PLO50 2nd Set + 2nd nut FD

[Grindaments]

Still new to Omaha but was after a line check. I figure that my Q high flush draw is going to play often enough but at this level and given the PF raise from the SB how much more concerened are we of villan holding Ah? Also, should I be re-raising instead of just calling on the flop? Apologies for not converting but HH converter isn't compatible for BOSS.

I have a headache from reading that HH, as well as one from trying to figure out why you wouldn't raise the flop.

Raise flop. Opponent has almost certainly straight, but you've plenty of outs and some fold equity if he doesn't hold nuts. You're in small trouble if he has nut flush draw to go with the straight, but the stacks are too small to care about this.

If you don't raise your opponent is often folding when you hit.
