1.Re2 checkmate. |

| Jun-30-08 | | achieve: <The king horse of course came from e1 or e3, escaping a check....> Yes, I see it now. It's obviously not my day. Very good second example btw. |

I like the way the king, seemingly completely in the open, is trapped by White's queen. It occurs to me that queens are probably stronger in King Horse Chess than normal chess... |

<SwitchingQuythulg> -- <It occurs to me that queens are probably stronger in King Horse Chess than normal chess...> Absolutely. For one thing, an unsupported queen can deliver mate. <mack> Think you meant 19.g5#. Nice find, though. It seems to me that in this type of position
 click for larger viewthen *any* check will be mate: a Bg2 or Ng3 or Pg2 etc. What kind of material you need to force a king into a corner is a whole nother question ... |

 | | Domdaniel: This might be the quickest win for White:
1.e4 d6
2.Qh5 Nf6
3.Qxf7#
 click for larger viewc7, d6, f6 and g7 are blocked, and ...Kxf7 & ...Kd7 are illegal. But - despite vastly different endings and a new set of opening traps - I suspect that much of a KHC game would be very like a standard (SC) game -- think of all the games that are won or lost without the kings ever having anything to do with it. And I assume that heavy material loss - a queen certainly, a piece probably - would warrant resignation in KHC. Ultimately it depends on the endings, and on what material combinations can force mate. I've got a feeling knights might be more valuable than bishops in KHC because of their king-containment powers - that'd change a few things too. |

 | | Open Defence: I misunderstood the rules, I thought the King moves like the King in standard chess AND like a Knight, BUT the King having a Knight move is nothing new!!
I remember reading somewhere that it was believed in Shatranj, the King had ONE move like a Knight but I cannot find the source now |
|
| Jun-30-08 | | acirce: Hi, <DD>. This kind of chess variants and construction exercises are addictive once you get started. Here I think I found a 2-move mate: 1.Kf3 e6 2.Qe1 Qf6#. Am I missing anything? click for larger view |

 | | Domdaniel: <Deffi> Verily, in this old world we can rarely, if ever, come up with something new ... but we can have some fun reinventing the old stuff. For what it's worth, I think the King's normal move is somehow more fitting, more appropriate to his majesty - a one-square proximity field to deter sneak assassins. But there's a different logic to the KHC King: and with one bound he was free ... much harder to trap, to corner, to localise. ♘ Der Springer |

Jun-30-08
 | | Domdaniel: PS. A king with the normal moves plus knight moves would be almost unmatable ... a true Spanish virgin. |
|
Jun-30-08
 | | Domdaniel: <acirce> Close, but no cigar. I've actually had the same position on my board, by accident. The problem is the white queen on e1 -- if you put it back where it belongs on d1 then the white king has an escape square - back home. I think. This can be very confusing stuff ... |
|
Jun-30-08
 | | Domdaniel: <acirce> A zillion apologies. You *moved* the queen there. Unlike mine, which got there by accident. Hmm. I think you could be right. Ve-rry nice. |
|
Jun-30-08
 | | Domdaniel: <acirce> Actually that's quite beautiful. We've had lines where the king is mated at home, usually via an attack on f2/f7, and lines where he moves twice and gets mated in mid-board -- but the variations where the king moved once seemed fruitless to me, as he could always retreat. You simply blocked the retreat. Exquisite. |
|
| Jun-30-08 | | acirce: Fastest mate by a king move?
Maybe: 1.Kf3 Kf6 2.Kh4 e6 3.f3 Ke8# or, probably aesthetically preferably, Kh5#.  click for larger view click for larger view |
|
| Jun-30-08 | | acirce: (Or 3..Kd5#, of course, but there's no artistic point to that at all, I thought.) |
|
| Jun-30-08 | | acirce: Well, the symmetrical version of this was even better! 1.Kd3 Kd6 2.Kb4 e6 3.d3 Ke8#/Kb5#

 | | Domdaniel: A middlegame blunder to avoid:
 click for larger viewBlack to play
1 ... Bxf3
2.Bxf3?? Nh3#.
 click for larger viewObviously, the Nh3 needs support - here the Qc8 - or else Kxh3 is playable. Also, 2.exf3 is fine - and any earlier move of the e-pawn would have left an escape on e2. What I'm wondering now is whether it's worth it to chop off knights for bishops in the opening - Winawer French, Nimzo-Indian, Exchange Spanish etc - just to be rid of the beasts and their inherent danger. For if Knights *are* worth more than Bishops, most opening theory goes out the window. Allowing such an exchange would be like, say, playing 1.a4 and 2.Ra3 in normal chess to swap rook for bishop. Mind you, somebody did just that against me once, and very nearly won. Not a patzer: a man with a Theory. His was that minor pieces have all the action early on, and rooks come into play later - so depriving me of a bishop leaves me temporarily a piece down, since the lost rook won't count until later. Or something like that. |
