I've got the entire Roy Rounders 'buy my stuff' e-mail list in my inbox, I still glaze over it time to time, but most of his stuff is very situation specific. Let's say we're in that hand he posted, with the QT, the T9, and the KK. T9s opens with a raise from MP, QT calls from CO, KK's on the button and 3-bets, and we have AA. What is our correct action?
Well, that depends, we only know what our villains have, not anything about them. We don't know what kind of game we're playing (tournament or cash), what stack sizes are, and what player frequencies are. If we call and spike an A the likelihood of us losing plummets to just barely, and on a flop of say, AKT we're really only worried about a Jack to come. Or if the flop comes T-high with no 9, we're up against top pair x2 and a lesser overpair. Regardless of which game I'm playing, if I think I'll get called around I'll raise.
The goal is to win the most money possible, and having a multiway pot is a good way to win a lot of money, however I personally prefer to take drawing hands into multiway pots, in position. Because flushes and straights are bigger than pairs, two-pair, and sets. However I also like taking big pocket pairs into multiway pot, depending on my villains, stack sizes, etc. If I hit big, I can milk them, getting 3:1 on every one of my bets, as opposed to 1:1 headsup. Granted, I'll run into some bad beats from time to time, but it's part of poker, and every bet I make where I'm getting 3:1 on my money as a favorite to win, that is a big pot with a big payday, provided they hit well enough to continue drawing on me. I can fold my hand in a multiway pot when obvious outs come, or at least figure pot
odds, because usually when I'm in a 4 person pot, people aren't betting enough to force out draws. Except regs, that do that... So if I have overpair and figure you for two pair, you might be giving me the correct direct odds to call, let alone implied odds.
A lot of Roy's stuff helped me out when I was still learning, but now in retrospect it seems out-dated and mostly serves as a tool for him to sell his book/programs.
