All of these questions have 2 main elements. For extra credit, who knows what they are?
Ok, I haven't read the other answers, but will take my shot (and my licks when my answers are sub-par).

1. A call is +EV if the amount you make when your Expected Value exceed the amount it costs to call when you lose... for example, if you will win 8x the bet you need to win that bet 1 in 7 times to make it profitable... (example, lose .10 bet 7 times = -.70 but win it once into an .80 pot = +.80, over time you will be + 1 bet thus EV is +)

2. A value bet is essentially +EV if you expect to win similar to conditions in 1 above OR if the combination of implied odds and later streets indicate your win will exceed your loss over time.

3. I'm having a hard time with this one and terms, but basically if you can win by forcing villian to fold enough to make #1 true, thus if he folds 1/2 time and you will earn more than 2x the bet, you will be +EV over time.
