1... Kc3! It's strange, but by stalemating White's king Black puts his opponent in a helpless situation. White is forced into a commital action, whereupon Black wins by moving his a-pawn either one or two squares, depending on how White plays his a-pawn. If White moves his a-pawn one square, 2. a3, then Black wins by moving his a-pawn two squares: 2... a5 3. a4 Kb3 (or 3... Kd3), and Black soon queens the c-pawn. (Full credit also for 2... Kb3 3. a4 a5 or 2... Kd3 3. a4 a5.)]

[{B:16/4Bk1P/16/4K3/16}{A:We6f5}{D:1000}{R}{S:e6f5}1. Bf5! This prevents Black from attacking the pawn. After 1... Kf7 White wins by: 2. Bh7! Kf6 3. Kf4, and Black cannot get to the corner to stop the pawn. White soon promotes it.]

{A:Ba1b3}{D:1000}{R}{S:a1b3}1... Nb3+! After White takes the knight, 2. cxb3, Black wins by outflanking, 2... Ke4 3. Kd2 (or 3. Kc2 Ke3) 3... Kd4 4. Kc2 Ke3 5. Kc1 Kd3 6. Kb2 Kd2 7. Kb1 Kc3 8. Ka2 Kc2 9. Ka1 Kxb3 10. Kb1 Ka3 (this is better than 10... Kc3, which wastes time) 11. Ka1 b3 12. Kb1 b2]

[{B:4k3/8/6PK/4p3/1b6/7B/16}{A:Wh3d7}{D:1000}{R}{S:h3d7}1. Bd7+! 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. ]

Question 5 of 7. What is Black's best move? Click "Next" for the answer.]

[{B:1k6/16/PPP5/7p/5p2/6pK/8 BLACK}{A:Bg2g1}{D:1000}{R}{S:g2g1}{X:g1}{P:BQg1}1... g1/Q+! After White takes the queen, 2. Kxg1, Black wins by 2... h3. 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. a7, then 2... Ka7. Or if 2. b7, then 2... Kb7. White runs out of moves and loses.]

[{B:8/B7/7P/4p3/7k/8/2K5/b7}
{A:Wa7d4}{D:1000}{R}{S:a7d4}1. Bd4! A sly move that enables White to create an obstacle preventing Black's bishop from guarding the h-pawn's promotion square at h8. If Black takes with the pawn, 1... exd4, White blocks the line with 2. Kd3, and the pawn goes through. And if Black instead takes with the bishop, 1... Bxd4, White wins with 2. Kd3 Black will not be able to stop White from obstructing the position by Kd3-e4, so the pawn goes through.]
