The question about EV is a great chance to maybe cast some light on this question.
As I understand it, EV has to do with long term outcome rather case by case results, in other words probability of a scenario.
Here is an article about it here on CC: http://www.cardschat.com/poker-odds-expected-value.php
(Mods I know we can't have links but this is to the forum is that okay?)
I like this explanation:
"Expected value is the amount of money a certain play expects to win or lose on average."
I think it is fair to say that as poker players that want to take the game past a recreational novice level it is key look at the long game. So, is it frustrating to have a guy shove every hand in a tourney? Sure a bit but when you look at the numbers of what the villain is doing his math is not as horrible as you might think. The initial shove is of course straight math if he has garbage it is a bad play. However once he has every one stacked at the table (assuming he is not a more skilled player than the rest) it might be the right play for him to eliminate all post flop play and take the skill out of the game. The good news for us as skill players is that we know that we can wait for a hand that can see all five cards face off with him and then force him to play our game once his chips are diminished.
The other silver lining I see here is the info it gives you about other players at the table. Who got frustrated and called light, who thought a baby ace would be a good call, all information you can use later in post flop play after the shover is long gone.
In summary patience and perspective are two things that will prove invaluable as you continue to refine your game.
