[{B:R7/P7/5k2/8/2K5/16/r7 BLACK}{A:Bf6g7}{D:1000}{R}{S:f6g7}
1... Kg7! With this move Black avoids checks and sly tactics. Meanwhile, White can make no progress. If he tries to free his Rook by eventually placing his King at b6, Black's Rook checks and checks and checks. The game is drawn.]

[{B:16/4R3/5r2/3b4/3k4/8/3K4 BLACK}
{A:Bd4e5}{D:1000}{R}{S:d4e5}1... Be5 This creates an e-file obstruction while threatening mate at f1. If 2. Kc1, it's still mate by 2... Rf1#. Meanwhile, 2. Ke1 fails to 2... Bc3+ 3. Kd1 Rf1+ 4. Re1 Rxe1#.]

[{B:r7/2K1P1k1/40/5R2}{A:Wf1a1}{D:1000}{R}{S:f1a1}1. Ra1! Black was threatening to check at a7, with a draw in hand, and this sacrificial offer stops it. If Black takes the Rook (1... Rxa1) White makes a new Queen. The ending from that point can be tough, but the Queen should beat the Rook.]

Question 3 (cont). If Black moves to 1... Re8 instead, what is White's response? Click "Next" for the answer.]

8.
[{B:4r3/2K1P1k1/40/R7}
{A:Wc7d7}{D:1000}{R}{S:c7d7}1... Re8 (or 1... Rh8 2. Kd7 Kf7 3. Rf1+) 2. Kd7 Kf7 3. Rf1+, and White wins.]

Question 4 of 7. What is White's best move? Click "Next" for the answer.]

10.
[{B:8/2P5/8/K7/7R/k7/2r4p/8}{A:Wh4h3}{D:1000}{R}{S:h4h3}1. Rh3+! Here's the move that brings down the walls of Troy. After 1... Kb2 (or 1... Ka2) White wins with 2. Rxh2. Black now has nothing better than to take White's Rook, 2... Rxh2, and the pawn queens, 3. c8/Q. True, winning from here requires technique, but this is not our concern.]

[{B:3r4/7p/Rp4k1/5p2/4p3/2P5/PP3P1P/5K2 BLACK}
Question 5 of 7. What is Black's best move? Click "Next" for the answer.]

[{B:3r4/7p/Rp4k1/5p2/4p3/2P5/PP3P1P/5K2 BLACK}{A:Bd8d2}{D:1000}{R}{S:d8d2}
1... Rd2! This abandons the b-pawn with check! It is, however, the only real way to get counterplay. With his Rook aggressively occupying the seventh rank, Black can now hold the position. A game between Tarrasch and Rubinstein now concluded... 2. Rxb6+ Kg5 3. Ke1 Rc2 4. Rb5 Kg4 5. h3+ Kxh3 6. Rxf5 Rxb2 7. Rf4 Rxa2 8. Rxe4 h5 9. c4 Kg2 10. Rf4 Rc2 11. Rh4 Kf3 12. Kd1 Rxf2 13. c5 Ke3 14. Rxh5 Kd4, and the players agreed to a draw. It took courage to let the b-pawn go, but a passive Rook usually leads to chessic death.]

Question 6 of 7. What is White's best move? Click "Next" for the answer.]

14.
[{B:4k3/5R2/7R/q7/2K5/24}
{A:Wf7a7}{D:1000}{R}{S:f7a7}
1. Ra7! A surprising rejoinder that menaces the Queen and mate at h8, while thwarting safe Queen checks. If Black takes the Rook, 1... Qxa7, he loses to 2. Rh8+ Kf7 3. Rh7. Black's King and Queen are skewered.]

15.
[{B:4k3/R7/7R/q7/2K5/24}
{S:a5e5}
Question 6 (cont). Of course Black doesn't have to play 1... Qxa7. Instead he could play 1... Qe5, guarding h8. How would White respond? Click "Next" for the answer.]

16.
[{B:4k3/R7/7R/4q3/2K5/24}
{A:Wh6h8}{D:1000}{R}{S:h6h8}
2. Rh8+! Qxh8 3. Ra8+ another skewer, this time coming from the other direction. White wins the Queen, leaving himself a Rook ahead.]

18.
[{B:8/4K3/8/3pk3/3R4/24}{A:Wd4d2}{D:1000}{R}{S:d4d2}1. Rd2! This wins because it avoids the loss of a tempo at the key moment.]

[{B:8/4K3/8/4k3/3p4/8/3R4/8}
Question 7 (cont). What is White's response to 1... d4? Click "Next" for the answer.]

[{B:8/4K3/8/4k3/3p4/8/3R4/8}{A:Wd2d1}{D:1000}{R}{S:d2d1}
2. Rd1. This leads to the win of the pawn. If 2... Kd5, then 3. Kd7 Ke4 (or 3... Kc4 4. Ke6) 4. Kc6 Ke3 5. Kc5 d3 6. Kc4 d2 7. Kc3. Note that if White's Rook were on d2 when Black plays Ke3, White would have to forfeit a move to save the Rook, and his King wouldn't get back in time to overtake the pawn. The game would then be drawn.]
