The 13 x 13 thread

This is a thread for anything 13 x 13. :slight_smile: Post your games, strategies and general thoughts here.

13 x 13 is, I feel, the least played out of the three most common sizes. (Anyone got stats?) People seem to like the extremes of 9 x 9 and 19 x 19, one of them very tactic-heavy, the other very strategy-heavy (?). I’ve heard people call 13 x 13 “boring” in comparison.

I often feel that 13 x 13 is the most difficult board size out of the three for me. It requires good whole-board judgment. Many local moves I play seem to have immediate unintended side effects globally.

Personally I avoid 4-4 openings since 3-3 invasions feel big, so I often play dual 3-4 with either colour. Approaches on the widest side feel dangerous because a responding pincer threatens both your approach and your own corner.

How do people feel about tengen as an opening move (for either colour)?

Handicap stones feel much better placed on 4-4 stones than on 3-3 stones IMO.

Here’s two old posts I’ve found with 13 x 13 meta recommendations:

I don’t really like 13x13 and have played only a few games IRL at that size. However, I hate to see your worthy and interesting topic idea get no responses, so…I have heard it said, and I agree that influence is much less important in 13x13 because the center is so much smaller. I know some people disagree with this, but if there are fewer points in the center, moyos can’t play as big a role I would think. Consequently, opening with tengen is probably even worse than in 19x19. The reason I don’t like playing 13x13 is that I find it hard enough to learn and improve at 19x19 and don’t want to get mixed up or used to a different spatial relationship between the corners. It’s fine, of course, as a stepping stone to 19x19, so players can get used to the big board. At the same time, if players enjoy it—just as many enjoy 9x9—then that’s great; I certainly don’t mean to be a killjoy.

I especially liked your comment about approaches in 13x13, which was a new idea to me.

I found this 13 x 13 pro game review by Nick Sibicky very interesting and helpful. He discusses some general aspects of the 13 x 13 board. https://youtu.be/lfARuBqYgqI

13x13 thread \o/

IDK what I think about 13. Starting out, showing friends the game at brewery it was all we would play. I dislike 9x9 and no one else was particularly into it… but everyone refused handi and didn’t like retiring so 13 helped minimize the portion of game spend waiting for a resignation :stuck_out_tongue:

I quite like that it is small and fast enough that it feels like only a slightly larger commitment then 9x9, but still at least has a handful of normal opening moves even if that does start going to hell by move 10… You at least reserve corners and make bases and fight over territory.

Definitely wish there was more love for 13 and more players who would jump to in en route to 19x19 or for quick games. 9x9 to 19x19 is quite a shock, 13 is a good step between.

It likely has at least something to do with availability of opponents, so until we see something spark a major change it will likely remain the bastard go :frowning:

13 x 13 is popular on GoQuest (along with 9 x 9) with hundreds of games being played live everyday. http://wars.fm/go13
There are some very strong players including spaceman who is Ohashi Hirofumi (6p) and has recently been commenting some of his 13 x 13 games on youtube (in Japanese) - I can’t understand what he says but I still find these short videos fun to watch: https://www.youtube.com/channel/UCFTkcMid0UOYU34bJnWppoQ

I have played more 13x13 IRL in the past year and have grown much fonder of the game. As you say, its speed compared to 19x19 is attractive.
