Pot odds shortcut:
if you are playing with 2 cards (eg NLHE) dealt, it'l be 52-5= 47
for PLO it would be 45
divide this by the number of outs you have and you have your pot odds
so 47 possible cards/ number of cards you are drawing to.
eg 47/9 = 5.2 or 5.2:1
correct me if i'm wrong but I think thats it
