gomoku tournament issue
Posted: Mar 14, 2025, 1:47 PM

Hi all.
As you know, gomoku is solved long ago. For now, it's not an issue for a strong renju or gomoku player to win a game being first without opening rules applied. It's like 35 or 37 moves needed, not a lot (18th move on this server). There is a lot of players in the world who are able to win 95%+ of games playing first.

The problem is, when two such players meet in the tournament, they will play infinitely.

As to me, I never play surewin openings here. But most of players here does. And if I see a surewin played vs me in the tournament, maybe I will play surewin too. And eventually we will have an infinite gomoku tournament =(

Same in pente. Still remember the tournament i won took 1.5 years to finish, and the finals took 9 sets before karlw finally made a mistake.

Do you have surewin memorised or do you work it out from first principles each time?

When you reach certain playing level, you don't need to memorize such variants, you understand them since in most variants the attack is pretty obvious. I think all gomoku players with rating 2300+ ( https://gomokurating.renju.net/rating_all.html ) as well as all renju players with rating 2300+ ( https://rating.renju.net/rating_all.html ) will hit 95% winrate easily.

Also I've written a book on renju opening theory quite a while ago, so I do know/memorized a lot as well. But it is not about surewins mostly but about playable, equal variants.

Hi Owen.
When I first played against you, I didn't know much about the game or surewin advantage. Maybe some of your opponents don't know either. I'm sure those that join a tournament would, but casual players maybe not.
I'm interested in reading your book. I'm sure others here also would love to, too.
How can I get a copy or link

I guess I’m not sure why you would still play if you know you are going to win. To me, that seems to take the fun out of playing and prevents someone like me from challenging someone like you. I am never going to memorize the sure win openings mostly due to concussions I received in the military. Instead I have to play based on basic strategy.
