Should I really trust SNG wizard's advice fold my 66?
why not? SNGwizz calculates a EV situation. If ranges are 100% correct (which is impossible imo) then its a long term +EV fold.
Only reason not to do / ignore wizz is when the increasing blinds catch up with u (this is one thing SNGwizz never accounts for), but I think 200-400 isn't the end of the world yet with the other shorty around.
