I have the worst luck with higher stakes. At least when I drop $100 in offline games I count it as a social outing and it bothers me less

$40 stacks, $1 is BB.

I have TT in early position. Table is mostly loose and passive (too bad I've been dealt crap all night until this)

I limp in, as does most of the table (not unusual). Someone in late position, who's a bit tighter than most of the table, makes a baby raise of $1. Everybody calls.

Flop is 4 5 8 with a flush draw. What to do, what to do.

I decide that either I have the best hand right now, and need to protect it, or I don't and shouldn't bet. I bet a little over half the pot, 2 callers (the orginal raiser + a calling station). I tell myself it's unlikely with the pre-flop action (a baby late position raise) that JJ-AA is out there, but a set is possible as is a flopped Str8. I'm ready to fold this one if played back at (Was betting at all OOP a mistake?).

Turn is a K, no flush yet. I tell myself that it's unlikely that the K helped either of them, unless it's a flush draw with KQs, KJs, KTs, etc. or they hold K8o (possible for the calling station, less likely for the tighter guy who raised pre-flop). I decide to come at it again for about half of the pot or so. Just the tighter guy calls. I'm a little worried now (should I have slowed down when the K hit or is my reasoning sound here?).

River is a blank. I could check here, but I'm worried that that might induce a missed draw to bluff and I can't call a big bet with this hand. I value bet something like $10 and get quickly called (should I have checked, since I was most likely against a busted draw or a better hand?)

Buddy has AA. I lose. WHY raise so small with AA from late position when the table calls $4 pre-flop for a joke? Bah!

Comments on this hand? Mistakes on the flop/turn/river (or all of the above)? Or just screwed by position once again?
