The first part cooks: 1.e4 (or e4 or d3) d5 2.d3 dxe4 3.Kd2 e4xd3 4.Kc3 dxc2 5.Kc/b4 cxd1Q 6.Kb5 Q8d7+. |

Yes, but I don't see how white can play 13.Red5# in this line. |

Sorry, Alex, my confusion! Your problem is of the type that there are several ways to the first move, but the subsequent play excludes all others except one (I had a similar one with long notation : Find the 4 games that are identical up to the move 6.Ka5xRa4 and finishing with: a) 9.Nd4xNe2, b) 9... Be2xRg4, c) 10.Rf3xRf1 and d) 10... Qe1xRe7; this can be found in post 11 in this tread). Your problem stands good chances of being correct; if that turns out to be the case, then it is a very good achievement! |

Alex, just a quick note to let you know that I couldn't cook your 13.Rexd5# problem. Well done! |

There are some new achievments:
Find a unique game with moves
a) 7.Ka3# Stuart Rachels, 2015.
b) 7...Kxb7# Alex Fishbein, 2016.
Both C+ by François Labelle. The second one is pretty hard, I can't solve it. |

7...Kxb7# (!)
Maybe capturing af queen arriving from d5? But how... |

It is really unclear how this could be solved.
Does anybody have an idea where the wK is being mated? |

Well, a4? At least I manage 8 moves with Kc6xQb7#. |

8...Kxb7# with wK (at least) on a5/c3/e5, even with a wasted white or black (half)move. There's even hs#8 with 8...Kxb7#. But in 7.0 moves? |

Yes! After a few days I find the solution! |
|
(71) Posted by Borislav Gadjanski [Saturday, May 14, 2016 17:42] |
The game is a beautiful and unexpected.
7... KxQb7 is wrong idea. |
|

But where is the king being mated? |

WKing plays only two moves!
Kc3!! |

Thank you for helping !
A very nice problem.
It reminds a problem by Nenad Petrovic :
A game began with 1.e4 and finished with 5...SxR#
Find the moves. However, it is much simpler and less good than this one ! |

Knowing that wK plays only 2 moves to c3 makes it easier, of course. The dualistic play with mate in 8th move (starting with 1.e4) should "simply" be shortened for one W&B move and there's the unique sequence. Amazing mobilization of black force. |

Probably the most difficult of this type of problems. It is impressive that the solution is unique. Knowing the final position of the white King was a huge help. Very good! |

So... how about giving the moves. :) |
|
(78) Posted by Nikola Predrag [Sunday, May 15, 2016 16:18] |
Before only 2 wK's moves to c3 were mentioned, some possibilities in 8 moves had looked as promising, e.g.
1.e4 d5 2.exd5 c6 3.dxc6 Be6 4.cxb7 Sa6 5.Ke2 Kd7 6.Kd3 Kc6+ 7.Kc3 Rc8 8.Se2 Kxb7#
A shorter game to the same mate should start with 1.d4 and show another way of removing black d-Pawn :-) |

I had given up, but with all the hints I finally solved it. Great problem, and surprisingly difficult to solve. |

Only when we have solved, we understand the link with the problem quoted by ichai saturday (1 e4 and 5...SxR#). By the way, this last problem seems older than Nenad Petrović : I have "J. Peacock, 1939". |
