 Puzzles from the starting positionCan you make up a game that goes like this?
1. -- -- 2. -- -- 3. -- -- 4. -- -- 5. -- Nxh1# Or another, similar one: 1. -- -- 2. -- -- 3. -- -- 4. -- -- 5. -- -- 6. gxf8=N# You have to make up the moves on the -'s for both games, such that 5... Nxh1 is legal and mates, and in the other puzzle that 6. gxf8=N is legal and mates. EDIT: Puzzle added! Suppose your opponent copies all of your moves. So if you play 1. d4 he plays 1... d5, if you play 1. Nh3 he plays 1... Nh6. Can you find a mate in four for white, assuming black copies all white's moves? There are three possible solutions, but finding one is already very good  So the moves a, b, c, d, with a' being the mirrored move of a, have to be 1. a a' 2. b b' 3. c c' 4. d# Last edited by Phobetor on Thu Jan 31, 2008 5:42 pm, edited 1 time in total. |

Re: Puzzles from the starting position
I didn't know that one yet. I know an other version of 5... Nxh1# which is actually quite different. If you're interested, you can try finding another solution and see if you can find my solution  |

Re: Puzzles from the starting position
Will do. I think I have a vague idea. _________________ FIDE 2118, USCF 2073. |

Re: Puzzles from the starting position I have another suggestion for solving the first problem (perhaps this is what you had in mind...)
Hidden Text Below - [Show it] - [Hide it Again] _________________ 2 plus 2 is 5 for large values of 2 |

Re: Puzzles from the starting position The third (added) puzzle might have the solution like this:
Hidden Text Below - [Show it] - [Hide it Again] _________________ 2 plus 2 is 5 for large values of 2 |
