{S:a1c1}
{VB:Question 1 of 7.
How should Black respond to 1. Rc1?;
c8c1;Correct. This direct exchange forces White to take back, 2. Bxc1:3;
Incorrect.{JD:3};
c8c4:Not so bad, but not the best answer. Now if White takes the Knight (2. Bxa5) he hangs his Rook (2... Rxc1+). But trading Rooks (2. Rxc4) should avoid trouble.{JD:3}:1;
c8c6:Not the best answer. So that if the Rook is taken, 2. Rxc6, Black can straighten his pawn structure, 2... bxc6. But White isn't lost here.{JD:3}:1;
a5c4:Incorrect. As a rule it's not a good idea to put your own pieces in pins. White is fine after 2. b3 Nd6 3. Rxc8+ Nxc8.{JD:3}:0;
a5c6:This menaces nothing. Better to play the winning move instead.{JD:3}:0}]

[{M:B}{S:d2c1}
{VB:Question 1 (cont). What is Black's next move?;
a5b3;Correct. The dark-square is trapped.:2;
Incorrect.}]

[{B:r3kb1r/1pp2pp1/p1p2q2/4p1N1/4Pnp1/3PB3/PPPN1PP1/R2Q1RK1 BLACK}
{S:d1g4}
{VB:Question 2 of 7. What should Black play after 1. Qxg4?;
f6g5;Correct. This steals a piece, leaving Black a pawn ahead. White's Queen is overloaded. It can't take Black's Queen, 2. Qxg5, because then the f4-Knight will be able to mate at e2, the square abandoned by White's Queen once it takes on g5.:10;
Incorrect.;
f6h6:This is not the best answer. Black menaces mate along the h-file, but 2. Nh3 closes the line and allows White to keep his extra piece, for 2... Nxh3+ 3. Qxh3 Qxh3 4. gxh3 Rxh3 5. Kg2 dissolves the tension, while handing White a winning game.:1;
h8h5:This is not the best answer. This puts the Rook in a vulnerable spot, and after 2. Bxf4, Black must follow with 2... Qh6. White stops the mate and secures the position by retreating the Knight to h3. With the h-file closed, the case is closed. White should eventually win with his extra material.:1;
f8e7:This is not the best answer. White safeguards his g5-Knight by trading on f4, 2. Bxf4 exf4, and then shifting his Queen-Knight to f3, with control of the position. If the h-file should then become precarious, White can block it by Ng5-h3.:1}]

[{B:8/p5kp/1q3pp1/8/3n2N1/2Q2P1P/P1p3P1/4K3 BLACK}
{S:g4e3}
{VB:Question 3 of 7. How should Black respond to 1. Ne3?;
b6b4;Correct. This pin essentially forces White to capture Black's Queen, for 2. Kd2 is busted by 2... Qxc3+ or even 2... c1/Q+, and Black comes away with an extra Queen. Since this leads to a quick burial for White, he must play 2. Qxb4:10;
Incorrect.{JD:7};
b6b1:This is not the best answer. This looks imposing, but after 2. Kd2, White is still successfully fighting off the wolves.{JD:7}:1;
b6e6:This is not the best answer. Black pins the Knight, but White can move his King out of the pin, say to d2 or to f2, and the walls haven't been breached yet.{JD:7}:1;
b6a5:This is not the best answer. Black tries to disrupt matters with a pin, but with 2. Qxa5, Black merely gets his old Queen back by promoting at c1, and meanwhile he's spent his dangerous pawn. No win in sight here.{JD:7}:1;
d4b5:This is not the best answer. Despite simultaneous threats -- an attack on the Queen and a discovery to the Knight at e3, White stays glued together by 2. Qd2.{JD:7}:1;
c2c1Q:Incorrect. Boldly played, but where does it go? After 2. Qxc1, Black is not in position to justify the sacrifice.{JD:7}:0}]

5.
[{S:c3b4}{M:B}
{VB:Question 3 (cont). What is Black's response to 2. Qxb4?;
c2c1Q;Correct.:0;
Incorrect.{JD:7}}]

