The shape. The Right Silver-46 Rapid Attack after 47 moves of the main line, with the key squares ringed. Black is at the bottom, both sides’ moves are shown, and the pieces in hand are drawn above and below the board.

The idea

The Right Silver-46 is the Boat rapid attack that uses the right silver instead of the left. Black castles in the Boat with the king on 7h, then walks the right silver 4h, 5g, 4f, aiming at White’s bishop on 3c with the pawn break to 3e.

The left silver stays on 7i, so Black’s king is better covered than in the Left Silver-46, and the attack comes two moves sooner; the cost is a thinner right side.

The silver goes to 4f only against White’s silver on 4c. ja.wikipedia traces the attack on 3c with silver, knight and rook to a book from 1804, and says Tsukada Yasuaki made the modern form his weapon from 1984; it returned later against the Fujii System. Both sides’ moves have one source; ja.wikipedia draws the position at move 23.

How it goes together

Both sides’ moves are shown, because this opening is an agreement rather than a system: one player cannot reach it alone, so a one-sided list of moves would be a fiction.

The plan once you are set up

  • Build the Boat: king to 7h, right gold to 5h, and the edge pawn against White’s.
  • When White’s silver goes to 4c, push the pawns to 3f and 2e, and bring the right silver to 5g and 4f.
  • Break with the pawn to 3e. If White swings the rook to 3b and takes back on 3d, drop the pawn again on 3e.
  • Pull the silver back to 3g and bring it in again through 3f, with the rook behind it.
  • Against White’s counter on the 3rd file, trade on 4d and 3e and promote the bishop on 1a.

What to watch for

  • White’s silver on 3b. The right silver to 4f only works against a silver on 4c; against a silver on 3b, aim for the knight to 3g and the rook to 2f instead.
  • The thin right side. After the pawn to 3e, White’s rook to 3b, the pawn to 3d and the silver taking it, do not swing the rook to 3h at once; the source holds the file with a pawn dropped on 3e first.
  • White’s pawn to 4e. It hits the silver on 4f and opens White’s bishop.
  • The Fujii System. Against a king that has not castled, the same silver attack is played early, and the details differ.

What it is played against

A Fourth File Rook with a Mino and the silver on 4c. White’s usual reply is the gold to 5b and the rook to 3b; the source also shows the pawn to 5d, the gold to 3b, and the bishop retreat to 4b followed by a pawn on 3d.

The Fujii System player keeps the king on 6b and pushes the edge pawn, which this attack was later used to punish.

Play it against the bot.

The bot’s search levels, 9 to 12, open from a book that holds two of these openings, the Fourth File Rook and the Yagura; the Mino levels play the openings people play. Either way the review afterwards shows you where the game left the line. Try the line, then try the plan.
