Ok, by now I think I rather should have called.
I tried win the pot right now, but forgot about who I am up against.

Both villains are really loose. They avoid the worst preflop trash, but they don´t know about relative hand values. They don´t misplay their hands purposely but they can´t lay down anything half-decent. So a straight, even the stupid end, may win a lot against, say, two-pair.

However, the straight cards are no clean outs against four cards out there that may be a K.

Anyway, may hand is pretty good, and it doesn´t feel good to have such a draw and wait silently for the cards to come... but w/o good fold equity, it´s the right way to play it, I assume?
