WHAT THE FU..? Strange Chess Rules?!?

Welcome to "Me Vs. Amiga-(BattleChess Level 3)"
It is the computer's turn... computer plays blue...
(i clearly thought that i was going to win this game:)... but then...)

BEFORE:
http://homepages.compuserve.de/DennisTapier/allegroforum/BEFORE.PNG

AFTER:
http://homepages.compuserve.de/DennisTapier/allegroforum/AFTER.PNG

I almost fell off my chair, not believing my eyes, screaming "WHAT THE FUC#!">:(.
I do not understand why that move was legal...
What strange kind of voodoo-magic-master-trick-geek-chess-rule does allow a pawn to slay like that???

En passent:

|--|--|--|--|--|--|
|  |  |  |  |  |  |
|--|--|--|--|--|--|
|  |  |E1|Y2|  |  |
|--|--|--|--|--|--|
|  |  |  |E2|  |  |
|--|--|--|--|--|--|
|  |  |  |Y1|  |  |
|--|--|--|--|--|--|

If you make two-step move with your pawn (Y1 to Y2), your opponent can pretend that you made just one step and capture your pawn (E1 to E2).

This move is totally legal. It's called "prendre en passant" in french ( sorry, I didn't look up for the english yet ).
The computer had the right to do it because you moved your pawn ( the one who was killed ) by two squares the move immediately before. Here is an explanation of what happened : http://www.paginus.com/lesechecs/e.html#enpassant

[EDIT] Beaten >:( ( that's what you get when you write too long a post ;D )

Same. Just as saying j'adoube if you touch a piece without intending to move it.

About the position itself... I think I'd rather have black, even without the en-passant, e4-e3 looks like it's enough to counter the thread on the king's side and then you're a rook down...

You learn something every day eh?

I believe the pawn two-step was an addition to the rules, to speed up the opening phase of chess games. I guess somebody complained that was not fair, because that would allow you to avoid getting slayed just like you were trying to do right here. So that is why the en passant rule was introduced.

Posting this just to make sure you know about the castling move (another url, check the special moves), so you don't have to come back here when the computer pulls that one at you. :)

Hmm... that's a new one for me, but our house rules only permitted a double-space move for a pawn once in any game (which normally occured during the first two turns), so that explains why the situation never came up ;)

Neat.

How? Even if computer didn't capture your pawn but just moved it one square down you would have been in trouble. Also I don't think you were going to win with your opponent having two rooks on the last row. :)

A pawn can move two squares only from it's starting position, but it's counted for every pawn separately. :)

Well, it's obvious what happend here.
The computer's pawn threatend the area you were passing through. He must have scored a critical hit with his attack of opportunity - or, if the compuetr's pawn is an assasin and had enough time to study you, it might simply have been his deadly strike.

You can avoid this by letting your cleric (or druid) buff you before combat. He should also have a cure spell ready in case the HP of one of your party members are dropping below 0.

Great let's play it through(Starting with the BEFORE situation). You're blue and you just moved e4-e3.
Now its my turn: I move my pawn f4-f5.
Your turn.;)

Corelian: Yep thanks, though i already knew the castling.:)

Not much trouble as i see it. (see my response to evert)

Good news: I just played another game on the same level(lasted about 4 hours(most of the time the computer was idle thinking) and i won.Yeah!:D

Ugh, I do hate coordenates. Why people can't use ye olde P5A (that may be P5B, since alfil in spanish is bishop in english)?

Rey?
To make sure we're talking the same coordinates:

8   x   x   x   x
7 x   x   x   x  
6   x   x   x   x
5 x   x   x   x          
4   x   x   x   x       
3 x   x   x   x      
2   x   x   x   x
1 x   x   x   x  
  a b c d e f g h

Yeah, but I am playing chess, not naval battles :P There is another system, where you say [piece][target], P5B you are saying you are moving a pawn 5 squares from the Bishop square. Of course, you may be too young to have ever heard of it :P

That wouldn't happen if Dennis gave all of his pawns Spring Attack.

I recall hearing people say "Pawn to Rook 4" or similar.

RB: I know what are you talking about :) I think here in South America most people still use that system (or at least here in Uruguay)

Ok, e3xd2+

I fail to see your point, but we'll see, won't we?

EDIT

Quote:

Because algebraic notion is superior and easier? Anyway, he played PKB5 (Pawn to King's Bishop 5) and I played PQ7: (Pawn takes Queen's seventh).

I take it that 'x' means that you've slain my bishop with your pawn and the '+' means check... Hm... Ok
e1xd2 (slay your pawn with my king)

To that old notion: I don't get it.(Possibly someone could link to somewhere it is explained?)

[edit]
You can take your time with your next move... i'll be back in about 16 hours.
Now that i've set up the current situation on a real chess board next to my monitor, i'm not so sure to win anymore, that is, if i continue to play against myself, black always wins... but well, maybe you'll make a silly mistake:P.

I'll be gone on sunday, so it's best to finish before then. On the other hand... I think I've made my point before that time.

Unlikely, unless I have less than a minute to complete the game. ;)

Main thing I hate about the navy battle coordenates is that you cannot see at a first glimpse if you took a piece or not. With the old notation, you can easily see what is happening with the x, +, ++, !, !!, ?, ??, 0-0, 0-0-0, ap and all those shortcuts. Do this system also use them?

(Edited: This is strange, now I read it is done this way, though everytime I read in the newspaper down here they don't even use the x to signal a capture, directly the pieces positions, like f5-f4, e4-f4).

Oh, and you are right Evert, I got the notation mixed when translating them from spanish (I thought I had to modify the order).

Quote:

PKB5

Since there is only pawn in a bishop line, you could have ommited the K to make it PB5. It is still strange to see a B there, though.

(Edited: See Descriptive chess notation for an explanation of how to use it).

Could be worse, I wrote a chess program long ago when I was first learning C, it was never completed but somehow after some moves the AI Queen would go berserk and disappear taking a few pieces with her, nice self destructing queen... I'm pretty sure it wasn't a legal move ;D

I couldn't resist coming back early.
(I could delay the end of the game a little if i wanted: h5-f3;D)
But i won't. I surrender. You win!:)

Now i'm going to read those instruction on the old notion, thanks Rey.
