--if you fold more than the rest of the table
--if you tend to enter pots with a raise rather than a limp
--if you tend to be "aggressive" after the flop
Does your average player at 1/2 no how to use that information when constructing ranges? No, but they are still generally processing what they see and applying it in a manner that is logical to them.
For example, I play with one guy who is a spewy fish in a 1/3 game. Not very good, and definitely a big loser over all. He plays a lot of pots and splashes around. he does notice I don't play as many hands as he does, and talks constantly about how tight I am. While he doesn't have a concept of range as we know it, he does put me on "big cards" when I raise. Now this doesn't keep him from calling, because he does so to "crack" my "big hands".
What this means for me is that I can bet any flop with J high or better and he will almost always give me credit for having "it" - with "it" being to him whatever beats most of his hands. I also know that when I get resistance from him (even a flop call) that he is at the top of his range for that board. While that villain may not perceive me as TAG in the way we use the term, how he plays against me definitely does.
So yes, we have an image with (most of) our villains...we just have to understand what it means and how they apply it in their eyes.
Yeah, it's always funny how some peeps call themselves LAG then describe a hand where they play a bad starting hand passively. Invariably they call Villain (who shows up with a reasonable hand) as the "fish"
Not sure what exactly you want to find out, but there are few threads around here that talk about your image. This is more of a chat type question rather than a strat question.
