This has been $.02/$05, $.05/$.10, $.10/$.20 and $.25/$.50 6 handed. Have also tried out $.50/$1, but haven't played enough hands to see if I'll be successful on that level, although I'm up so far. Have pot raised with any hand in any position if noone's called or raised before me. If folded around to me in SB, I raise 4BB.
If someone 3-bets me I fold, unless I have a premium hand. I don't defend any blinds unless I have a premium hand, and I don't try to be creative with any marginal hands.
I never flat call to see if I can get more out of the other player post flop. If someone raises before me and I hold a hand like AJ, I fold, unless I think they're trying to steal the blinds.
If up against one person and I believe I'm in front on the flop, I bet, if not I check and fold if facing a big bet. If up against more than one player post flop, I only bet out if I have the nuts or near nuts.

The theory behind this tactic is simple; play the players, not the cards. Most players playing this kind of poker will play very tight as they will wait until they have a good hand before betting, as the next hand is always just a click away. If you're up against a lot of tight players, you have a good opportunity to steal blinds, just like if you're up against a lot of loose players, you should tighten up your game and pick your spots carefully.
Also, playing 6 handed makes it less likely that your opponents have a hand they will play. I wouldn't recommend playing this style on a full ring table.
This has been on the iPoker network, where players in general are believed to be softer, and often at night there aren't that many players playing, so youmight end up four handed.
