PLO20
Villain seems like a passive fish so far.
Haven't seen him betting or raising much.
Villain's range should be at least nut-flush draw here, according to my read on him.
Is there are reason to slow play here in order to get the more people into the pot?
Also, someone might raise after I call.
If I raise I may win the hand now which is not the best case I guess, even though calling is risky.
