I fold 22-66 in EP and I still maintain a loose PF range.

I am not a fan of seeing a cheap flop with these hands. I like to raise PF and build a pot because if I do hit my set, I would like a lot of money going into the middle, and that's much easier if the pot is 10BBs on the flop and not 3BBs.

10BB pot
bet 7BBs on flop
bet 20BBs on turn
shove river

3BB pot
bet 3BB on flop
bet 7BB on turn
bet 15BB on river