6.
[{M:B}{S:e1f2}
{VB:Question 3 (cont). What is Black's response to 3. Kf2?;
c1e3;Correct. Black thereby emerges a Knight ahead, for 4. Kxe3 encounters the fork 4... Nc2+. Black regains the Queen with a winning material superiority.:5;
Incorrect.}]

[{B:3r4/1b1rb1k1/p6p/P2p1P2/1p3p2/1P1B4/2R2B1P/4R1K1}
{S:d5d4}
{VB:Question 4 of 7. How should White respond to 1... d4?;
e1e7;Correct. This annihilating blast ruins Black's dark-squares and completely fractures his game.:10;
Incorrect.{JD:12};
f2d4:This is not the best answer. White apparently pilfers a pawn, but after 2... Rxd4 3. Rxe7+ Kf6 4. Rxb7 Rxd3, Black's pieces are breaking out. They can do damage, too.{JD:12}:1;
e1e6:This is not the best answer. This invasion appears portentous, but after 2... Bf6, White can't take on a6 without incurring risk -- 3. Bxa6 Bxa6 4. Rxa6 d3.{JD:12}:1;
d3c4:This is not the best answer. White seizes a powerful diagonal, but this unblocks the d-pawn. It takes on a certain insidiousness with 2... d3.{JD:12}:1;
f5f6:Incorrect.  This is premature. Black grabs the pawn, 2... Bxf6, and this actually solidifies his position.{JD:12}:0}]

[{S:d7e7}{M:W}
{VB:Question 4 (cont). What is White's response?;
f2h4;Correct.:0;
Incorrect.{JD:12}}]

[{M:W}{S:g7f7}
{VB:Question 4 (cont). How should White respond to 3... Kf7?;
h4e7;Correct.:0;
Incorrect.{JD:12}}]

[{M:W}{S:f7e7}
{VB:Question 4 (cont). How should White respond to 4...Kxe7?;
c2c7;Correct.:0;
Incorrect.{JD:12}}]

11.
[{M:W}{S:d8d7}
{VB:Question 4 (cont). How should White respond to 5...Rd7?;
f5f6;Correct. Black must drop material to stop this pawn. No better is 3... Red7 4. Bxd8 Rxd8 5. Rc7+, forking and gaining the b7-Bishop. Just as bad is 3... Ree8 4. Bxd8 Rxd8 5. Rc7+, and no hope is offered by 3... Rde8 4. f6+, a humiliating pawn fork.:5;
Incorrect.{JD:12}}]

[{B:4r2k/p1p1rbpn/1p1q1p1p/3p1P2/3P1N1P/P3P1R1/1P3QP1/4R1K1}
{S:c7c5}{VB:Question 5 of 7. How does White respond to 1... c5?;
g3g7;Correct. Black's position is undermined.:10;
Incorrect.{JD:14};
f4g6:Incorrect. White's fork comes to nothing after 2... Bxg6, when 3. Rxg6 encounters 3... cxd4.{JD:14}:0;
g3g6:Incorrect. This is mere bluster. White threatens nothing, so Black can crash through by taking on d4.{JD:14}:0;
d4c5:Incorrect. By exchanging on c5 White allows Black to secure his Queen (2... Qxc5), preventing a winning tactic.{JD:14}:0}]

13.
[{M:W}{S:h8g7}
{VB:Question 5 (cont). What is White's response?;
f2g3;Correct. After the natural 2... Kxg7, White wins by 3. Qg3+! Regardless how Black replies, White will be able to move his Knight with check, unveiling a winning discovery to Black's Queen from White's Queen at g3.:5;
Incorrect.}]

