Right then, Alice chess.   :)   There's a slight difference in notation: Add either /A or /B to the end depending on which board the piece started on.   Like if you wanted to lead by moving the king's pawn two spaces forward, that'd be 1. e4/A.  If Black replies 1. ... d5/A, you could play exd5/B, e5/B, etc.

Xylorta's got first crack at me; if you still feel like a round of Alice chess, go ahead and pick a side.   :)   Otherwise, anybody else interested in trying this is welcome.

I, Taylor, shall choose Black.
... It's my favourite color ^_^

Alice Chess is about pieces teleporting from one board to another and vice versa.

I suggest you'd read this, as it contains the rules of the game: https://en.wikipedia.org/wiki/Alice_chess (https://en.wikipedia.org/wiki/Alice_chess)

Hah.  Mine too!   :)

It'd be a bit silly of us to start a game without knowing the rules, wouldn't it?   :D   

A quick hint on early checkmates: One tricky thing about Alice chess is that getting out of check works rather differently.  If I put you in check on Board A, you can't block the check with pieces on Board A, because whichever piece you use will be transported to Board B after it moves.  For this reason, it's easy to mate early if your opponent moves the queen's pawn and you check the king diagonally with a bishop.

Anyhow.  1. e4/A.

Post by: Dr. Egregious on November 03, 2013, 06:00:31 pm
Ah, you've made the first move that would've been impossible in standard chess.  Cool!  :)

And at first I thought you'd protected the e5 pawn, but protection works a bit differently in Alice Chess it seems, since capturing is now a hit-and-run deal. 

 :D   A piece on Board A can guard friendly pieces on Board B, but capture enemy pieces on Board A.

That's going to take some getting used to...I thought for a moment that I'd left you the c3 knight, but actually I got lucky; if you take it, your queen will show up on Board A where I could recapture with three different pieces.

On the other hand...in standard chess, I'd follow up with 5. Qxg7 and 6. Qxh8, crippling you; that won't work here, because taking the g7 pawn will ship my queen back over to Board B.  So it's working in your favor too.   :)

Post by: Dr. Egregious on November 03, 2013, 10:13:11 pm
And the king just slips away to a fresh board.  :D   Something else that's tricky: Since knights alternate between white and black squares, they're now similar to bishops in that they'll either be white-only on Board A and black-only on Board B, or vice versa.  There's something I'd like to do with my c3 knight, but it will never work because my target square is black on Board A, and that knight is white-only on Board A.  :)

Ah, I can evade by moving my queen parallel to the bishop's line of attack.  :D   I love this variation already; it's so whimsical.

Knight A6/A.

Dear me, another check.  In the words of my favorite player: "if to 'play like a girl' meant anything in chess, it would mean relentless aggression." :D
The results of being locked in a room by one's younger sister and being stuck in said room for a few hours, and then getting in trouble from one's own father, instead of the real culprit, is infuriating.
The relentless, burning fury of a seventeen-year old teenage forum administrator is being unleashed right here, right now. And at several other chess matches.

... As for the different font, I am just pulling a Shane (http://shanescavestory.createaforum.com/chess/an-egregious-introduction/msg10288/#msg10288).




EDIT BY SHANE:
Um. Is it really necessary that you vent your fury on me, Dr. Egregious and Dr. Time?
Sure, your younger sister should be ashamed of herself for both locking you in said room and getting away with it, but instead of venting your anger on everyone else, vent it on something else, like a video game or something.

And please don't retaliate, Taylor.
Otherwise I might faint again and this time end up in hospital or something! D:

... Whatever.

I'll be leaving for now; I've removed my admin abilities.
I am sorry about this, but I believe it's for the best; I don't want accidentally to do something I regret.
When I feel better I will return, and also with my admin abilities.

Sorry about the delay-to-be, by the way.

~ Taylor


ANOTHER EDIT BY THE SAME SHANE AS ALWAYS:
Well, this is going to be interesting.

... I'll see about that. :P
Let the games continue~


Knight to A6/A.

Pawn to B6/A (the teleportation would block B6 on board B, if I'm not mistaken).

If such a move isn't allowed, King to E7.

I'd been meaning to mention that.  So far we've been allowing such moves, but technically they're illegal.  "A move must be legal on the board on which it is played,"; therefore, a move where you escape check by interposing a piece will not be legal if the piece starts on the opposite board from the king, because that move will always leave you in check (prior to teleportation).  This exact reading of the rules is flawed, however; it would allow you to block with a piece on the same board as the king, and then teleport that piece, leaving you in check once again, which would be nonsensical.  So I'd say we should modify the stated rules, as far as escaping from check is concerned.

Rather than "A move must be legal on the board on which it is played.", which is supposed to keep you from giving all of your pieces jumping powers (and actually redundant), we could say "A moved piece must be able to reach its destination square on the board on which it began, the corresponding square on the opposite board must be unoccupied, and the position must be legal after teleportation.

If I'm not mistaken, this is checkmate.

The f7/B knight cannot be captured by any Black piece on Board B.

It is impossible to escape check by interposing when the checking piece is a knight.

The Black king cannot move to e8 because of the black rook (before teleportation), to e7 or c7 because of the d5 white knight (after teleportation), to d7 because of the c6 white bishop (before teleportation), or to c8 because of the black bishop (after teleportation).
