At some point about ten years ago, our national go association purchased sets of go stones that each came with a “paper goban”. They also purchased proper go boards, so the paper boards that came with the stones were pretty useless.
So it was easy to get four 19x19 paper boards, and tape them together to get one 37x37 paper board.
We played a few games. 37x37 is huge and it was obvious that we had no clue about whole-board strategy. Everything felt small and local. I can build a 10x10 or even 16x16 moyo somewhere on the board. My opponent will not invade, but instead build their own moyo somewhere else. Invading their moyo seems too small, consolidating my moyo into territory seems too small, so I’ll build my second moyo elsewhere. And so on. The game takes forever, and during all the “opening”, there is barely any confrontation, because tenuki always seems more profitable than answering locally. There is so much space everywhere, why would I play in a region where there are already stones?
Good questions and observations. I’m playing a few 37x37 games on the Little Golem Game Server (see my previous/ above replies) but have only completely finished one, so I can not answer your questions with any confidence or authority, but you asked:
Maybe it is a bigger move to play elsewhere, but MAYBE attacking the opponent’s moyo is bigger than building up a moyo of your own, AND this would be likely if a move could BOTH expand one’s own moyo and reduce the opponent’s moyo.
Using magic, I have created this magnificent beast of a 49x49 game, as proof of concept:
Game information says that it is ranked, somehow. So, it is certainly possible for the server to create the game.
However, there is a catch: You cannot place a stone anywhere beyond column 25. It would seem that the inner workings of the server are intrinsically tied with the coordinate system. It has no problem with rows because those are just numbers, but it does have problems with columns because they seem to be hardcoded from A to Z (minus the “i”).
In the series 9x9, 13x13, 19x19, each has roughly twice as many intersections as the last. The next size up is 27x27. Here is a Japanese woodcut print of an actual 27x27 board, from around the 19th century. Note that the star points are on the 5th lines.
Yes, check out the source code, and improve it. Or put in a fix request. It seems to be written in Node.js. I would go with double letters after Z (Y, Z, AA, AB, AC, …) but you could get up to 50 by using single lower-case letters after Z (Y, Z, a, b, c, …) The letter coordinates skip over “I” as too similar to “1”. Or you could use the style shown on yebellz 49x49 board above: A up to Z, followed by 24 down to 1, in both the X and Y dimensions.