[{B:2r4k/2r3pp/1p1p1q2/1P1P4/pKP1b3/P7/3Q3P/2R2BR1 BLACK}
{S:f1h3}
{VB:Question 6 of 7. How should Black reply to 1. Bh3?;
e4c2;Correct. A brilliant move that ignores the apparent threat while causing irreparable interference in White's defensive setup.:10;
Incorrect.{JD:18};
e4d3:This is not the best answer. Not without bite, but White can survive if he flosses. One of the crazier variations is-- 2. Bxc8 Qd4 3. Rg4 Qc5+ 4. Kxa4, and there's no significant decay.{JD:18}:2;
f6a1:This is not the best answer. Don't laugh, or at least not a full guffaw. If White becomes greedy and takes the Queen, 2. Rxa1, Black captures on c4 with mate. In order to defend after 1... Qa1, White should probably eliminate a Rook, 2. Bxc8, reducing the enemy attack force. Then White is ready to take the Queen.{JD:18}:1;
f6f3:Incorrect. Black threatens mate at b3, but 2. Rg3 provides an x-ray defense, and White will soon be able to eat Mr. Rook, Bh3xc8.{JD:18}:0;
e4d5:Incorrect. This fails to 2. Bxc8, lessening the attacker's impetus and preparing to unleash volleys of his own, such as taking the Bishop on d5.{JD:18}:0}]

[{S:d2c2}{M:B}
{VB:Question 6 (cont). How does Black continue?;
c7c4;Correct.:0;
Incorrect.{JD:18}}]

16.
[{M:B}{S:c2c4}
{VB:Question 6 (cont). How should Black respond to 3. Qxc4?;
f6b2;Correct.:0;
Incorrect.{JD:18}}]

17.
[{M:B}{S:b4a4}
{VB:Question 6 (cont). How should Black respond to 4. Kxa4?;
c8a8;Correct. White also collapses after 2. Rxc2 Qb2+! 3. Rxb2 (3. Kxa4 is answered by a mating Rook check on the a-file) 3... Rxc4#. And unless White does something after 1... Bc2!, Black's Queen invades on the unguarded b2-square, delivering instant mate.:10;
Incorrect.{JD:18}}]

18.
[{B:4r1k1/p4ppp/4n1r1/1p1pP3/1Q4bq/3P4/PB3PPP/R3RNK1 BLACK}
{S:h2h3}
{VB:Question 7 of 7. How should Black respond to 1. h3?;
g4f3;Correct.:10;
Incorrect.{JD:-1};
d5d4:This is not the best answer. It breaks the pin along the rank, but White can take the piece, 2. hxg4, and keep it.{JD:-1}:1;
h7h5:This is not the best answer. After 2. hxg4 hxg4 3. Ng3 Rh6 4. Kf1, White escapes with his booty.{JD:-1}:1;
e6g5:This is not the best answer. An interesting try, but doomed to failure after 2. hxg4 Nh3+ 3. gxh3 Qxh3 4. Nh2, with 5. Re3 to follow.{JD:-1}:1;
g4h3:Incorrect. This goes nowhere. In fact it loses to 2. Qxh4 Rxg2+ 3. Kh1, and that's all folks.{JD:-1}:0}]

19.
[{S:b4h4}{M:B}
{VB:Question 7 (cont). White has little choice. His Queen is blowing in the wind, while g2 is attacked with gale force. So he plays 2. Qxh4, and how does Black continue?;
g6g2;Correct.:0;
Incorrect.{JD:-1}}]

20.
[{S:g1h1}{M:B}
{VB:Question 7 (cont). How should Black respond to 3. Kh1?;
g2f2;Correct.:0;
Incorrect.{JD:-1}}]

{VB:Question 7 (cont). How should Black respond to 4. Kg1?;
f2g2;Correct.:0;
Incorrect.{JD:-1}}]

{VB:Question 7 (cont). How should Black respond to 7. Kh1?;
g2g4;Correct.:0;

[{M:B}{S:h1h2}
{VB:Question 7 (cont). How should Black respond to 8. Kh2?;
g4h4;Correct.:0;
Incorrect.{JD:-1}}]

26.
[{M:B}{S:h2g3}
{VB:Question 7 (cont). How should Black respond to 9. Kg3?;
h4f4;Correct. A fantastic illustration of a windmill attack, where Black relies on repeated discoveries to clean out the goodies in White's position. In the end, Black is a piece to the good.:10;
Incorrect.}]
