Got another straight flush today on a dream board. 

 

How could he fold? He thought I was shoving a K high flush.

Also note the other guys position bet. When I was new to Omaha I thought everyone was only betting when they have it and checking when they dont. Good players sometimes bet draws or even squadush just to take the pot. They play what you dont have depending on the flop and preflop action. Notice their patterns and let them hang themselves the next time you play them.
