In shogi, Side Pawn Capture Bishop-33 (横歩取り3三角 or 横歩取り☖3三角 yokofudori san-san kaku) is a set of variations stemming from the Side Pawn Capture opening, in which White first trades pawns on the eighth file and then blocks Black from trading bishops by moving White's bishop to the 33 square. This is the most common variation of the Side Pawn opening.
