I used dive a few times when I started, and at first got nothing but yellows for my efforts.
After a few bookings I started treating diving like I used to with ISS '98, i.e. I only dived when I hit the opposition on the counter cos the ref is so far behind the ball. This is by no means a sure method of winning a penalty, you still get booked more often than not, but I have won 2 penalties from this tactic.
Oh yeah, not even that is failsafe, cos the Iranian keeper bloody kept Timmy Cahill's penalty out on one of those two!!!
