3W0163 [solution]	_____	3W0164 [solution]      [Next]
3W0161 1. f8=Q only stalemates. So instead 1. Kf6! (also Ke8 works too.) 1. ... Kh8 2. f8=Q+ Kh7 and now 3. Qg7 mate or 3. g6 mate	_____	3W0162 1. Rxc7 and the Queen can't move because of the mate threat on g7. If 1. ... Rf5 2. Rxd7 Rxe5 3. Rxd8+ wins No good is 1. Re7 Qg4
3W0163 1. Nxd5 and now if 1. ... Qc8 2. Nb6. If instead 1. ... Qd8 then 2. Nf6+ and now not Ke7 allowing 3. Qd6 mate so instead 2. ... Kf8 3. Nxd7 wins	_____	3W0164 white gets at least at least a two pawn advantag and great position after 1. cxd5 bxc5 2. dxe6 Qe7 3. exf7+ is 1. Bxd5 a viable alternative?

3W0167 [solution]	_____	3W0168 [solution]      [Next]
3W0165 1. Qg6!! threatens Qh7 mate and can't be taken because the f7 pawn is pinned by the g3 bishop. Now 1. ... Nf6 2. exf6 or Nf6+ forces mate on move 3.	_____	3W0166 1. Bd6!! threatens two pieces. If 1. ... Qxd6 2. Bxg6! threatens both the Queen and mate on move 3. No good is 2. ... Qxd1 3. Qxf7 mate.
3W0167 1. Rd8+ Kxd8 2. Kxf7 and the bishop must move so the pawn falls on g7 . if 2. ... g5 white has more than one good option including 3. Kxf8 and 3. Bxg5	_____	3W0168 1. Bxg6!! If 1. ... Rxg3 2. Rxb8 mate. If instead 1. ... hxg6 2. Rxb3 wins material. If instead 1. ... Rxb1+ 2. Rxb1 Rxb1+ 3. Bxb1 wins
3W0169 [solution]	_____	3W0170 [solution]      [Next]
3W0171 [solution]	_____	3W0172 [solution]      [Next]
3W0169 1. Nxh6+! gxh6 (Kh7 2. Nf7+ forces mate) 2. Qxh6! and black can't avoid mate next move. 2. ... Nf7 3. Qh7 mate. Also works is 2. Qg6+.	_____	3W0170 There seems to be more than one way to win, including 1. Rg8 and 1. Rh8 The simplest seems to be 1. Rg8 and 2. Kf3 winning the pawn on move 3.
3W0171 1. Bd6+ and now if the king moves to rank 5 then Rd5+ wins the knight. If instead 1. ... Kb4 2. Rd4+ Kc5 (or Kb5) 3. Rd5+ wins the knight.	_____	3W0172 1. b3 threatens to win a2. If now Qa5 then 2. Nxd6+ Kd7 3. Nxf7 wins two pawns and still gives white a strong position with a favorable attack.
3W0173 [solution]	_____	3W0174 [solution]      [Next]
3W0175 [solution]	_____	3W0176 [solution]      [Next]
3W0173 1. Nd5 threatens the Queen and threatens the fork with Nxc7+. So if 1. ... Qd8 2. Nf6+!! threatens 3. Qxf7 mate. So 2. ... Qxf6 is forced to prevent mate.	_____	3W0174 1. Rh4! threatens Bf8 mate. So if 1. ... Rh7 2. Bd3 wins the rook on move 3. If instead 1. ... Kh7 2. Bd3+ Rg6 3. Bxg6+ with a winning advantage.
3W0175 White can't queen his pawn because the queening square is attacked by the enemy queen. But after 1. Nf5+ Kg6 (Kf8 2. Rd8 mate) 2. Rd6+ f6 3.b8=Q wins	_____	3W0176 1. f5+ Kd5 and white mistakenly thought 2. c4+ was checkmate but now dxc3 3. Nxc3 is mate. Instead 2. Qf7+ is a very impressive win but takes longer.
3W0177 [solution]	_____	3W0178 [solution]      [Next]
3W0179 [solution]	_____	3W0180 [solution]      [Next]
3W0177 1. Rxf5 (white played Bxf5 and won anyway) threatens both the queen and 2. Rf8+! leading to mate on move 3. Black can dealy things with 1. ... Nxg3+ but it hardly matters.	_____	3W0178 the easy way is 1. Bh5+ and now if 1. ... Kf8 2. Qf3+ or Qf4+ forces mate after king moves and 3. Qf7 mate. Black can give up his queen to delay mate but it hardly matters here.
3W0179 h4, a3 or Kc5 all easily win the pawn on d5.	_____	3W0180 1. Ba6!!!!! Black can't take the bishop because of Rb8 mate. But White still threatens Rb8 mate. So ... 1. .... Nb6 2. Rxb6+ Rxa6 (not Kc7 3. Rb8 mate.) 3. Rb8 mate anyway.
