So six piece handicap means she played 六枚落ち roku-mai ochi - meaning she was without rook, bishop, both lances, both knights
So basically if he lost then it was pretty sad (although handicaps go all the way to ten piece handicaps, loosing rook, bishop, both lances, both knights, both silvers, both golds - and even to the showoff ones of "king only", either with three pawns on hand, or even without pawns.. although in the last case I feel the game will probably be about how long can the king survive)
Going up to four piece handicap 四枚落ち yon-mai ochi - gives her back the knights.
