I'll use a fictional hand as an example. We're playing 6max NLHE, lets say 100nl and have no reads on any of the players, maybe 10 hands of stats but that's it. We've not done much, raised the odd good hand, folded for the most part but we've only been there 10 hands so not anything real to go on.

We get in the bb.

BTN raises to $4, SB calls

The 10 hands we have on the BTN are 20/10/-, and the SB is 40/0/-

Now with good reads on the BTN being a standard TAG I'd 3bet this a fair amount and call sometimes, very rarely folding if I have him as a 20/17/3 type.

With no (or very limited even) reads, how are we proceeding?
Is it really weak to just be folding this early in the session?
Should we if anything be MORE aggressive and 3bet more in this spot?

I think its wise to play at least a few rounds at any given table before starting to make any moves. I think this is best just to acclimated to the feel of the table. I do this even at NL20. So far has worked out well and helps me not feel like I dont know what I am up against.

To answer the general question rather than a specific hand, I assume any unknowns are sharks and play tighter against their raises, even at NL5. (You know how many NL5 sharks you get)

IMO if it's true that you lose less money folding the best hand than you do calling with the worst hand then it's also true that you lose less money overestimating your opponents than you do doing the opposite.
