[{B:rnbq1rk1/ppp2ppp/5n2/3B4/1b2P3/1Q3N2/PB3PPP/RN3K1R BLACK}
{QB:Question 1 of 7. Can Black safely defend his b4-Bishop by 1... Nc6?;
Yes.;Correct. This defends the Bishop directly.:5;
No.;Incorrect. You have to look beyond the direct 2. Bxc6 bxc6 3. Qxb4 for an indirect defense -- which Black has. Black can regain the piece with accurate play.{JD:4}:0}]

2.
[{S:b8c6}{D:500}{S:d5c6}{M:B}
{VB:Question 1 (cont). After 1... Nc6, what is Black's response to 2. Bxc6?;
b7c6;Correct.:0;
Incorrect.{JD:4}}]

3.
[{M:B}{S:b3b4}
{VB:Question 1 (cont). What is Black's response to 3. Qxb4?;
a8b8;Correct. This regains the piece for 4. Qxb8 fails to 4... Ba6+, winning White's Queen. Moreover, White doesn't save the piece by 4. Qd4 because of 4... Rxb2 anyway. If 5. Qxb2, then Black mates with 5... Qd1+ 6. Ne1 Ba6+ 7. Kg1 Qxe1#:5;
Incorrect.}]

[{B:rnbqk2r/pp2npbp/3p2p1/3Pp3/QpP1P3/3B1N2/P4PPP/RNB1K2R BLACK}
{VB:Question 2 of 7. How should Black get out of check?;
d8d7;Correct. By blocking with the Queen Black is able to achieve a strategic objective via 2. Qxb4 Na6. After White's Queen moves to safety the a6-Knight can occupy the splendid square c5, which affords a terrific overlook of the White camp.:10;
Incorrect.;
b8d7:This is not the best move. Black's move looks reasonable, especially since from d7 the Knight is prepared to swing into position at c5. But White can cope with 2. a3!, intending 3. a3xb4. If Black accepts the pawn, 2... b4xa3, then 3. Bxa3 menaces d6, which is not easily guarded. For example, 3... Qc7 is met by 4. Nc3, aiming for 5. Nb5. Nor is 3... Qb6 much better because of 4. Nc3 followed by 5. Rb1.:2;
c8d7:This is not the best move. This gains superficial time but runs into a hassle after 2. Qxb4, threatening both b7 and d6. There are better first moves for Black. Try to find them.:1;
b7b5:Incorrect. Black sacrifices a pawn for virtually nothing. White's Queen takes both b-pawns and laughs all the way to the bank.:0;
e8f8:You must be kidding. Why forfeit the right to castle? So don't.:0}]

[{B:3r2k1/4n1p1/7p/1p2pp2/2p1Pq2/2Pr1P1P/1PQ3PK/R3RN2}
{VB:Question 3 of 7. How should White get out of check?;
h2h1;Correct. White can hold no matter how Black proceeds. For example, if 1... Rd2, then 2. Nxd2 Rxd2 3. Qc1 Qg5 4. Rg1. Or if 1... Qg5, then 2. Qf2:10;
Incorrect.;
h2g1:Incorrect. This move ends the check but fails to the exchange sacrifice 1... Rd2! 2. Nxd2 Rxd2 3. Qc1 Qg5 4. g4 Qf4, and Black's Queen infiltrates. Note the power of Black's Rook on the exposed seventh rank.:0;
f1g3:Incorrect. White blocks the check but places his Knight in a pin, which is met unpleasantly by 1... Rd2 2. Qc1 Qxf3, exploiting the pin along the seventh rank.:0;
g2g3:Incorrect. White's move is a horrible oversight. It weakens the second rank, allowing a decisive intrusion by 1... Rd2+.:0}]

[{B:3r2k1/5pp1/7p/pB6/Q3q3/P2nPN2/1K3PPP/2R5}
{VB:Question 4 of 7. How should White get out of check?;
b2b1;Correct, even though White's move seems absurd because it allows Black to give a discovered check.:10;
Incorrect.{JD:8};
b2c2:Not the best move. This is a little complicated. Black temporarily goes ahead in material with 1... Rc8+ 2. Kd2 Qxa4 3. Bxa4 Nxc1, though it's not clear how the c1-Knight gets out. White, however, has a better first move.{JD:8}:2;
b2b3:Incorrect. A blunder (as is 1. Ka2), for the Rook at c1 goes with check (Nd3xc1+).{JD:8}:0;
b2a1:Incorrect. By this move White drops the Rook directly-- 1... Qxa4 2. Bxa4 Nxc1.{JD:8}:0;
b5d3:Incorrect. White's move ends the check but loses the Queen. Life has to mean more than this.{JD:8}:0}]

7.
[{M:W}{S:d3b4}
{VB:Question 4 (cont). How should White respond to 1... Nb4+?;
b1a1;Correct. Black's attack has been halted and White's material edge should prove decisive.:5;
Incorrect.}]

