how to adjust to varying preflop overbets

I was thinking about poker this morning away from the table so I don't have a concrete example to hand. With no reads on an opponent (which is often the case at 2nl when someone joins the table and is only about for a short number of hands) how should you let overbets affect your play?

e.g. someone raises 4bb/5bb or 4bb+bb per limper I treat this as a standard raise, if someone raised huge say 10bb I treat this as a sign that they're very strong unless I have a better read... But how about if someone open raises, .12,.14,.16? or 6,7,8 bb's at 2nl respectively? At what point should I start treating these raises as repping a very strong hand at the very micro stakes and adjust my 3bet / calling ranges accordingly? And at what point does it become unprofitable even given the fact that you think they are raising this over amount as their standard raise size, to play conventionally against them with a 100bb stack.

Thanks in advance for your thoughts.

just treat it as a normal raise with worse pot odds
so call up to say 6x with a pp to flop a set, I use a 15x rule because more than half of the time people will have overcards that will also need to hit for you to stack them
since your pot odds are bad (since he's overbetting pot) I don't think you should be calling a huge raise pf with a hand like AQo since you will be required to stack off if you hit

the rule is that once you put in 1/10 of your stack into the pot you should either make a commitment to the pot or fold

so just 3b hands like AK and QQ+
it's usually EV- to call an overbet on any street (unless it's the river) since if you have a great hand it's better to raise and if you have a meh hand it's better to fold because you're getting terrible pot odds

there's a reason why we choose around 3~4 bb raises preflop. We do it because it's better than doing 6~10 bbs. What mistakes are we not making that larger raisers are making? Or, are we being fooled?!

in NL2 6BB is probably better though because people will still make the mistake by calling our raises with dominated hands

kind of like when people call 30x preflop in live games

Some mainly do it with hands that have value but that they would prefer to not play postflop with like 77-JJ A10-AQ. If it was not their standard raise I'm 3 betting QQ+ AK and getting it in.

nice reading your responses guys. A500 this is what I was trying to get at in my question but couldn't articulate it. Thinking about your question I think I'm now clearer on what i was asking in the first place LDO

Is this about effective stacks? are the hands we should be raising PF only worth about 8/9% of our stack initially in relationship to what we're getting paid when we make them? by betting more than the standard, say 8bbs the villian is now putting 16% of a 100bb stack into the hand instead of 8/9% and this affects their IO.

Is this heading in the right direction or am I going at it from completely the wrong angle?! =)
