Title: Re: Opening puzzle Post by aaaa on Jan 11th, 2009, 3:02pm Hmm, I added this to the list of puzzles (http://arimaa.com/arimaa/puzzles/list.cgi) (a link of which I, BTW, no longer see on any of the framed pages on the main page), but now I see that one could do one better and simply blockade the elephant in that position, possibly making the puzzle invalid. |

Title: Re: Opening puzzle Post by Fritzlein on Jan 12th, 2009, 7:31am It's a close call whether blockading the elephant is really better than winning a horse, because the blockade has rabbits in front on b6 and d6. Can it really be held? One could get around that difficulty by making is a "capture in two" puzzle rather than a "find the best move". Unfortunately, there appears to be more than one move that forces a horse capture in two moves, because the f6-trap doesn't have to be evacuated on the first move. Thus 4s ef5s Hg5w rc6e cd8s should do the trick as well, or even 4s ef5s Hg5w rc6e he7w. |

Title: Re: Opening puzzle Post by chessandgo on Jan 12th, 2009, 10:16am blockading looks more appealing to me as the threat against the Horse remain. either gold will lose that Horse or let silver consolidate the blockade, which arguably might be worth more than a Horse. |

Title: Re: Opening puzzle Post by camelback on Jan 12th, 2009, 10:16pm In my opinion, resulting blockade is temporary. Any piece in b2, c2 or d2 can go for rescue there is no other advantage other than winning the horse. I may be wrong and others can illuminate me ;D I still prefer he6w instead of rc6e for 4th step in 4s. I guess its just a matter of taste or style :) |

he6w doesn't capture the horse. Gold simply saves it then with Ec7e hd6s Ed7s Ed6e. If you rather meant he7w, then that strikes me as suboptimal, as Gold can capture a rabbit in return. |

Title: Re: Opening puzzle Post by Fritzlein on Jan 13th, 2009, 7:26am In any event, there is more than one move whereby Silver can "gain an advantage of some kind". |

If people think that the puzzle is fundamentally flawed in some way, then I won't oppose it being (heavily) modified or removed altogether. However, one must surely admit that there is something to not trying to give too much away by keeping the question vague to some extent, making the puzzle more challenging and encouraging contemplation and discussion about what achievement might be better (just like we're doing in this thread). |
