played rook 3b! This is a new move that has never been seen in professional games. On this position is normal to play Rook 2b.
After this, he used the gold and the rook pressure on the third column and a decisive attack against Habu’s king.
