5B0049 1. ... g5 and white can't avoid g4. If the knight on f3 moves then it is still g4 winning the knight on h3. If 2. Ne5 Qc7 and now if 3. Ng6 Rf6 4. Qh5 Kg7 and the knight has run out of squares and will drop on move 5.	_____	5B0050 The game continued 1. ... Rxf2 2. Qxf2 g3 3. Qf5+ Qxf5 4. exf5 gxh2 5. Kxf2 Rg4 forks the pawns and looks like a won endgame to me. If 3. Qe1 (to protect h4) gxh2 4. Kxh2 Rg4 5. Kh3 Rf4 is a little better for black
5B0051 1. ... Ne4+! and now if 2. Kh1? Qxh2+!!! 3. Kxh2 Rg2+ 4. Kh1 Ng3 mate. If instead 2. Kf1 Rg1+!!! and now 3. Bxg1 Nd2 mate, so instead 3. Kxg1 Qg5+! 4. Kf1 Qg2+ 5. Ke1 Qe2 mate. How many people can see this problem all the way through?	_____	5B0052 This is complicated. At some points white can sac material to delay mate but the result is the same. 1. ... Ne4+ and 2. Kh1 or Kf1 then Qh3 fores mate. 2. Kf1 Qh3 3. Ke1 Qxf3! 4. Qf2 or Bf2 Rg1+ 5. Bxg1 Nd3 mate! If U can C this, U master.

5B0053 1. ... Ne5+ 2. Kxe5 Nc6+ (the idea was just to get the pawn out of the so as to open lines to the king.) 3. Kd3 or Kd5 and then Qd8+ 4. Kc5 Qd4+ 5. Kb5 Qb4 mate. If 3. Kc4 then Be6+ forces mate. If 3. Kc3 then Qf6+ forces mate.	_____	5B0054 I don't recommend cxb4 although it might win but it requires black to retreat his king to stop the pawn on c4. Much more to the point is 1. ... h3! (or d3!) and the pawn will queen with check. If 2. Kg3 d3! 3. Kf3 h2 4. Kg2 d2 queens on move 5.
5B0055 If white can play g6 here he wins, so to prevent that play 1. ... hxg5 2. hxg5 g6! locks out the white king. If then 3. fxe6 fxe6 4. g3+ Kc5 (also interesting is Kc3) 5. Kf4 (He has run out of delaying moves) Kd5 wins the pawn and the game.	_____	5B0056 the position looks difficult for Black. But he can do well with 1. ... Rd2! and now the best line is 2. Qxd2 Rxd2 3. Bxb7 cxd5 and it looks like white has two pieces hanging, but he can play 4. Nf3! so now Rxe2 5. Bxa6 Ra2! and Black wins a pawn and has the better game.
5B0057 [solution]	_____	5B0058 [solution]      [Next]
5B0057 Although black can win with 1. Rf2+ Rxf2 2. Qxf2+ and 3. Qxf6 and 4. Rg8, Black might as well play for mate because of the exposure of the White king. There may be more than one way to get mate, but it probably has to start with 1. ... Qd2+ 2. Ke4 (Not 2. Kf3 Qe2+ 3. Kf4 Rg4 mate.) 2. ... Qe2+ 3. Kd4 Qd3+ 4. Ke5 Qe3+ 5. Kd6 Qc5 mate.	_____	5B0058 1. ... Nxe4 wins at least a pawn. If 2. Nxe4 Nxd4 gets the piece back. If then 3. c3 Nxe2+ etc. But this can get trickier than that. If 2. Nf5 Nxc3! and now 3. Bxb6 Nxd1 4. Nxg7 axb6 5. Rxd1 Kxg7 wins. If instead 3. bxc3 Qa5 4. Nxg7 white has won a pawn and can win another with 4. ... Qxc3 because the knight on g7 has nowhere to hide.
