Hello folks,
I would to like to add that first "raise too big" is not a weak argument.
PLO is a game where the preflop odds are always decent to go to see the flop, because you will hit something on the flop most of the time.
So if the maximum raise is too high, the game lose its momentum.
Also, the Pot Limit system prevent players to go all-in preflop with no action pending which is a huge difference with No Limit.
In PLO, if you have 10 Big Blinds, you need someone to raise before you can move all your chips in. That is part of game strategy.
Anyway, I am glad to see Omaha is getting more popular =)
