Why receive achievements only for winning? Draw in knight fight is quite rare (not by mutual agreement or in match on 2 games). Or some underdog's achievements - lose dice poker by 5 pts and less, lose knightfight by 3 and less pts, e.t.c.

joshi tm: no resigning? Playing to bitter end is meaningless. And be forced to play until end because someone want obtain achievement? NEVER. There shouldnt be any achievements wich will lead to delaying game just because attempt to achieve achievement.
