Do you mean in general or specifically for LO8? This book has already paid itself many times over, and I'm playing microlimit LO8. Anyway, perhaps you could browse through
this topic - I hardly play tourneys these days, so I can't really answer your question.
A study question: how do you guys feel about raising preflop to build the pot (rather than to knock players out to get the button)? For those of you who've read HEFAP, Seven-Card Stud FAP or Sklansky on Poker/Razz: Is the "Concept borrowed from Razz" applicable to LO8?
