[{B:8/p7/24/3k4/P1p5/2K5 BLACK}
{VB:Question 1 of 7. What is Black's best move?;
d3c3;Correct. It's strange, but by stalemating White's King, Black puts his opponent in a helpless situation.:4;
Incorrect.{JD:10};
a7a5:Incorrect. This fails to win anything after 2. a4, when 2... Kc3 is what chessplayers call stalemate. The game is drawn.{JD:10}:0;
a7a6:Incorrect. White draws by proceeding like a snail, 2. a3!. Now the game is drawn. Both 2... a5 3. a4 Kc3 stalemate, as well as 2... Kc3 3. a4 Kb3 (or 3... Kd3) 4. a5 fail to promote the c-pawn.{JD:10}:0}]

Incorrect.{JD:10};
c3b3:Correct.{JD:4}:0;
c3d3:Correct.{JD:5}:0}]

3.
[{M:B}{S:a3a4}
{VB:Question 1 (cont). If White moves 3. a4, what is Black's best move?;
c3b3;Correct. And Black soon queens the c-pawn.{JD:6}:3;
Incorrect.{JD:10};
c3d3:Correct. And Black soon queens the c-pawn.{JD:6}:3}]

4.
[{M:B}{S:a3a4}
{VB:Question 1 (cont). If White moves 3. a4, what is Black's best move?;
a7a5;Correct. And Black soon queens the c-pawn.{JD:6}:3;
Incorrect.{JD:10}}]

[{M:B}{S:a3a4}
{VB:Question 1 (cont). If White moves 3. a4, what is Black's best move?;
a7a5;Correct. And Black soon queens the c-pawn.{JD:6}:3;
Incorrect.{JD:10}}]

[{B:8/p7/16/P7/2k5/2p5/2K5 BLACK}
{VB:Question 1 (cont). If White moves his a-pawn two squares, 2. a4, what is Black's best move?;
a7a6;Correct.:0;
Incorrect.{JD:10};
c3b3:Correct.{JD:8}:0;
c3d3:Correct.{JD:9}:0}]

7.
[{M:B}{S:a4a5}
{VB:Question 1 (cont). If White moves 3. a5, what is Black's best move?;
c3b3;Correct. And again the c-pawn will promote.{JD:10}:3;
Incorrect.{JD:10};
c3d3:Correct. And again the c-pawn will promote.{JD:10}:3}]

8.
[{M:B}{S:a4a5}
{VB:Question 1 (cont). If White moves 3. a5, what is Black's best move?;
a7a6;Correct. And again the c-pawn will promote.{JD:10}:3;
Incorrect.{JD:10}}]

[{M:B}{S:a4a5}
{VB:Question 1 (cont). If White moves 3. a5, what is Black's best move?;
a7a6;Correct. And again the c-pawn will promote.{JD:10}:3;
Incorrect.{JD:10}}]

[{B:16/4Bk1P/16/4K3/16}
{VB:Question 2 of 7. What is White's best move?;
e6f5;Correct. This prevents Black from attacking the pawn.:5;
Incorrect.{JD:12};
e6g8:This is not the best move. After 1... Kg6 2. h7 Kg7, the game is drawn because White has the wrong Bishop, which can't attack the dark square at h8.{JD:12}:1;
e3f4:This is not the best move. This is tricky, for if Black takes the Bishop the pawn queens. But the simple 1... Kg6 gobbles the pawn, and the game is drawn by insufficient mating material.{JD:12}:1;
h6h7:Incorrect. Black has a positional draw after retreating his King to g7, for White's Bishop can't guard h8. The pawn therefore can't be promoted by force.{JD:12}:0}]

11.
[{M:W}{S:f6f7}
{VB:Question 2 (cont). After 1... Kf7, what is White's next move?;
f5h7;Correct. 2. Bh7! is followed by Kf6 3. Kf4, and Black cannot get to the corner to stop the pawn. White soon promotes it.:5;
Incorrect.}]

12.
[{B:24/4k3/1p6/8/2P5/n1K5 BLACK}
{VB:Question 3 of 7. What is Black's best move?;
a1b3;Correct.:5;
Incorrect.{JD:21};
a1c2:This is not the best move. It gains a pawn for the Knight, but White's King can still hold the draw after 2. Kxc2 Kd4 3. Kb3 Kc5 4. Kb2.{JD:21}:1;
e5d4:This is not the best move. Black plans to sacrifice his Knight for the pawn, but no real progress can be made after 2. Kb2 Nxc2 3. Kxc2 Kc4 4. Kb2 b3 5. Kb1.{JD:21}:1}]

13.
[{S:c2b3}{M:B}
{VB:Question 3 (cont). After White takes the Knight, 2. cxb3, what is Black's next move?;
e5e4;Correct.:0;
Incorrect.{JD:21}}]

14.
[{M:B}{S:c1d2}
{VB:Question 3 (cont). After White moves 3. Kd2, what is Black's next move?;
e4d4;Correct.:0;
Incorrect.{JD:21}}]

15.
[{M:B}{S:d2c2}
{VB:Question 3 (cont). After White moves 4. Kc2, what is Black's next move?;
d4e3;Correct.:0;
Incorrect.{JD:21}}]

16.
[{M:B}{S:c2c1}
{VB:Question 3 (cont). After White moves 5. Kc1, what is Black's next move?;
e3d3;Correct.:0;
Incorrect.{JD:21}}]

17.
[{M:B}{S:c1b2}
{VB:Question 3 (cont). After White moves 6. Kb2, what is Black's next move?;
d3d2;Correct.:0;
Incorrect.{JD:21}}]

18.
[{M:B}{S:b2b1}
{VB:Question 3 (cont). After White moves 7. Kb1, what is Black's next move?;
d2c3;Correct.:0;
Incorrect.{JD:21}}]

