EV question

[Gar Pike]

Hi, All

I have a question regarding the application of EV, and some confusion of the meaning.

I've read that EV is the result of enumerating all the results of the possible hands, given your holding, expressed as a positive or negative number. So, if I have a +1.3 EV, I should expect, over the long run, to get back $1.30 for each $1 that I bet? or get back $2.30? I think it's $2.30.

On the application side, I know that given a low enough EV you should fold. Does the converse hold true, given a high enough EV you should raise?

What EV is the deciding point for raising?

I know it's not a cookbook answer, but as a guideline for consideration I would like to get your opinions.

Thanks in advance...
