I consider the Badugi limit as one of the best in poker and I think there should be more tournaments because at this limit the player can show all his ability to play.
I'm a fan of Badugi myself and you're right, there are not nearly enough of these games at the sites. Badugi is unlike any normal poker game. The goal is to get the lowest hand with 4 cards where none of the suits match. The best hand would be 4, 3, 2, A with each card a different suit (no straights in Badugi). There's a lot of strategy involved in the betting and discarding cards.
colbec is very simple badugi, you have to have a card of each suit, example: A, 2,3,4 is the biggest game, the smaller the better the card the game. too easy.
I play long time badugi and others draw games and can say, these game are the best to practice and understand how position is important in poker.Position is key of winnings,especially in draw games.
I think its fun and yes I wish more games like that were popular in especially tournament format with antes. I like PlO8 and NL08 wish were more popular.
