no limit is more interesting I think.
a) more skill involved
b) popularity, most of the tourney and cash game are no limit
c) more values
I think the most important of thing of no limit holdem is the strength of your opponent card, if you can correctly read the strength of your opponet card, u can make much more money than just playing your card. (even @@ hand)
But in limit holdem, the easy option for them is CALL. You cannot reli bluff them out of their hand. Don;t you agree?
