Its a totally different argument. With KK preflop there is a very small chance you are behind.

If you hold 22 on a TTJ board there is a huge chance you are behind.

In Omaha (especially 8 or better) where the nut hand is often held by 2 players you are foolish to play for stacks on a 2 flush flop board with the nut straight and no set and no flush draw when there is heavy betting. Your opponent is virtually telling you the best you are getting is half the pot.


In Texas holdem it is rare for 2 people to hold the current nuts and people will put alot of chips into the pot without the nuts so it is correct to call in the original example. In omaha people aren't nearly so inclined to bet without the nuts so it is often correct to fold the nuts with no redraws.
