Most difficult form of poker?

I am writing a research paper for a college course on "What is the most difficult form of poker to play?"

That is, which form of poker requires the player to make the toughest decisions?

As an overall poker enthusiast who enjoys playing all the games, I think it's pot-limit omaha hi-low. Anyone agree?

Discuss.

Indian poker.

The toughest game. Period.

Chinese poker, probably.

Massapequa Stud/8 with all tens in the deck removed.

Never heard of it.

By "most difficult" I also mean in which game would an amatuer get absolutely destroyed by a skilled player?

For example, in a heads up no-limit hold'em freezout with not-too-deep stacks, an idiot could beat Phil Ivey probably 25-30% of the time just by going all-in pre-flop every hand.

7-Card No-Peek.

And it's not even close.

I mean a popular game that's spread in most online places. Not some rare variation please.

Well you should've said that. Anyway paradise spreads Massapequa.

Yes, sorry for not clearing that up earlier.

Among the major games.
