Here are a couple tips for Rush:
1. Steal from the CO and BTN if it's folded to you damn near every chance you get, unless you have stats showing that the blinds are aggressive in defending and you have a terrible hand.
2. To go along with #1. Restealing from the blinds can be very profitable as well. 3Betting light has worked out amazing for me. Especially if you get someone who is min raising, many times they are just checking to see if people have their Check/QuickFold box checked, so when you come over the top of them, they are folding their junk.
3. Use the Quick Fold to your advantage. You're going to make the most money with Rush the more hands you play(given that you know how to play obviously). Sitting around and watching hands play out won't help you much, use the replayer after your session to go through key hands and make notes.
4. Triple barreling light very often will not be profitable in the long run. Many of the hands you will see go to showdown will mostly be higher marginal hands that are likely to beat your junk. Also, at these stakes, 95% of the field don't know the difference between a value bet and a defensive bet, so your bet sizing on the river means nothing(ie. just look at how often you'll see someone make a 2BB bet on the river into a 25BB pot). Don't give many of the players at these stakes credit for being knowledgeable.
I have more, but I'm getting tired, maybe later.
