4W0061 1. Rxa2 Qxa2 2. Bb2 or 1. Bb2 Nf6 (to stop mate) 2. Rxa2 Qxa2 3. Ra1 traps the queen. No good now is 3. ... Ne4 allowing 4. Qg7 mate.	_____	4W0062 1. Bg5 wins easily now if f6 then 2. exf6 has huge threat of 3. f7+ Rxf7 4. Qxf7+! If Black tries 2. ... Rf7 3. Qg8+ Rf8 4. f7 mate!
4W0063 Of course white can queen the pawn if he wants, but much faster is 1. Bc5! Kh8 2. Bd6! (a waiting move) Kg8 3. a7+ Kh8 4. Be5 mate.	_____	4W0064 1. Qd5+ Kh8 2. Qxa8!! and now if 2. ... Rxa8 (everything else looks bad too) 3. Rd8+ Rxd8 4. Rxd8 mate!!! Thanks to woodbury for this neat combo!

4W0067 [solution]	_____	4W0068 [solution]      [Next]
4W0065 1. Kc4! and now the threat of Rc7 mate can only be stopped by 1. .... Rc8 and now 2. Rg7 threatens 3. Ne7+ and 4. Nxc8+ and black is powerless to stop it.	_____	4W0066 1. Nf6+ black should give up the queen to stop immediate mate. If Kh8 (kf8 dies the same way but faster) 2. Re8+ Rxe8+ 3. Qxe8+ Qg8 4. Qxg8 mate
4W0067 1. Bxe5 forks two rooks. Nothing black can do can prevent the capture of one of the rooks. I.e. 1. ... Bxb5 2. Qxb5+ Qd7 3. Qxd7+ Rxd7 4. Bxh8	_____	4W0068 1. d5+ Kd6 2. Kf5 (proximity to the pawns is important) Ke7 3. d6+ Kxd6 4. Kxf6 and then the other two black pawns will drop as well. White wins.

4W0071 [solution]	_____	4W0072 [solution]      [Next]
4W0069 1. Nxe6 threatening mate and the rook on d8. 1. ... exf6 2. Qxe6+ Kh7 3. Rxc6 winning exchange. Now 3. ... Rxc6 4. Rxc6 and powerful threats on g6.	_____	4W0070 1. Nxd6+ (the queen is pinned) and now the king moves and 2. Rxb7+ will trade a rook and a knight for a Queen and two pawns by move 4. Not a bad trade.
4W0071 1. Qe7+ and 2. Ne6 will mate on move 3 regardless of the black defense. The longest line is 1. Qe7+ Bf7 2. Ne6+ Kh8 3. Qf8+ Bg8 and now 4. Qg7 mate or 4. Qf6 mate	_____	4W0072 1. Qxc8!! and Black is helpless to 2. Qxf8+ If 1. ... Ne8 then 2. Qxe8! if 1. ... Rxc8 2. Rxc8+ Ne8 3. Rxe8 mate. Moves like 1. ... Nc2+ or 1. ... Nd3+ just delay the result to move 4.

4W0075 [solution]	_____	4W0076 [solution]      [Next]
4W0073 The key here is that white will mate black if he can force the queen off of the 2nd rank. 1. Bf5 Qh5+ 2. g4 Qh8 3. Qd7+ Kb8 4. Qd6 mate. But if 1. ... e4 does d4 get the same thing?	_____	4W0074 1. Bc5 was pretty convincing. If the knight takes the bishop then trade both rooks and queen the b7 pawn on move 4. Otherwise the threat of Rxd7 double check is strong. If 1. ... Ke8 2. Rxd7! wins.
4W0075 1. Rf5 trapping the Queen for now. 1. ... Nxe4 2. Rxe5 Nxd2 3. Rxe7 which not only wins a piece but will win the knight on move 4. The knight has no way to escape as the c4 square is covr	_____	4W0076 Not d8=Q stalemate so instead 1. Bf5 Kh8 2. d8=Q+ Kh7 3. Qg8 mate. If white wanted to get REALLY FANCY he could play 1. d8=N !?!? (promotes to a knight) Kh8 2. Ne6 Kh7 3. Nf8+ Kh8 4. Bh6 mate. Of course it takes longer. :-)

4W0079 [solution]	_____	4W0080 [solution]      [Next]
4W0077 1. Qb5!!! and black can't take the queen because 2. Ra8+ forces mate on mvoe 4. If the Black queen moves out of danger then the rook on d7 drops. Of little help is 1. ... Qxe4 2. Rxd7 Qf4+ 3. Kg1 Qc1+ 4. Qf1 wins.	_____	4W0078 1. Rxf6 prevents Qxf2+ and gives white a crushing attack. Even after 1. ... Qb1+ 2. Kh2 black is still helpless against the threat of 3. Bd5+ leading to mate. If 1. ... Qh5 2. Bd5+ Kg7 3. Rf7+ Qxf7 4. Bxf7 wins
4W0079 1. Rxf7! with the threat of Rxg7+ leading to mate on move 4. So if 1. ... Rxc7 2. Rxc7 wins the pawn on c3. If instead 1. ... Rxf7 2. Rxc8+ wins the pawn on c3. White goes from being a pawn down to being a pawn up.	_____	4W0080 1. Qe4+ (to drive the king further out.) if 1. ... Kh6 2. Nf7+ Kh5 3. Be2+ Kh4 4. Qxf4 mate if 1. ... Kh5 2. Be2+ Kxg5 (If Kh6 then Nf7 mate) 3. Bxf4+ Kh4 4. Bh6 mate if 1. ... Kxg5 2. Bxf4+ Kh5 3. Be2+ is the same
