5W0037 [solution]	_____	5W0038 [solution] [Next]
5W0039 [solution]	_____	5W0040 [solution] [Next]
5W0037 1. Rb8 Bc6 2. Na2 a5 3. b4 axb4 4. Nxb4 and white will win at least a pawn. If 3. ... a4 4. b5! Bxb5? 5. Rxb7 wins a piece. If instead 1. ... b5?? 2. Rb7 wins a piece.	_____	5W0038 1. Rd2 (to prevent Qxb2 mate) Now if 1. ... Qxg3 then 2. Qxf7+ Kd8 3. Qf6+ forks the king and the rook. If instead 1. ... Qf6 2. Rf1! Qe7 3. Rxf7 Qd6 4. Rd7+ (or Rf8+!) Kf8 5. Qf7 mate!
5W0039 1. Rf6! and the threat of 2. Qxh6+ gxh6 3. Rxh6 mate is too much. if 1. ... Kh7 2. Rxg7+ Kxg7 3. Qxh6+ Kg8 4. Qg5+ Kh7 5. Rh6 mate. If instead 1. ... g6 2. Qxh6+ Kg8 3. e6! is crushing.	_____	5W0040 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.

5W0043 [solution]	_____	5W0044 [solution] [Next]
5W0041 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.	_____	5W0042 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
5W0043 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.	_____	5W0044 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!
5W0045 [solution]	_____	5W0046 [solution] [Next]
5W0047 [solution]	_____	5W0048 [solution] [Next]
5W0045 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	_____	5W0046 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."
5W0047 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.	_____	5W0048 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.
