There is little historical data available online on the rule details for side events, as they are not always held, nor always held in the same way. Theoretically it is indeed possible that the designer thought the value of a handicap stone to be 10 points, and decided to give white 3-4 extra komi in even games, but I can't imagine anyone would design a system that way. Herman: I think it is reasonable to make the assumption that the even game handicap is (close to) fair. Isn't there historical data from these side events? if the value is assumed as 10 then jumping from 0.5 to 8.5 + additional handicap stone may as well be linear though systematically 3-4 points off). Tapir: It is not clear that it is a 8 point jump (without making any hidden assumption about the value of the handicap stone being 16 - which is of course indicated by the base komi of 8.5 - you can't say it is not linear. I have no idea what system was used last year, actually, but it is quite likely this one, since Robert Jasiek organized that side event and it is his system. The effect is noticeable in the above stats at the 4 vs 5 rank difference point, where black's chances suddenly jump up. Theoretically, that is an 8 point jump, where each previous step was 2 points. Herman: The broken aspect of the system is the jump from 'even, 0.5' to '2 stones, 8.5' (and from '2 stones, 0.5' to '3 stones, 8.5'. (Maybe a go server can help with data.) But wasn't the very system used last year at the EGC as well, Herman?

The main point should be the 2 point komi per rank difference and 5 ranks per handicap stone which is absurdly low regarding to all other proposals.

Tapir: Well, he said it is for free placement of handicap which is supposed to be more efficient. Herman: What was the reason for choosing this system on the EGC? As already mention above, it is not linear, which means it is broken by design. (the japanese recommendation 5, timhunt 4, jewdan also 5, aga also 5) Tapir: what was the reasoning for a base komi 8.5? (how were results in even games with 8.5 komi?) interestingly all other proposals have higher differences in komi for one stone on 19x19, this model only 2. In conclusion, it looks like these handicaps are too small for a full-handicap amateur tournmanent. Out of 184 handicap games 35 (about 20%) were won by black and 149 by white. Tarvaina ?: The EGC 2010 13x13 tournament was played with the above handicaps (up until 24 grade difference, after which the maximum handicap of 5 stones and 0.5 komi (for white) was used). but the staircase progression is still linear in average? In the above system, the black player gets 2 extra komi every rank, except every fifth rank, where he suddenly gets the equivalent of 8 points.Īxd. At 8 komi, every handicap stone is worth 16 points. Note by Herman on linearity: the standard assumption regarding komi and handicap is that normal komi is worth half a handicap stone.

If Black does not know how to use his handicap (e.g., if he is an ordinary club player rather than well prepared for European championship level), then the system favours White. It works well for championship games in practice though. Theoreticians notice that, according to the standard assumptions of the relation between komi and handicap, this is not linear.

Free placement is significantly stronger in theory but still only very few players know to use that well. Let me suggest some tables nevertheless, where handicap stones can be placed either freely or at the usual fixed patterns, which means 4x4 hoshis also on the 9x9. Whatever the handicap table is, these komi values are essential, unless one lets the players bid for the komi. From that, I have observed that 8.5 komi for 13x13 and 6.5 komi for 9x9 (the latter is also currently used by Japanese professionals) frequently lead to strategically demanding 0.5 games. I have attended the small board tournaments at European Go Congresses since 1993 and watched many of the finals games. (*) In the case of a one stone difference in strength, the weaker player takes black and plays first. People whose ranks differ 20 or more stones, are either unlikely to meet on the board at all or should not engage in a game beyond 9x9, unless for pure teaching purposes, in which case a correct handicap doesn't really matter. Xela: Some people (including myself) feel that putting more than six handicap stones on a 13x13 board (or for that matter, more than four on 9x9 or more than 9 on 19x19) gets a bit silly.ĭieter: Quite so. First column: Strength difference on 19x19 goban, second column, handicap on 13x13 goban, third column, komi to white.ĭifference 13x13 Komi Difference 13x13 KomiĬould someone please explain 6/-3.5 here? I'd rather say 7/5.5 Regarding handicap games, the following table gives one possible way of allocating handicap and komi on 13x13 boards.
