Comments

The best Omaha hands are less bigger favorites against an average hand compared to Texas Hold'em.

In Texas hold'em, is common knowledge that A-A is very big favorite against all other hands. In Omaha, A-A as a part of a hand is far from that strong. In general, a A-A-x-x versus a Omaha random hand is 70-30 in average.

Hands versus draws

A typical feature of Omaha Hi is a set against a drawing hand. The made hand will not be a very big favorite (sometimes even an underdog), so the recommended strategy is to play fast and bet/raise the pot in these situations.
