I used to have a cheat-sheet on my desk that I'd refer to as a reminder of what hands to call with, which to raise with, and which to re-raise with, from early, middle, late, and blind positions. I don't know what happened to it, and I'd forgotten I used to have it, until I created a new one (again, based on Small Stakes), and used it on Friday.
It felt good; I wasn't waiting on flops and crossing my fingers for a check-around any more. I ended up +$9.55, but more significantly, I played three simultaneous tables, and ended up ahead at all of them.
Has my flat/downward trend started to improve? Maybe. Time will tell.
