The Sklansky strat for tournies only works in tournies where everyone starts shortstacked and you have pussies in the game who won't go all-in. You would get eaten up in the WSOP, and you will get eaten up in Party and Pokerroom MTT's (for different reasons in both cases).

In tournies, you can't use a simplified strategy unless it's something like the Party SNG's where everyone starts shortstacked. Properly-structured games can't be beaten by simple strategies.
