I made a blog post about an interesting recent t-Go game vs Jos Dekker:

a-big-fight-in-t-go-game

Comments are welcome :)

Woah, how did you get WGo.js to support toroidal go? Did you just add markup for the region and then manually duplicated the stones? Or is there some undocumented variant support?

Also, I’ve made a tool for reviewing t-Go games from little Golem. It’s alpha software and provided on an “as is” basis: link.”

Sorry Malcolm for the typos.

Went through the game, great fighting from both sides indeed. Interesting how the whole-board situation ended up being affected heavily by the toroidiality, despite the almost conspicuously normal initial moves!

Interesting game indeed!

I think if white-48 makes an atari at 49 first, white can win the battle (or at least black has to give up the 4 stones)

(Oh if white-48 at original-game-49, black connects, then white-50 at original-game-50, then black cannot even sacrifice the 4 stones)

Thanks gamesorry, I see what you mean; well spotted! I remember now that I noticed after playing 47 that White cutting at original-game-49 seemed too good for White. If White plays 48 as you suggest then I think Black has to lose at least two cutting stones; it seems good for White. So 48 was a mistake but so was 47 - I probably should have played the “shape” diagonal (kosumi/尖) move of at original-game-50. Then the position is unclear to me, but still seems better than in the variation you suggest.

I'll update the blog post at some point.

apetresc, to get that effect I used quite a bit of my own javascript. My code firsts applies some transformations to the t-Go SGF, calculating which stones are removed at each move, and projecting moves on the t-Go board to the 19x19 board with wraparound and markup to indicate the “edge” of the 11x11 board ;  it then sends the result to WGo.js.

Just for the record, I finally got round to updating the blog post.

I reposted the same game on my blog, but this time with variations - I’ve made some improvements to the software so no it can handle displaying variations.

I’ve also added a feature for “panning” the board.

Re: http://littlegolem.net/jsp/game/game.jsp?gid=1873384&nmove=45 / a-big-fight-in-t-go-game // How would you (Black) have responded if Jos Dekker (White) had played I-10 on move 46?  9-I? If yes, then what if Jos Dekker (White) had played J-10 on move 48?

@Sighris

I wouldn't have played 9-I in answer to I-10; I would have played K8 instead in order to protect both cutting points.

I've added this variation to the blog post.
