[Silent A]

I agree with the gist of your post, but here are some thoughts on where I deviate from your method (the following is based on my experience at full table PLO at PokerStars):

1) Pre-flop tightness. The key, I believe, it to be significantly tighter than your opponents. There's no need to drop all the way down to 20-25%, so long as you recognize when you're playing with a borderline hand. I also disagree with your advice about not playing A567s. I would argue that just about any suited ace with some kind of straight potential (even if it's marginal) is a solid money earner in position assuming you can limp (or call a mini-raise).

2) Something you didn't specifically mention: buyin for the maximum everytime. Your opponents will make some gargantuan errors so you need to take full advantage. This is particularily true at the nano-levels like 0.01/0.02 on stars where you can buyin for up to 250BB ($5).

3) Bluff sparingly, but semi-bluff in position at almost every opportunity. Here is one of my favourite plays at these levels. It works like a charm at PLO25 (not as well at lower levels because players are too dumb, and not at higher levels because players are too smart):

You flop the nut-flush draw on a board like Q76. It's checked to you and you bet pot from the button. Lots of nice things can now happen. Obviously, everyone will often just fold. More often though 1 or 2 people will call with straight draws and/or a weaker flush draw. If the board pairs on the turn, a half-pot bet will win you the pot almost all the time (the one exception being if it gives your opponent trips). If you hit your flush you will often get significant action from lower flushes and even made straights. If the turn comes a blank you just play poker. The beauty is that if they hit their straight they will often check to you or bet small (like 1/3 pot or less).

This play is one of the main reasons I like playing suited aces in position so much.

4) Second barrel with the naked A bluff doesn't work very often. Most of the time, this bluff will either work immediately or never. At these levels people who are willing to call pot bets on a flush board without the nuts are ridiculously stubborn. Use this to your advantage when you actually have the nuts.

5) If you flop the nut straight with redraws, play it as agressively as possible against most opponents. Most of the time they will have no redraws whatsoever.

6) The size of your opponents bets usually indicate exactly how strong their hand is.
