Solutions
Exercise 1
Best move: 1...Be8!
Short plan: Reroute the d7-bishop to g6, where it controls the b1-h7 diagonal and becomes a stable active piece.
Critical line: 1...Be8 2 Bg4 Qb6+ 3 Kh1 Bg6 4 Qb1 Qc6
Strategic theme: Bishop rerouting to an ideal diagonal
Why the tempting alternative is inferior: A routine rook or queen move leaves the bishop passive and fails to improve Black’s worst-placed piece.
Difficulty: 2/5.

Exercise 2
Best move: 1 c4!
Short plan: Clear the g2-a8 diagonal so the bishop has no effective counterpart and can influence both wings.
Critical line: 1 c4 Nc7 2 Qc2 Qe7 3 Be4 h6 4 Bb2
Strategic theme: Clearing a long diagonal with a pawn move
Why the tempting alternative is inferior: A direct bishop development leaves the c-pawn blocking the diagonal and misses the strongest structural improvement.
Difficulty: 2/5.

Exercise 3
Best move: 1 Qf2!
Short plan: Prepare Bd4 under tactically favourable conditions, then use the bishop and queen to build kingside pressure.
Critical line: 1 Qf2 Nc3 2 Kb1 Na4 3 Bd4 Qf8 4 Nd3
Strategic theme: Preparatory move before bishop centralization
Why the tempting alternative is inferior: The immediate bishop move is premature because Black has a queen capture and knight-fork resource.
Difficulty: 3/5.

Exercise 4
Best move: 1 a3!
Short plan: Prepare b3-b4 and Bb3+, opening and occupying the a2-g8 diagonal while fixing Black’s queenside.
Critical line: 1 a3 g6 2 Qf3 h5 3 b4 Bb6 4 Bb3+ Kg7
Strategic theme: Creating a bishop route with a pawn lever
Why the tempting alternative is inferior: Playing b4 immediately is insufficiently prepared and gives Black more tactical and structural counterplay.
Difficulty: 3/5.
Source mapping: original position 5; J. Hellsten-B. Sahl, Arlov 1995; printed page 301, PDF page 302; solution printed page 368, PDF page 369.
Exercise 5
Best move: 1...d5!
Short plan: Sacrifice a pawn to clear the a1-h8 diagonal. Black gains an active bishop and a dangerous passed e-pawn.
Critical line: 1...d5 2 Nxd5 Bxd5 3 exd5 Rxc2 4 b3 e4
Strategic theme: Dynamic pawn sacrifice to release the bishop
Why the tempting alternative is inferior: A quiet improving move keeps the bishop shut and gives White time to consolidate the extra space.
Difficulty: 3/5.

Exercise 6
Best move: 1...b4!
Short plan: Offer a pawn to establish the bishop on a4 and then c2, creating direct pressure and tactical threats.
Critical line: 1...b4 2 axb4 Ba4 3 Ra1 Bc2 4 Bg3 Be4+
Strategic theme: Pawn offer for bishop entry squares
Why the tempting alternative is inferior: 1...Rf8 is sensible but slower; it allows White time to coordinate, while ...b4 creates immediate forcing access.
Difficulty: 4/5.

Exercise 7
Best move: 1 a4!
Short plan: Create the square a3 for the bishop, activate the bishop pair, and prepare a central passed-pawn advance.
Critical line: 1 a4 Nc7 2 Ba3 Rxb1 3 Rxb1 Re8 4 Ne3
Strategic theme: Pawn preparation for bishop activation
Why the tempting alternative is inferior: A knight move alone does not solve the inactive bishop; the a-pawn move changes the geometry of the queenside.
Difficulty: 3/5.
Source mapping: original position 10; S. Bjarnason-J. Hellsten, Malmo 1991; printed page 302, PDF page 303; solution printed page 369, PDF page 370.
Exercise 8
Best move: 1 Bf1!
Short plan: Transfer the bishop to g2, where it attacks the queenside along the long diagonal and supports pressure on weak pawns.
Critical line: 1 Bf1 Rac8 2 Bg2 Bb4 3 Ne2 Rc7 4 Kf1
Strategic theme: Retreat and redeployment to a better diagonal
Why the tempting alternative is inferior: 1 Bb2 is less incisive because Black can occupy the open files and neutralize the bishop before it gains useful targets.
Difficulty: 3/5.

Exercise 9
Best move: 1 Bd2!
Short plan: Use Bd2-e1-g3 to improve the bishop, reinforce the king, and keep the option of switching pressure to the queenside.
Critical line: 1 Bd2 Kh8 2 Be1 Qa8 3 Bb5 Qb6 4 a4
Strategic theme: Multi-purpose bishop manoeuvre
Why the tempting alternative is inferior: A direct queenside deployment is less flexible and does not address the kingside defensive task.
Difficulty: 4/5.
Source mapping: original position 14; G. Giorgadze-K. Lerner, Lvov 1990; printed page 303, PDF page 304; solution printed page 370, PDF page 371.
Exercise 10
Best move: 1 b4!
Short plan: Prepare b4-b5 to soften the long diagonal for the g2-bishop and gain activity before Black stabilizes.
Critical line: 1 b4 Bxc4 2 b5 cxb5 3 Nxb5 Rd8 4 Ba3
Strategic theme: Queenside pawn break to open a fianchetto bishop
Why the tempting alternative is inferior: A quiet piece move leaves the diagonal closed and gives Black time to complete coordination.
Difficulty: 4/5.
