There's really no reason a pot-limit game should have very small pots, and calculating odds is always a valuable skill. I don't know what you're trying to claim here. I assume you're talking about PL omaha 8. But, your statements don't align with my experience.
I also like to play pot-limit games, especially Omaha hi-lo, I play for fun, for the soul, for money, in my opinion, hold'em is more suitable. But you can win a decent amount in pot-limit tournaments, the main thing is to believe in yourself!
La verdad es que juego al pequeño omaha hi / lo, ¡no me llama la atención! Es cierto como dices, los porcentajes y la habilidad influyen mucho !!! Saludos
