Yet another alternative, a la Cho Chikun’s dojo:
There is a longer time limit where each player has a minute to move, and hayago where the players are given just 10 seconds to make a move. There is no time limit, so any given player can play 1 or 10 games in one day. The league also has a rating system. The ratings are based on the players’ winning percentages. There is a handicap, but one that was very different than the orthodox system of allowing the opponent to place the number of stones to the difference in rank. The stronger player gets 10 seconds less in their time for every number difference in rank. There is also a reverse komi rule. 0 komi, —3 komi, —5 komi, and —8 komi.
