Playing the 2nd Nuts in omaha

The second nut flush or straight has to be one of the hardest hands in PL omaha to play well as it is so difficult to find out cheaply whether you are ahead or not. Often (especially with the flush) people will strongly bet the blockers.

The best example of this is when you hit the K high flush and someone else at the table has the Ace but no flush. A strong player can bluff this situation extremely effectively leaving you with a decision for all your chips knowing that you may well be drawing dead. If you bet he pot with the K flush and then are raised how do you decide what to do? It's a huge decision as if they have what they are representing you lose your whole stack, however they may just have the Ace and be representing the nut flush.

So how do you know which it is? Simple answer is that you don't, you have an idea based on the situation and player but they may well play both hands in the same fashion giving you no information.

I never know how to play these as although you do have a fantastic hand if any strong resistance is shown it is quite likely to be beaten - I usually play these hands extremely passively as to be honest they scare me as I don't know how to play them. By doing this however you allow aggressive players to steal and draws to the boat to hit. Obviously the ideal is somewhere in the middle of these two approaches - lets call it cautious aggression. You will reraise but be ready to stop betting if they stay in the pot.

Situations like A high flush vs K high flush can be extremely expensive and a misread cost you your entire stack. The second nuts is the one hand in omaha which I feel I struggle with - I manage to play it profitably BUT I often feel that I have minimised my winning on many pots because I can't fully commit.

I'd be interested in any advice anyone has on hands like this as it's an area I can definitely improve upon.