19.
[{M:B}{S:b1a2}
{VB:Question 3 (cont). After White moves 8. Ka2, what is Black's next move?;
c3c2;Correct.:0;
Incorrect.{JD:21}}]

20.
[{M:B}{S:a2a1}
{VB:Question 3 (cont). After White moves 9. Ka1, what is Black's next move?;
c2b3;Correct. After this follows 10. Kb1 Ka3 (this is better than 10... Kc3, which wastes time) 11. Ka1 b3 12. Kb1 b2:5;
Incorrect.}]

21.
[{B:4k3/8/6PK/4p3/1b6/7B/16}
{VB:Question 4 of 7. What is White's best move?;
h3d7;Correct. If 1... Kxd7, White's g-pawn queens. While 1... Kf8 ( or 2... Ke7 3. g7 Kf7 4. Kh7) 2. g7+ Kf7 ( or 2... Kg8 3. Be6#) 3. Kh7 also promotes the pawn.:10;
Incorrect.;
g6g7:This is not the best move. Its the obvious move, but it doesn't work because Black has the crafty save, 1... Bf8!, pinning the pawn and reducing to a drawn position.:1;
h6h7:This is not the best move. It avoids Black's crafty pin defense (1. g7 Bf8!), but Black holds the position with 1... Bf8 anyway.:1;
h6g7:This is not the best move. Black keeps it together with 1... Bf8+, and the pawn is going nowhere.:1;
h3e6:Incorrect. White temporizes, but the game is drawn with 1... Bf8+, for 2. g7 Bxg7+ 3. Kxg7 is unwinnable without Black's full cooperation.:0}]

22.
[{B:1k6/16/PPP5/7p/5p2/6pK/8 BLACK}
{VB:Question 5 of 7. What is Black's best move?;
g2g1Q;Correct. After White takes the Queen, 2. Kxg1, Black can win.:10;
Incorrect.{JD:24};
b8a7:This is not the best move. Now it is White who wins after 2. c6. For example, if 2... Kb8, one winning line is 3. a6 h3 4. Kg1, and White soon queens.{JD:24}:1;
b8c7:This is not the best move. White turns the tables with 2. a6, which eventually will lead to promoting a pawn, as in 2... h3 3. Kg1 Kb8 4. c6.{JD:24}:1;
b8a8:This is not the best move. White pushes his most distant pawn (2. c6), which eventually produces a new Queen. Black doesn't win. Instead he loses.{JD:24}:1;
b8c8:This is not the best move. The game is now won for White after 2. a6. Try it and see.{JD:24}:1;
b8b7:This is not the best move. With 2. b6 h3 3. Kg1, Black soon runs out of good moves. White wins.{JD:24}:1}]

23.
[{M:B}{S:h2g1}
{VB:Question 5 (cont). After White takes the Queen, 2. Kxg1, what is Black's winning move?;
h4h3;Correct. This wins no matter how White continues. If he moves his King to the h-file, Black's f-pawn queens. If he instead moves the King to the f-file, Black's h-pawn queens. And if he instead moves a pawn, Black stops all the pawns by moving his King directly in front of the moved pawn. For example, if 2. a6, then 2... Ka7. Or if 2. b6, then 2... Kb7. White runs out of moves and loses.:5;
Incorrect.}]

24.
[{B:8/B7/7P/4p3/7k/8/2K5/b7}
{VB:Question 6 of 7. What is White's best move?;
a7d4;Correct. A sly move that enables White to create an obstacle preventing Black's Bishop from guarding the h-pawn's promotion sqaure at h8. If Black takes with the pawn, 1... exd4, White blocks the line with 2. Kd3, and the pawn goes through.:12;
Incorrect.{JD:26};
c2b1:This is not the best move. It actually retains the win, but not because of itself. Rather because White still has the time to get back into the original position to win in the right way. After 1... Bc3 2. Kc2, we're back where we started.{JD:26}:3;
h6h7:Incorrect. White's precipitous advance allows Black to hold with 1... e4, clearing the a1-Bishop's line of retreat.{JD:26}:0;
c2d3:Incorrect. Black salvages a draw by 1... sacrificing the pawn, 1... e4+ 2. Kxe4 Kh5 (or 3... Kg5) 3. h7 Kg6, and the h-pawn soon disappears. White can try to keep his pawn by 3. Be3, but Black draws with 3... Kg6.{JD:26}:0;
a7f2:Incorrect. A meaningless check that permits Black to catch the pawn. Black's King gets back in time after 1... Kh5 2. Be3 Kg6, as well as after 2. h7 e4, followed by 3... Kg6.{JD:26}:0}]

25.
[{M:W}{S:a1d4}
{VB:Question 6 (cont). And if Black instead takes with the Bishop, 1... Bxd4, how does White win?;
c2d3;Correct. Black will not be able to stop White from obstructing the position by Kd3-e4, so the pawn goes through.:8;Incorrect.}]

26.
[{B:8/p1k3p1/16/K3n3/P1P5/6P1/5B2 BLACK}
{VB:Question 7 of 7. What is Black's best move?;
c7b6;Correct. A subtle move, that leads either to mate or the win of the Bishop.:15;
Incorrect.;
e4c3:This is not the best move. It wins a pawn, but Black wants more than that.:1;
e4c5:Incorrect. White escapes after 2. Kb4 Kb6 3. Kc4. No win for Black here.:0;
c7c6:Incorrect. This doesn't really threaten anything, and Black doesn't have time for such frivolity.:0;
e4d2:Incorrect. By this move Black attacks the Bishop, but White is perfectly okay. In fact, Black must be careful his Knight doesn't get snared after 2. Bd3.:0}]
