The KHL just released the set of rules for the 2010-11 season, and it contains an interesting part, how the KHL will regulate fights. Until the 2009-10 season it just followed the IIHF rules, which had a five minutes major plus game misconduct for any fight. But from the next season it's going to change.
The KHL will give less penalties for fighting, but at the same time they will be stricter. As usual some rules follow the NHL ones, like the rules for the fight during the last five minutes of a match. Probably the KHL managed to preserve the fighting aspect, which can't be erased from the game, without fully allowing it and leaving the fighters unpunished. It's probably a good compromise, but before of any judgement it's better to see how it works out after a few months of play.
