The opening gets its name from White omitting their defensive left gold development (…G-32) and instead opting for an early bishop trade in order to initiate a quick attack line with their bishop in hand. The missing defensive gold leaves White lacking a ‘guard.’The opening is considered speculative since it is thought to favor Black and is not used by professional shogi players. However, it is tactical and quickly enters the endgame consequently being challenging to defend against successfully by some amateur players.Development[edit]Double Wing with Open Bishop Diagonals\u2616 pieces in hand: \u2013987654321\u00a0\u9999\u6842\u9280\u91d1\u738b\u91d1\u9280\u6842\u99991\u00a0\u98db\u00a0\u00a0\u00a0\u00a0\u00a0\u89d2\u00a02\u6b69\u00a0\u6b69\u6b69\u6b69\u6b69\u00a0\u6b69\u6b693\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u6b69\u00a0\u00a04\u00a0\u6b69\u00a0\u00a0\u00a0\u00a0\u00a0\u6b69\u00a05\u00a0\u00a0\u6b69\u00a0\u00a0\u00a0\u00a0\u00a0\u00a06\u6b69\u6b69\u00a0\u6b69\u6b69\u6b69\u6b69\u00a0\u6b697\u00a0\u89d2\u91d1\u00a0\u00a0\u00a0\u00a0\u98db\u00a08\u9999\u6842\u9280\u00a0\u7389\u91d1\u9280\u6842\u99999\u2617 pieces in hand: \u2013This section needs expansion.

The branch of this variation starts after both players advance their rook pawns and open their bishop diagonals.4.G-78. Black plays the defensive move by developing their left gold to the seventh file so that it protects the 87 and 88 squares.The position at this point is Double Wing Attack opening (where both players exchange their rook pawns off the board) with mutually open bishop diagonals (see: Double Wing Attack\u00a7Open bishop diagonal variation), which most commonly develops into a Side Pawn Capture opening after Black takes White’s side pawn.However, these openings progress as usual only when White mirrors Black’s defensive gold move with 4…G-32, which is the joseki move. In contrast, in the No Guard opening, White does not mirror Black’s position and instead initiates a rook pawn trade before Black leaving their left gold on its starting square.No Guard\u2616 pieces in hand: \u2013987654321\u00a0\u9999\u6842\u9280\u91d1\u738b\u91d1\u9280\u6842\u99991\u00a0\u98db\u00a0\u00a0\u00a0\u00a0\u00a0\u89d2\u00a02\u6b69\u00a0\u6b69\u6b69\u6b69\u6b69\u00a0\u6b69\u6b693\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u6b69\u00a0\u00a04\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u6b69\u00a05\u00a0\u6b69\u6b69\u00a0\u00a0\u00a0\u00a0\u00a0\u00a06\u6b69\u6b69\u00a0\u6b69\u6b69\u6b69\u6b69\u00a0\u6b697\u00a0\u89d2\u91d1\u00a0\u00a0\u00a0\u00a0\u98db\u00a08\u9999\u6842\u9280\u00a0\u7389\u91d1\u9280\u6842\u99999\u2617 pieces in hand: \u20134…P-86No Guard\u2616 pieces in hand: \u6b69987654321\u00a0\u9999\u6842\u9280\u91d1\u738b\u91d1\u9280\u6842\u99991\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u89d2\u00a02\u6b69\u6b69\u6b69\u6b69\u6b69\u00a0\u6b69\u6b693\u00a0\u00a0\u00a0\u00a0\u00a0\u6b69\u00a0\u00a04\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u6b69\u00a05\u00a0\u98db\u6b69\u00a0\u00a0\u00a0\u00a0\u00a0\u00a06\u6b69\u00a0\u00a0\u6b69\u6b69\u6b69\u6b69\u00a0\u6b697\u00a0\u89d2\u91d1\u00a0\u00a0\u00a0\u00a0\u98db\u00a08\u9999\u6842\u9280\u00a0\u7389\u91d1\u9280\u6842\u99999\u2617 pieces in hand: \u6b695.Px86 Rx864…P-86 5.Px86 Rx86.

Black follows White in also making the rook pawn exchange. Both players now have two pawns in head each.Black is not required to exchange their rook pawn here. If Black prefers not to play the main No Guard lines, then they can foil White’s plans with 6.P*87, which forces White’s rook to retreat and closes the eighth file to Black’s rook attacks.
