23-B. Queen to her king's bishop's 5th square.-(38)

Checking.

W. King to his queen's knight's square.-(58) 24-B. Rook takes the bishop.-(46 to 44)*

W. Rook retakes the rook.-(60 to 44) 25-B. Queen to her king's bishop's 4th square.(30) W. Queen to her king's 4th square.-(37)† 26-B. Queen takes the queen.-(30 to 37)

W. Knight takes the queen.-(31 to 37) 27-B. Rock to his king's bishop's 5th square.— 38)

W. Knight to his king's knight's 5th square.(31)

Black here takes the white king's bishop, as it is playing upon his king's rook's pawn (16), the capture of which would much embarrass his king, who could not retake, as by so doing he would be in check to the white queen's knight, situate on his king's knight's fifth square (31). It also leaves the black queen at liberty by moving to her king's bishop's fourth square (30), to support her king's rook against the attack of the white queen's rook; at the same time, by the removal of the rook (44) forming a discovered check on the white king.

+ White here wishes to exchange queens, having the advantage of a rook against a bishop, and finding her troublesome. Black is compelled to the exchange, to avoid check-mate, otherwise given thus:

B. Queen retires to her king's third square (21). W. Queen takes the king's rook's pawn (from 37 to 16), giving Check-mate. The black king cannot take the queen, or move to his bishop's second square (14), as he would in either case be in check to the white queen's knight; neither can he move to his rook's square, as he would there be in check to the white queen.

28-B. Queen's bishop's pawn one square.-(35) ·

W. Queen's rook to her king's knight's 3rd square.-(47) 29-B. Knight to his queen's bishop's 4th square.—(27) W. Knight to his king's 6th square.—(21) 30-B. Queen's knight takes the knight.-(27 to 21) W. Pawn retakes the knight.—(28 to 21) 31-B. Rook to his king's bishop's 3rd square,—(22) W. King's rook to his queen's square.-(60) 32-B. Rook takes the pawn.-(22 to 21)

W. King's rook to his queen's 7th square.-(12)* 33-B. Rook to his queen's bishop's 3rd square.—(19) W. Queen's rook takes the pawn.-(47 to 15)—Checking 34-B. King to his bishop's square.-(6)

W. King's rook's pawn one square.-(32) 35-B. King's pawn one square.-(37)

W. Queen's rook takes the pawn.-(15 to 16) 36-B. Bishop to his king's 4th square.-(29)†

W. King's rook to his king's 7th square.-(13) 37-B. Bishop to the queen's 3rd square.-(20)

W. King's rook to his queen's 7th square.—(12) 38-B. King's pawn one square.-(45)

* White must now win the game; Black can only hinder him from doubling his rooks by the sacrifice of his bishop, or allowing White to push his pawn to queen; so that any way he loses the game.

+ Black plays his bishop thus, to command his king's rook's square, and prevent Check-mate by the white queen's rook playing thereto.

* Black plays thus, to intercept White's pawns, which White counteracts by advancing his queen's knight's pawn two squares upon the black queen's knight, forcing Black to take 'en passent.' This re-joins White's pawns and renders them invincible.

+ This move of the white knight determines the game, having now all Black's pieces iu some measure blocked up, until he can prepare Check-mate.
