Hello all. I have been playing now for a little over a year. I totally understand that I am a very new player, but I have confidence that I have managed to learn it rather well.

In the past two weeks I am about $200 up total from playing at a local casino at a 2/4 table. Some nights, of course, have been better than others; but all together I seem to be doing ok. Here's a copy of a portion of the hand groups from this site:
Group 5: KJ 77 QJ KT QT JT A7s K9s Q9s T9s J9s
Group 6: 66 55 44 33 22 A5s A6s A4s A3s A2s
Personally, I have a problem playing T,J,Q,or K with a suited 9. At least with K9s and Q9s, you seem to need to much help to make a straight that it isnt worth it, and the chances of making your flush and losing to an A high flush is rather possible. Is this wrong? Should I play more of that second half of Group 5?

The best bit of poker advice I ever read was one of the pros saying "Fold the second you think you lost the hand." This was said in the context of you never have too much invested in the pot to fold at any time and you never, never think "Well, I know you beat me, but I gotta see" then call a bet. It may only be a dollar or two dollars here and there at the 2/4 level, but over the course of several hours it will kill a bankroll.

This has become the centerpiece of my very conservative strategy that has worked pretty good thus far. I know I have a lot to learn about the game, but can anyone suggest some improvements for my young strategy?
