> I think the common formula is 100 ELO per stone? I expect the per-stone adjustment to depend on the size of the board. Two players might be evenly matched on a 19x19 board when the first gets a 9 stone handicap, but first player would have an easy win on a 9x9 board with the same 9 stone handicap. http://senseis.xmp.net/?HandicapForSmallerBoardSizes suggests that 2 stones on 9x9 would be about right; the author also proposes tweaking the komi. According to http://senseis.xmp.net/?AGAHandicaps, the AGA at the 2004 Congress used no handicap stones on 9x9, adjusting the komi instead. Most human players are much more used to handicap stones, but adjusting the komi is another method of compensating for differences in skill, which is much more fine-grained than handicap stones. ____________________________________________________________________________________ Got a little couch potato?
