5W0043 [solution]	_____	5W0044 [solution]      [Next]
5W0041 1. Qe6 Qxe6 2. Rxe6 Rxe7 3. Rd6 with double threat on the knight and mate. 3. ... Rxf7 4. Rd8+ mates on move 5. Some have suggested that 1. Bxe8 Nxe3 2. Bc6 Qe6 3. e8=Q is a better solution.	_____	5W0042 1. ... h4+ and no good now is 2. Kg4 Kf2 3. Kxg5 Kg3 winning. So instead 2. Kg2 and black follows a standard outflanking maneuver. 2. ... Kf2 3. Kg1 f3 4. Kh2 Kf2 5. Kh1 Kg3 wins the pawn and the game.
5W0043 1. Bxh5 now if Kg7 2. Bxg6! and if 2. ... Rh8 3. Qg4!! wins If 3. ... Kf8 4. Ne6+ fxe6 5.Qf4+ wins. If 3. ... Rg8 4. Ne6+ fxe6 5. Bh5+ wins. If 1. ... Qe7 then 2. Be2!! wins. Now if 2. ... f6 3. Bc4+ wins	_____	5W0044 1. Rh2+ Kg4 2. Rxg3+ Kxg3 3. Rg2+ Kh3 4. Rxg7. White has won a pawn and has the better endgame. Black has the unpleasant choice of trading rooks (with a lost endgame) or losing the c7 pawn on move 5.

5W0045 1. Rd6+ is the fastest. If 1. ... Kc7 2. Rc1+ Kb8 3. Rd8 mate. If instead 1. ... Kc5 2. Re5+ Kc4 (not Kb4 3. Rd4 mate) 3. b3+ and now 3. ... Kb4 4. Rd4 mate or 3. ... Kc3 4. Re3+ Kb4 5. Rd5 mate!	_____	5W0046 No good is a king move that would stalemate. 1. Qf3+ Kg1 2. Ke2! now if the pawn promotes to anything but a knight, then 3. Qf2 mate so 2. ... h1=N 3. Qf1+ Kh2 4. Kf3 mates next move with 5. Qg2 mate
5W0047 1. Ra4+ Kb3 2. Qc4+ (I call this a stair-step mating patern.) Kb2 3. Ra2+ (another step) Kb1 4. Qb3+ Kc1 5. Ra1 mate Actually faster is 1. Rb1+ but I wanted to illustrate the above technique which I call the "stair step mate."	_____	5W0048 Correct me if I am wrong. I think that White can try to win the a5 pawn but also has to stop black from winning the c4 pawn. So if 1. Ka4 Kd6 2. Kb5! now the knight if free to play for Nd4 and c6 winning the pawn on move 5. If Ne8 3. c5+!?

5W0051 [solution]	_____	5W0052 [solution]      [Next]
5W0049 1. b6! The rules is that two pawns on the 6th rank beat a rook. Black can check the white king many times but it doesn't help. The alternatve is 1. c7! Rc5 2. b6! axb6 3. axb6 with the threat of 4. b7! threatening to queen a pawn on move 5.	_____	5W0050 Interesting is 1. Rxd8 Nxd8 2. Bb8 winning the rook. Also interesting is 1. Bxc6 leaving the rook hanging on d8. Now 1. ... Rxd1 2. Rxd1 and now bxc6 is a very bad idea for black because of 3. Rd8+ Bf8 4. Bh6 forcing 5. Rxf8 mate.
5W0051 This is more complicated than it first looks. 1. Rd8 Kf7 2. Qe6+ Kg7 3. Rxe8 fails to 3. .. Qf2+ which gets a perpetual check. So instead 1. Rd8 Kf7 2. Rxe8! Kxe8 3. Qg3!! threatens a 4th move queen check and a pawn queen on move 5.	_____	5W0052 1. Bxf5 gxf5 2. f7+!! and now if Kxh7 3. f8=Q as double threat of Qh8 mate and Qg7 mate. So if 2. ... Kf8 3. Bd2 and black may have to give up his rook to stop 4. Bh6+ and 5. f8=Q. Coffey vs. Eric Hamond, 1996 Utah Amateur Championship, board 1.

5W0055 [solution]	_____	5W0056 [solution]      [Next]
5W0053 1. Qf5+ and now if 1. ... Ke8 2. Qc8+ Kf7 3. Qxh8 Kxg6 4. Qxd4 with a won position. If instead 1. ... Ke7, then 2. Re6+ Kd8 (Kd7 is worse because of Rh6+) 3. Qd5+ Bd6 (so as to be able to play kd7) 4. Rxd6+ cxd6 5. Qa8+ with a skewer.	_____	5W0054 There might be other solutions, but a neat mate in 5 is 1. Bc7+ Kxc7 2. Nd5+ and black can flee to 3 squares all of which are bad. 2. ... Kd8 3. Rxc6 and then 4. Rd6 mate. 2. ... Kb8 3. Qxc6 forces mate. So 2. ... Kb7 3. Qxc6+ Ka6 4. Nb4+ Ka5 5. Qa4 mate.
5W0055 1. Qf5+ and now if 1. ... Ke8 2. Qc8+ Kf7 3. Qxh8 Kxg6 4. Qxd4 with a won position. If instead 1. ... Ke7, then 2. Re6+ Kd8 (Kd7 is worse because of Rh6+) 3. Qd5+ Bd6 (so as to be able to play kd7) 4. Rxd6+ cxd6 5. Qa8+ with a skewer. Thanks to Eon on FICS.	_____	5W0056 Apparently the best way is to just overwhelm black with pawns. The white king doesn't really participate much in the attack. 1. b6 and not Kc8 2. b7+ Kb8 3. d7 Kc7 4. d8=Q+ Kxd8 5. b8=Q. If instead 1. ... Ra5+ then the king flees and he plays b7 (followed by c7) at his convenience.
5W0057 [solution]	_____	5W0058 [solution]      [Next]
5W0057 Crafty (comptuer) vs. Grand Master Heine in a 3 minute game at the Internet Chess Club. 1. Qf7! Black resigns. i.e. 1. ... Kb8 2. Bxa7+ Ka8 3. Bc5+ Kb8 4. Rb1+ forces mate. The threat is 5. Qb7 mate. Black can give up two pieces to delay it, but it hardly matters. If 1. ... a5 2. Rxa5! wins	_____	5W0058 the position is complicated. White can win the exchange by taking on e7 but there is better. he would like to play Qh4 threatening mate but the response of f6 threatenes Rh7. It appears that the best is 1. Nxd8! Qxd8? 2. Qh4 f6 3. Bxh6 Rh7 4. Bxd8 Rxh4+ 5. Bxh4 Other variations are possible.
