I just realized that you had "I don't know what +EV is but thanks anyway" embedded in my quote.
+EV is short for positive expectation value and is a term that, in general, means if you make a move for a certain situation hundreds of times you should expect that move to be either +EV or -EV. In other words you would expect the value of that hand to either have a positive effect on your bankroll or a negative effect.
