AGA scoring for one rank difference?

Post by often »

What is the typical komi for AGA scoring with a one rank difference?

If even it's 7.5, and white passes last which becomes 6.5

But if between a one rank difference, it's typically .5. However, if white passes last doesn't that make it .5 in black's favor? So does that mean it should be 1.5 in a one rank difference game?

It's 0.5 still since you're doing area scoring and the pass stones are meaningless when viewed that way (prisoners are not used).

The pass stones are a way to make counting territory subtracting prisoners working out to the same answer. Give it a try and experiment on a small board. What you're arguing for is a higher komi so that territory scoring (Japanese) would always win, but AGA is not doing that.

its area scoring, as oren said.

By area scoring, different rules treat handicaps differently, as to whether they give White credit for handicap stones. (I do not know the details for AGA rules.)

He was specific about a one rank difference so I sidestepped that since I forgot the answer. :)
