One thing I've noticed in the recent videos posted by Phil Gelfond while he is playing mid-stakes online PLO on Bovada is that he is varying his bet size a lot on the flop and turn. When doing this, he often talks about "what can I get to call/fold".

Contrasting this, in his books, Jeff Hwang recommends potting flop and turn pretty much always if you decide to bet. His rationale is basically that people are going to err on the side of calling, it is difficult enough to give people incorrect pot odds on their draws because of the pot limit structure so do your best to give the worst odds possible, your opponent likely has much better draws than you realize even though the board looks very dry, and betting less as a bluff just appears weak and won't work often enough (albeit you might want to appear weak and there are some situations where a small bet of any kind will take down the pot).

Any comments on the merits or drawbacks on either style? At mid-stakes, I tend to agree more with Jeff.
