9W0001 How to read chess notation. 1. Qd7+ Kb6 2. Rc1 Qxd2 3. Qc6+ Ka5 4. Ra1+ Kb4 5. Ra4+ Kb3 6. Qc4+ Kb2 7. Ra2+ Kb1 8. Qb3+ Kc1 9. Ra1++	_____	9W0002 1. Qxc7+ Kxd5 2. Qd7+ Ke4 3. Qe6+! and now not Kxd4 because of 3. ... Qb6+ winning the queen on f2. So 3. ... Kf4 4. Qxf6+ Ke3 5. Qxf2+ Kxf2 6. d5 and the pawn queens on move 9.
9W0003 1. Rc4! forces a trade of rooks (i.e. Rd6 2. Rc7+) So 1. ... Rxc4 2. dxc4 is a won endgame for white. What will happen is white will march his king to d3. He can expect to win the pawn around move 9.	_____	9W0004 This is a matter of propper king opposition. 1. Rxf6+ Kxf6 2. Kd4 Ke6 3. Ke4 Kf6 4. Kd5 Kf7 5. Ke5 Kg6 6. Ke6 Kg7 7. Kf5 Kh6 8. Kf6 and 9. Kxg5 wins. The pawn on f3 is unnecessary to win this.

9W0005 1. hxg7 Rxh1+ 2. Kf2 Rxa1 3. f5!!!! Bd7 (if exf5 Nxd5 and Nf6++) 4. f6 Bd8 5. Qh6 Bd7 (Kf7 g8=Q) 6. Qh8+ Kf7 7. Qxa8 Be8 8. g8=Q Kxg8 9. Qxe8+ Kh7 10. Qf7+ Kh6 11. Qg7+ Kh5 12. f7 and 13. f8=Q and 14. Q8h8 mate	_____	9W0006 1. Rxd7 and now if Qxd7 2. Qxa6 with a better position or 1. ... Kxd7 2. Qd1+ Ke8 3. Bd6 with a great position or 1. ... bxa4 2. R1xe7+ Kf8 3. Rxf7+ Kg8 4. Rxg7+ Kf8 5. Bd6+! Ke8 6. Rge7+ Kf8 7. Rxh7+ Ke8 8. Rde7+! Kd8 9. Rxh8+ forces mate
9W0007 1. Bh3! Rg7 (much worse is Rg8 and less resistance is Rg6) 2. Bxf5 and now if exf5 3. Nxd5 is crushing, i.e. 3. ... Qd8 (Qc8 Nb6) 4. Nf6+ forcing Kf8 and then Nxd7+. So instead 2. ... d4 3. Nf6 exf5 4. Nd6+ Kf8 (Ke7 Rxb7) 5. Qh3! Ke7 6. Qh4+ Kf8 7. Qh8+ Rg8 8. Qh6+ and now Rg8 9. Rg1 or Ke7 9. Qf6+ leads to mate.	_____	9W0008 1. Bxg6!! with the threat of Qh7 mate or leading to mate. So then forced is 1. ... Rh8 But now 2. Qg4!! is very strong. Then if 2. ... Kf8 3. Ne6+ fxe6 4. Qf4+ and 5. Qf7 mate. Black might be able to give up his Queen to avoid mate. If instead 2. ... Rg8 Chess Master 400 thinks that 3. Bf5! produces mate around move 9. There may be alternatives to 2. Qg4 which include 2. Qf5!? and 2. Nh7!
9W0301 [solution]	_____	9W0302 [solution]      [Next]
