Big Pot line check

[Smurph64]

I doubt it too, but playing it passively in this situation is more likely to reduce the size of the pot if I hit my set and also mean that I have to fold on the flop to a miss.

I prefer having some room postflop by 3 betting against these opponents. If it doesn't iso I don't mind.

Having a read on the opponents makes all the difference here. I get a lot more information to work with by 3 betting than I do calling.

Raising for information is not correct but a failed isolation raise is not a bad thing when you get information from it's failure.
