In this Spider Linetris game, why is the A column remaining full?

I was thinking that the Line4 players on this site weren't very active, but then I realized I was wrong when I noticed this epic series of games between Jeckelchen and jeckel. Their playing styles have become so refined that they know if they should resign by the second move! Wouldn't this site be more interesting if all players were as busy?

I need 3 more spider line 4 players please!

it's cool as this site. sorry for my new english!

BuilderQ: thanks :)

BuilderQ: I gave two wrong answers in a row . . . a reward for my laziness . . . LOL

Ah, I see Fencer has clarified that more than five win on the Hasami Shogi board.

ColonelCrockett: The rules for Pro Five in Line and Swap Five in Line explicitly note that exactly five must be placed in a row. Hasami Shogi may also follow this restriction, but the rules do not refer to such a situation.

BuilderQ: hmmm . . . I was too lazy to look (LOL) . . . I could have sworn that there was a game on BK that required a specific number of tokens be placed in a row, perhaps Hasami Shogi? I'm still too lazy to look, ;)

ColonelCrockett: According to the rules, no: "The object is to place 5 or more pieces in a solid row..."

BuilderQ: I think Pente requires exactly five in a row though, right?

Hrqls: Yes

does a player win when he places more than 4 pieces in a row ?

BuilderQ: ah i see ... nice

so its up to player 1 (white) to make sure that he wont create a 4 .... as he can see easily he is being mirrored he can play the game all by himself .. and force his opponent to follow his plans (or stop the mirroring)

Hrqls: Yes, but the mirror strategy can prove successful on occasion, even against the best: http://brainking.com/en/ArchivedGame?g=760289&i=52

white is player 1 .. player 2 is the only one who can use the mirror strategy .. but when doing that until the end he will lose as noone will make 4 .. so player 1 wins

this makes the mirror strategy a losing strategy

rod03801: If your offer hasn't been taken yet, go ahead and invite me.

BuilderQ: Thanks for that lol, yeh i didn't really know how to play when i played this one, i think it was my first game or one not long after i started playing it

So, the only way to counter this strategy is to fill up the board with no one winning, which is a win for white? (LOL, I'm sure you know what I'm trying to say)

Would someone be willing to play out a game of anti with me as black, using the mirror image strategy, and show me how you, as white, get out of it? It will make more sense to me if I am actually playing it out. Unrated/Uncounted, if you prefer.

rod03801: An example

rod03801: Aim for a (symmetric) position where there is no line of four on the complete board. Then white wins.

I recently played anti line 4 at another site, and my opponent played using the mirror-image strategy. (I was player 1). I know there MUST be away to get around that, otherwise player 2 would just always win using that strategy.. However, for some reason I spaced it, and had no idea how to counter it, and lost of course. Can someone please remind me how to counter that strategy in anti?

Nugsson: I'd spend more time posting on the stack4 board but I usually hang around the chess boards.

ColonelCrockett: I don't know, I tend to chat occasionally during my games. I don't think anybody uses the discussion boards at IYT. To be honest I'd forgotten they exist.

Nugsson: the stack4 board on IYT is just as dead usually, I guess us "line4" players just don't like to talk much . . .

ColonelCrockett: Two posts in 3 days! Busiest it's been here in months ;)
I'm one of those people who play both here and at IYT.

this board is just buzzing . . . incredibly busy . . . LOL

ColonelCrockett: welcome to BK I'm afraid I don't really know how many people play both sites.

I see alot of the same IDs from IYT. Are there many players who play stack4 on IYT and Line4 here?

nice to know which boards have and havent been solved to

BuilderQ: very nice!

(nice layout, simple and to the point without being boring ... well done :))

I haven't been able to find a truly comprehensive resource for connect four information, so I've decided to start work on my own.
http://fourinarow.50webs.com

that'd certainly make for another intersting game

"Each player receives 16 disks of his own colour and 5 white disks." You would be forced to use wild pieces if the game went on long enough.

BuilderQ: I just took a look, at first it looks like a great idea to add a third color, but if it's an option if a person uses the "wild" or not - I would never use it - I mean why would I want to place a piece that my opponenet can use also.

Anyone heard of CARAMBA 4?

Anyone want to play a game?

thanks ... a dutch site as well .. located (physically) very close to where i did the last phase of my study (1 door away from my room, down the hall ;))

See this site for some solved board sizes: http://www.cwi.nl/~tromp/c4/c4.html

By the looks of your rating and record you have no problem winning with either color. lol . lol

I think black (player 2) definitely has the advantage at this game.

BuilderQ:
Yes, I think I have a program I wrote to play spider line4 (and the other variant where the pieces come in from the edges until they hit another piece). Anyone who wants it can email me:
msmammel at starpower dot net

You would rather play black? I would rather play white. You find playing black easier? I am undefeated still at this (8-0-0) and I always play white.

ah yes i see now :), how dopey am i lol

Otherwise the 2nd person can just keep placing their piece on top of the 1st, and sooner or later, the 1st player will make 4 in a row on the bottom row.

i dislike the fact that you can't place a piece on another persons, seems so strange to me, as to why you wouldn't be allowed

Variant.....

Spider Volcanic Line4 (Kind of like Gold Tokens Blackhole 4 in a row) - except with spider rules.

Start the game out with 1 square (Randomly picked) which is a "volcano" which is unusable for both oppenets. (Maybe even 2 volcanos - but that might be too much for the current board size)

Spider BONUS Line4 - (Kind of like Gold Token's Hotspot 4 in a row) - Except with spider rules.

There is a bonus square randomly put in the board which can be used by both players to make their match. the "Cross dressing" piece which will wear both players colors. :-)

Yes SLAYER, I learnt how to play Spiderline4, & to get to 2700 pts, by beating you, Master! ;) lol! I learnt the game by wanting to know why I got beat by better players...Also I expanded these games with my own ideas & also looked at other peoples ideas too...its all about learning it then expanding it.

Anyway, what is this 'white is always a forced win' rubbish? If you play me, then my black is near always a forced win too! What Im trying to say is that yes, white has the advantage BUT only if you know how to win with white against a certain black, and conversely the player does NOT know how to play a good black! To me black can just take longer to win thats all, and therefore there is no advantage, unless however, I play the very top players!...but I would say out of a lot of very top players Ive played over ther years, there are ONLY about 3 or maybe 4 players who have 'mastered' the white & can always win every time, but sometimes they dont! lol! ;)
