Coach Answer Key — The Rook
These answers emphasize the strategic idea first and use short variations only to validate the plan.
Exercise 1
Best move: 1 Qd2!
Short plan: Keep the f1-rook on its useful square and prepare Rae1, bringing the a1-rook to the open e-file.
Critical line: 1 Qd2 b5 2 Rae1
Strategic theme: Improve the worst rook; prepare occupation of an open file without displacing the active rook.
Tempting alternative / coaching comparison: 1 Rfe1?! is less logical: the f1-rook is already well placed, so moving it solves the wrong piece problem.
Difficulty: 1/5
Source mapping: Original Position 41; S.Kristjansson-I.Sokolov, European Club Cup, Kemer 2007; exercise printed page 307 / PDF page 308; solution printed page 378 / PDF page 379.
Exercise 2
Best move: 1...Rd7!
Short plan: Prepare to double rooks on the d-file before White finishes contesting it.
Critical line: 1...Rd7 2 Rad1 Rfd8
Strategic theme: Doubling rooks on the only open file; tempo in the fight for a file.
Tempting alternative / coaching comparison: The source does not single out a specific first-move alternative. The practical error is delay: White is ready to contest the d-file, so Black must organize the rooks first.
Difficulty: 1/5
Source mapping: Original Position 43; V.Menchik-J.R.Capablanca, Hastings 1930/31; exercise printed page 308 / PDF page 309; solution printed page 378 / PDF page 379.
Exercise 3
Best move: 1 Ra3!
Short plan: Use the third rank to bring the rook toward c3, allowing the major pieces to be tripled on the c-file.
Critical line: 1 Ra3 Rc7 2 Rc3 Qe7 3 Bf1!
Strategic theme: Tripling major pieces on an open file; lateral rook transfer.
Tempting alternative / coaching comparison: The source does not name a first-move alternative. The key move-order point is that direct pressure on c-file targets is weaker until the a-rook reaches c3.
Difficulty: 2/5
Source mapping: Original Position 45; M.Taimanov-G.Lisitsin, Leningrad 1949; exercise printed page 308 / PDF page 309; solution printed page 379 / PDF page 380.
Exercise 4
Best move: 1 Re3!
Short plan: Lift the rook so it can support Qh3 and later swing to d3 to increase pressure on d6.
Critical line: 1 Re3 Ne7 2 Qh3 Ng8 3 Rg3
Strategic theme: Multipurpose rook lift: attacking route plus pressure on a fixed pawn.
Tempting alternative / coaching comparison: No explicit first-move alternative is analyzed. A one-purpose move is less flexible than Re3 because the rook needs access to both the third rank and the d-file.
Difficulty: 2/5
Source mapping: Original Position 47; V.Potkin-Y.Kolotilin, Russian Team Championship 2003; exercise printed page 308 / PDF page 309; solution printed page 379 / PDF page 380.
Exercise 5
Best move: 1...Ra6!
Short plan: Prepare ...Rga8 to double on the a-file before the pawn exchange ...a5xb4 opens it.
Critical line: 1...Ra6 2 Kf2 Rga8 3 Ng1 b5
Strategic theme: Potentially open file: pre-position the rooks before the pawn break.
Tempting alternative / coaching comparison: 1...axb4?! 2 axb4 Ra6 3 Nc3 lets White seize the a-file and improves White’s defensive chances.
Difficulty: 3/5
Source mapping: Original Position 49; G.Gamrekeil-T.V.Petrosian, Georgian Championship, Tbilisi 1944; exercise printed page 309 / PDF page 310; solution printed page 380 / PDF page 381.
Exercise 6
Best move: 1 Ra3!
Short plan: Head for d3 to fight for the d-file, while retaining the option of using the rook on the kingside.
Critical line: 1 Ra3 Rd8 2 Rad3 Rb8 3 Qg4
Strategic theme: Rook lift with two destinations: central file control and kingside activity.
Tempting alternative / coaching comparison: After 1...Rd8, the tempting 2 Rg3? is premature because 2...Nxe5! exploits a back-rank tactical motif.
Difficulty: 3/5
Source mapping: Original Position 51; J.Timman-F.Vallejo Pons, European Championship, Budva 2009; exercise printed page 309 / PDF page 310; solution printed page 381 / PDF page 382.
Exercise 7
Best move: 1 e4!
Short plan: Clear the e-file so the rook can join the attack against Black’s weakened kingside.
Critical line: 1 e4 Na6 2 exf5 Qxf5 3 cxd6 Nc5 4 Re1!
Strategic theme: Pawn break as rook improvement; clearing a file before occupying it.
Tempting alternative / coaching comparison: A direct rook move leaves the e-file closed. The source emphasizes changing the pawn structure first so the rook’s activity becomes concrete.
Difficulty: 4/5
Source mapping: Original Position 53; E.Hedman-E.Berg, Norrköping 2004; exercise printed page 309 / PDF page 310; solution printed page 381 / PDF page 382.
Exercise 8
Best move: 1 Ra1!
Short plan: Place the c1-rook on a1 first, then play a2-a4 so the rook is already aligned with the file that will open.
Critical line: 1 Ra1 f5 2 a4 Bg5 3 Bxg5 hxg5 4 axb5
Strategic theme: Prepare a file-opening pawn break by placing the rook behind the future file.
Tempting alternative / coaching comparison: The source does not analyze 1 a4 immediately. Its move order shows the principle: improve the rook first, then make the irreversible pawn break.
Difficulty: 4/5
Source mapping: Original Position 55; L.Vogt-J.Franzen, Stary Smokovec 1979; exercise printed page 310 / PDF page 311; solution printed page 382 / PDF page 383.
Exercise 9
Best move: 1...Ra6!
Short plan: Use the sixth rank to support ...Ne4 and then ...Rh6, creating a coordinated kingside attack.
Critical line: 1...Ra6 2 Rc1 Ne4 3 Nxe4 dxe4 4 Ne5 Rh6
Strategic theme: Rook lift across the sixth rank; coordination with a knight and queen attack.
Tempting alternative / coaching comparison: 1...Re6?! is less accurate because 2 g5 gains useful space and interferes with the intended attacking setup.
Difficulty: 5/5
Source mapping: Original Position 57; D.Sharma-V.Baklan, Balaguer 2006; exercise printed page 310 / PDF page 311; solution printed page 382 / PDF page 383.
Exercise 10
Best move: 1 a5!
Short plan: Prevent ...a5 from closing the queenside, then prepare Reb1 and b3-b4 to clear the b-file toward b7.
Critical line: 1 a5 f6 2 Reb1 fxg5 3 b4!
Strategic theme: Potentially open file; prophylactic move order before a rook-file plan.
Tempting alternative / coaching comparison: 1 Rab1? fails to 1...a5!, closing the queenside. The immediate 1 Rh1+?! also fails to advance the real plan.
Difficulty: 5/5
Source mapping: Original Position 60; A.Karpov-B.Spassky, Candidates match (game 3), Leningrad 1974; exercise printed page 310 / PDF page 311; solution printed page 383 / PDF page 384.
