I have been playing Go with my friend (who has a Chess background) for a while now. We started on 19x19 boards but he found it really overwhelming and struggled. He wanted to switch to 9x9 and we have now played several 9x9 games.
These games are just for fun and I don’t think he has much intention of ever playing seriously, so it doesn’t really matter, but I feel like the skils developed playing 9x9 are really not all that applicable to a real game other than just basic life/death, some endgame stuff, etc.
I started on a full sized board, and I ran a successful club where we started beginners off on full sized boards, so I don’t really know how others do it. What do you think about starting beginners off on 9x9? When do you think they should transition to larger boards?
When teaching fundamental classes, we would use 9x9 for those who just got introduced, easier to show life and death and simple local situations (even ladder doesn’t need to run far). And most simple tsumego can fit on 9x9 easy.
But we would switch to 13x13 by the time of beginner’s class (30k) where more concepts can be easier introduced and understand it is not just about fighting but positions, and then 15x15 to more “advanced” starter classes (starting kyu 初級, about tdk 21kyu to 25kyu) for practice which whole board situations would start to make sense. And finally switch to 19x19 when they are about ddk (16k to 20k).
Mind you thought this is for kids’ Go class, not for adults. There is something can be said about teaching adults starting from a larger board, like 13x13. Or just starting from one corner (one quarter) of the 19x19 board, without switching to different boards. And they would get a more intuitive concept of local and whole board positions (like they are playing four 9x9 games on a 19x19, just open toward the center, and you don’t have to win them all to win a game, losing a battle can still win you a war)
