{S:b8c6}{D:1000}{S:d5c6}{D:1000}{S:b7c6}{D:1000}{S:b3b4}Question 1 (cont). Yes. This defends the Bishop directly, but on the surface seems to lose the Bishop to 2. Bxc6 bxc6 3. Qxb4. What is Black's response to 3. Qxb4? Click "Next" for the answer.]

{A:Ba8b8}{D:1000}{R}{S:a8b8}
2... Rb8! 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]

Question 2 of 7. How should Black get out of check? Click "Next" for the answer.]

[{B:rnbqk2r/pp2npbp/3p2p1/3Pp3/QpP1P3/3B1N2/P4PPP/RNB1Q2R BLACK}{A:Bd8d7}{D:1000}{R}{S:d8d7}
1... Qd7! 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.]

[{B:3r2k1/4n1p1/7p/1p2pp2/2p1Pq2/2Pr1P1P/1PQ3PK/R3RN2}
Question 3 of 7. How should White get out of check? Click "Next" for the answer.]

[{B:3r2k1/4n1p1/7p/1p2pp2/2p1Pq2/2Pr1P1P/1PQ3PK/R3RN2}{A:Wh2h1}{D:1000}{R}{S:h2h1}
1. Kh1. 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.]

[{B:3r2k1/5pp1/7p/pB6/Q3q3/P2nPN2/1K3PPP/2R5}
Question 4 of 7. How should White get out of check? Click "Next" for the answer.]

[{B:3r2k1/5pp1/7p/pB6/Q3q3/P2nPN2/1K3PPP/2R5}
{A:Wb2b1}{D:1000}{R}{S:b2b1}
1. Kb1! White's move seems absurd because it allows Black to give a discovered check. But after 1... Nb4+ White finds some peace with 2. Ka1. Black's attack has been halted and White's material edge should prove decisive.]

[{B:5B1k/1p1q3p/3p1P2/p1p1b3/P1PnP3/1P5Q/1r5P/5R1K BLACK}
Question 5 of 7. What is Black's best move? Click "Next" for the answer.]

[{B:5B1k/1p1q3p/3p1P2/p1p1b3/P1PnP3/1P5Q/1r5P/5R1K BLACK}{A:Bb2h2}{D:1000}{R}{S:b2h2}
1... Rxh2+! 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.]

[{B:3N4/16/3b4/6K1/5p2/8/7k}
Question 6 of 7. Is there a move that lets White force a draw? Click "Next" for the answer.]

13.
[{B:3N4/16/3b4/6K1/5p2/8/7k}{A:Wg4g3}{D:1000}{R}{S:g4g3}1. Kg3! After the compulsory 1... Kg1, White secures the draw by 2. Ne6! f2 3. Nf4! f1/Q 4. Nh3+ Kh1 5. Nf2+ Kg1 6. Nh3 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.]

{D:750}{S:a3a2}{D:750}{S:g2g3}
{D:750}{S:a2a1}{X:a1}{P:BQa1}
1. f4! 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.Remarkably, White draws by 2. fxg5 a4 3. Kg3 a3 4. Kh4 a2 5. g3 a1/Q. Guess what? It's stalemate! White has entombed his own King.]
