Recently I have been playing games where the handicap was wrong. I selected “automatic” for handicaps, so I don’t understand. For example, I played a 9K, whose numerical rating was 1703. I am a 4K. My numerical rating is 1974, My weaker opponent should have received 4 or 5 stones. They only got 2.
How to link. The game info is 10-19; Black was La Day (9K). White was me, Jim Walsh (4K). I won by 77.5 points. Black got 2 handicap stones. Should have gotten 4 or 5.
It looks like the handicap may have been worked out using one of the sub-category rankings though I’m sure I’ve read somewhere that the overall ranking is used for everything.
In my experience this (too few handicap stones) happened only when I played against rather new players (with high deviation).
In your case however this started sometime between October 15, 2018 11:57 AM and October 17, 2018 8:23 AM. There were a lot of updates around this time. I think one of them introduced a change in what the handicap calculator treats as high deviation.
At least handicap is correct for the 2 games I started yesterday. So I think this is no error in the OGS codebase.
I haven’t observed something like that. Contrary in my experience it is always the overall rank. I look the ratings up all time a game starts, therefor I’m pretty sure about that.
Not really, I don’t think so… Handicap is already kind of an approximation, and HC play expects sort of a different playstyle to make use of the extra stones. All in all it should give both players more equal opportunity for a victory, but that does not equal 0,5 difference in end result. Something big can die just as much in an equal game. Does not mean the chance wasn’t there. Maybe it is just more usual to see the game ended by resignation rather than a huge point score.
