Thanks guys. Plenty of good advice here and I appreciate it.

I tried a bit yesterday (350 hands) to play more tight-aggressive and ended up playing 18 and 20% of my hands and with a PFR of 8 and 6 in my two tables

One good observation was that I found it more easy to stay +- 5$ off my starting 50$ stack. That is because I stole more blinds. The bad news was that my strong hands payed maximum 8$ since people scared easily out of the hands, which isn't really bad news after all when I think of it....

Then I lost half my stack on both tables with AQ. One that didn't hit on the flop , I couln't shake one caller off and got called all the way, stepping down with a small river bet to see he held QQ. The other hand I will post on the hand history topic for comments, but basically he hit his flush on the river and I probably should have pushed the turn to try to avoid it, since my read correctly told me I was ahead on the turn. Then I made up my loss throught some very nice flops including a flopped quads and one hand where I stayed in for two reraises preflop with 55 and the flop came 5AA giving me the stack of one guy holding KK and pushing I then quit for the night with a small profit, for the first time in a while.

I will keep posting hands and try to take advice given. Thanks again
