It's like having 1/2 NLH and the next game is a 5-10. They run 2/2 games (200-700) and the next game is 5-5 (500-2000) which sounds normal but the 5-5 game is actually a 5-5-10 game as everyone straddles and the 2-2 is really small, straddle is 4 but most people including gamblers don't straddle,also no round up for example if pot is 19 you can't bet 20.