[{B:5B1k/1p1q3p/3p1P2/p1p1b3/P1PnP3/1P5Q/1r5P/5R1K BLACK}
{VB:Question 5 of 7. What is Black's best move?;
b2h2;Correct. This wins, not because it gains the White Queen (2. Qxh2 Bxh2), for White in turn wins the Black Queen (3. Bg7+ Kg8 4. f7+ Qxf7 5. Rxf7), but because after 5... Kxf7 6. Bxd4 cxd4 7. Kxh2 Black soon gets a new Queen with 7... d3.:15;
Incorrect.;
d7h3:Not the best move. Black wins the Queen, but not the game, for after 2. Bg7+ Kg8 3. f7+ Kxg7 4. f8/Q+ Kg6 5. Rg1+ Kh5 6. Qf7+ Kh6 7. Qf8+ White has a perpetual check.:3;
d4f3:Not the best move. This is tricky, for taking Black's Queen (2. Qxd7) allows mate, 2... Rxh2#. But the capture 2. Qxf3 lets White escape, 2... Rxh2+ 3. Kg1.:2;
d7f7:Incorrect. Black blocks the advance of the f-pawn, but this loses to 2. Bg7+ Kg8 3. Qc8+.:0}]

[{B:3N4/16/3b4/6K1/5p2/8/7k}
{VB:Question 6 of 7. Is there a move that lets White force a draw?;
g4g3;Correct.:10;
Incorrect.{JD:15};
d8e6:Incorrect. A useful tactical idea, but one here which comes too soon. Black now wins by pushing the pawn and making a new Queen.{JD:15}:0;
d8f7:Incorrect. Black promotes by force after 1... f2.{JD:15}:0;
g4h3:Incorrect. With 1. f2 it's clear that White can't prevent Black from making a new Queen.{JD:15}:0;
d8c6:Incorrect. Black takes the Knight and soon promotes the f-pawn. It's all over.{JD:15}:0}]

[{S:h1g1}{M:W}
{VB:Question 6 (cont). How should White respond to the compulsory 1... Kg1?;
d8e6;Correct.:0;
Incorrect.{JD:15}}]

[{M:W}{S:f3f2}
{VB:Question 6 (cont). How should White respond to 2... f2?;
e6f4;Correct.:0;
Incorrect.{JD:15}}]

12.
[{S:f2f1}{X:f1}{P:BQf1}{M:W}
{VB:Question 6 (cont). How should White respond to 3.... f1/Q?;
f4h3;Correct.:0;
Incorrect.{JD:15}}]

13.
[{M:W}{S:g1h1}
{VB:Question 6 (cont). How should White respond to 4... Kh1?;
h3f2;Correct.:0;
Incorrect.{JD:15}}]

14.
[{M:W}{S:h1g1}
{VB:Question 6 (cont). How should White respond to 5... Kg1?;
f2h3;Correct. White draws by perpetual check with only a Knight against a Queen and Bishop! Note that on 3... Be6 (instead of 3... f1/Q) White holds by 4. Ne2+ Kf1 5. Nf4 Bf5 6. Kf3, and Black can't force a win.:10;
Incorrect.}]

15.
[{B:1k6/8/p5p1/6p1/6P1/5P1P/6PK/8}
{VB:Question 7 of 7. How does White force a draw?;
f3f4;Correct. Now if Black plays 1... gxf4 White Queens first starting with 2. h4. Note that when White Queens at h8 he will be guarding Black's promotion square at a1. So Black's best hope is to try to get there first with 1... a5.:10;
Incorrect.{JD:-1};
h3h4:Not the best move. A reasonable attempt at a swindle, for if Black plays 1... a5, he's beaten to promotion by 2. h5. But Black inserts the capture 2... gxh4, and White gets nowhere after 3. f4 Kc7. Black's King will overtake White's pawns and the a-pawn will eventually Queen.{JD:-1}:2;
h2g3:Incorrect. This is a good idea, but it's out of order. Black now wins with 1... a5. If 2. f4, then 2... gxf4+ 3. Kxf4 a4, and White's King can't catch Black's a-pawn.{JD:-1}:0}]

[{S:a6a5}{M:W}
{VB:Question 7 (cont). How should White respond to 1... a5?;
f4g5;Correct.:0;
Incorrect.{JD:-1}}]

17.
[{M:W}{S:a5a4}
{VB:Question 7 (cont). How should White respond to 2... a4?;
h2g3;Correct.:0;
Incorrect.{JD:-1}}]

18.
[{M:W}{S:a4a3}
{VB:Question 7 (cont). How should White respond to 3... a3?;
g3h4;Correct.:0;
Incorrect.{JD:-1}}]

19.
[{M:W}{S:a3a2}
{VB:Question 7 (cont). How should White respond to 4... a2?;
g2g3;Correct. Black promotes his pawn to a Queen, 5. a1/Q. But guess what? It's stalemate! White has entombed his own King.:10;
Incorrect.}]
