re: Ed Miller vs. Piers
My initial pre-flop selection strategy for SB was to play just about any two suited and other weak draws, especially in a multiway pot, as guided in SSHE. But as I started to do this, I realized that there doesn't seem to be much as much value in this, because of the positional disadvantage postflop - so if you miss the flop, you sit there like a gimp and check/fold, usually. Which means that it really is just a wasted bet - and I'm sure those wasted bets add up over time. So I've steered myself more into the Piers school of thought on this one - although I might do some experimentation and try and play some of the slightly-stronger draws, like a modest suited ace (A7s and up), in multiway pots with at least 3 limpers.
I suppose on tables with consistently weak-loose pre-flop action (say, 6+ limpers), you'd be pretty stupid to not toss in that extra 0.25 BB - but even then, I'm not sure I like Miller's "any two" rule. But hey, that's just me...
