How to narrow down the Range of your opponents

[TheGame232]

Hey guys.

One topic that is allways mentioned in the posts on 2plus2 are Hand ranges. I think if you are able to narrow down the range of your opponets on every pettingstreet you are able to figure their possible hands out.
However it seems to be too much of a thinkingprocess to do that becouse you only have about 10 sec on every street to do that.

Also you have to take in account if your opponents are loose or tight players (wide range vs normal range)and when they are amateurs it is almost impossible to work their hand out becouse they are capable to play everything.

So how do you deal with this importand subject?
