A concept I've found indispensible in the very aggressive 5/10 6-max games has been something Andrew Prock termed "The Wall." The strategy, essenitally boils down to this: when you have the initiative, bet; when you do not have the initiative, call."

Now, you won't want to use The Wall in 6-max NLHE games, and you won't want to use it against passive players either. That said, you will absolutely want to use it against maniacs and other LAG-types, plus perhaps unknown players who are exibiting an aggressive style in your first few hands of observing them. With respect to unknowns, there is simply no replacement for pokertracker, a solid HUD program, and data mining, of course, but you'll still see completely unknown players from time to time. My overarching point here is 1.) you should know most of your opponents ahead of time, and 2.) since you're playing 6-max, you'll find a much larger share of very aggressive to maniacaly aggressive players than you would in full ring games.

When would I advocate using the wall? Well, I'm not sure when it is optimal to use this strategy (and surely there are some better situations to use it and some worse), but I do know that when I have a hand that has showdown value, and I'm out of position against a very aggressive player, I frequently use it.

Just as Ed points out the inherent value in betting calling stations to death, there is likely an equal value in calling the raising stations to death. As far as I can tell, in many 6-max games there are as many of the latter type of opponent as there are of the former.

At any rate, I thought I'd throw the thought out there. Could be I'm repeating someone else or just pointing out the obvious... though I didn't really even think about "The Wall" or think deeply about its beautiful simplicity until after about 50K hands at 6-max. I certainly wish I'd been more thoughtful earlier on.
