Why did the Bridge visit the counselor? It needed arch support.<\/p>\n

In this week\u2019s position, white wins by constructing a bridge that allows its pawn to cross the board to its promotion square. With this hint in mind, please try to find white\u2019s winning blueprint.<\/p>\n

As long as black can prevent the successful promotion of the white pawn, the game is a draw. Here, black\u2019s rook and king keep the white king from coming out from behind the pawn and opening up the promotion square.<\/p>\n

White\u2019s best move is to check black from f1. Black\u2019s best move is not<\/em> to move closer to the white pawn with king to e6. White\u2019s king then steps over to e8, threatening an immediate promotion, as black\u2019s king shields white\u2019s king from check. Black threatens the pawn with rook to d2, but white\u2019s rook check from e1 pushes the black king away, and white\u2019s pawn promotes (see next diagram).<\/p>\n

\"\"<\/figure>\n<\/p>

After the check from f1, black\u2019s king otherwise retreats to g7 or g6. Either way, white\u2019s best reply is rook to f4. Now if the black rook remains on the \u201cc\u201d file to keep the white king off the \u201cc\u201d file with rook to c3, white\u2019s king moves to e7. Black\u2019s rook checks from e3 and white\u2019s king moves to d6. The black rook checks from d3, and white\u2019s king steps over to e6 and still defends the pawn. Black again checks from e3 and white\u2019s king advances to d5 (see next diagram).<\/p>\n

\"\"<\/figure>\n<\/p>

Black checks once again from d3, this time threatening to skewer white\u2019s pawn. White\u2019s rook, however, intercedes by moving to d4 (the point of the rook lift to f4). White has constructed a bridge that now allows its pawn to cross all the way to the other side of the board and promote.<\/p>\n

Returning to the position after rook to f1, check, black king to g6, and white rook lift to f4, black may opt to move its rook to a2 instead of keeping it on the \u201cc\u201d file. White then moves its king to c7 and black\u2019s rook checks from a7. White\u2019s king, for example, moves to d6 followed by black, stopping the pawn with rook to a8 (see next diagram).<\/p>\n

\"\"<\/figure>\n<\/p>

The white king next moves to e7. Black pins the pawn with rook to a7 but the white king moves to e8, ready to escort its pawn home.<\/p>\n

The oldest bridge still in use is in Greece and dates to 1300 B.C. The bridge constructed in this week\u2019s position dates to 1500 A.D. and is still widely used today.<\/p>\n
