headius: No. The normal is 6.5 in all these sizes if I had understand it right? At the current playing level of most of the people it is not problem, but of course more equal the better. I personally are not so sure which would be right komi.

Salkkuman: Currently on BrainKing, komi is 5.5 for a 19x19 board, 4.5 for a 13x13 board and 3.5 for a 9x9 board.

At the current playing level of most of the people (me included, rating notwithstanding) maybe a komi of 0 (zero) would be nice :)

hexkid: With normal I ment, outside of BK.

Salkkuman: As with so many things in Go, the Sensei's page about Komi is inconclusive

Salkkuman: I would vote for 6.5 for all sizes. For those who think komi should be larger or smaller for 13x13 or 9x9, consider this:

Yes, there are typically fewer points in 9x9 or 13x13...
...but the first move is also that much more important.

I believe most sources agree these two factors balance out so that komi should be the same on small boards.

In actuality, I would prefer a configurable komi, so we could specify it at game start, but I don't know how that would work with the current rating system. Fancier go sites are able to make games rated all the time, regardless of settings tweaks, but BK is limited in that regard. Perhaps only rated for default settings (komi 6.5, no handi)?

3.5 komi in 9x9 = really good for black

tbart: That's why I try to avoid playing white on 13x13 or 9x9 on BK right now; they're heavily weighted toward black. We need komi fixed!

headius: I think making komi a user-selectable value would be nice. Instead of getting handicap stones I could play a game with komi set to, for example, -83.5 :)

hexkid: I'd be all over a user-selectable komi, so long as the standard rated games used correct komi to begin with.
